TEAS Missed Questions

An anabolic reaction is a reaction that uses energy to build molecules the organism needs.

A catabolic reaction breaks down complex molecules into smaller molecules to create energy for the organism to use.

Which of the following cause lactic acid to build up in muscle cells?

The lack of oxygen leading to increase fermentation.

Which of the following digestive organs contains vitamin-producing bacteria? Stomach Liver Large intestine Small intestine

The large intestine contains healthy gut bacteria that are responsible for producing Vitamin K, a fat-soluble vitamin that plays a role in blood clotting. Often-times newborns are given a Vitamin K shot to aid in blood clotting due to any trauma during the birthing process. This is done because the gut bacteria has not yet populated and synthesized Vitamin K.

Which of the following describes the action of HISTAMINE as a response to a bee sting?

Histamine is a vasodilator and males blood vessels more permeable. This brings cells that fight infection to the site of injury quickly.

What are 3 hormones that the kidney produces?

1. Renin ( angiotensin system (RAS) 2. Erythropoietin (EPO) 3. Vitamin D3

Vitamin D is required for the intestinal absorption of which of the following substances? A - Calcium B - Potassium C - Iron D - Sodium

A - Calcium (correct) The synthesis of the carrier protein that is involved in the active transport of calcium in the small intestine is dependent on vitamin D. Calcium can also be absorbed through a passive process that does not involve or require vitamin D when a person's diet is high in calcium. B - Potassium Potassium diffuses through the small intestine, in the ileum and jejunum sections, on its own. This is a passive process that does not require the help of vitamin D. C - Iron Iron is absorbed directly by mucosal cells in the duodenum section of the small intestine without the help of vitamin D. D - Sodium Sodium is absorbed in the small intestine through active transport. It is often co-transported with glucose and amino acids, but vitamin D does not play a role in the active transport of sodium in the small intestine.

Which of the following hormones increases the most after ovulation occurs? A - Progesterone B - Estradiol C - Follicle stimulation hormone D - Luteinizing hormone

A - Progesterone (correct) Progesterone is secreted by the corpus luteum that forms after ovulation. It promotes the thickening of the endometrium. B - Estradiol Estradiol, which is a form of estrogen, is also secreted by the corpus luteum that forms after ovulation. It promotes the thickening of the endometrium, but more progesterone is released than estradiol. C - Follicle stimulation hormone Follicle-stimulating hormone (FSH) decreases after ovulation. It stimulates the growth of the follicle and increases prior to the follicle rupturing, which then releases the secondary oocyte through ovulation. D - Luteinizing hormone Luteinizing hormone (LH) decreases after ovulation. It stimulates the growth of the follicle and increases prior to the follicle rupturing, which then releases the secondary oocyte through ovulation.

Which of the following are produced from the reaction between a Brønsted-Lowry acid-base pair? Water and a strong base A salt and water A weak acid and base A strong acid and weak base

A Brønsted-Lowry acid donates a proton (H+) during a reaction. When the protonated species is a base, the hydroxyl (-OH) from the base combines with the H+ of the acid to form water. The counterions of the acid and base combine to form a salt.

Which of the following cells rid the body of dust and other particles that enter the lungs? Alveoli Macrophages Sertoli cells erythrocyte

Alveolar macrophages are abundant in the ling and remove particle that escape entrapment by mucus.

Identify the acid in the following reaction: CH3COOH + NaOH → NaOOCCH3 + H2O NaOOCCH3 CH3COOH H2O NaOH

Answer: CH3COOH The acid in a reaction is the species that donates a hydrogen (H) to the base (NaOH in this reaction). In the reaction above, CH3COOH donates a H to NaOH to form NaOOCCH3 and H2O. The name of this acid is acetic acid, which is also called vinegar.

Which of the following is an example of a redox reaction? Single replacement reaction Synthesis Acid-base neutralization Combustion

Answer: Combustion A redox reaction is one that involves the transfer of electrons between two species. The substance that gives away electrons is said to be oxidized. The substance that receives the electrons is said to be reduced. During combustion, elemental oxygen (O2) reacts with a compound to form products that contain oxygen. This requires oxygen to transition from a neutral oxidation state (0) to an oxidation state of -2. (The oxygen has been reduced.) In the other reaction choices, the oxidation states of atoms do not necessarily change.

From the collecting ducts, urine is transported to the minor calyces, which converge to form major calyces. The major calyces converge to the renal pelvis, then the urine is transported to the ureter, followed by the urinary bladder and is finally excreted via the urethra. Please see the diagram below as a visual reference for the anatomy and processes of the kidney referenced in the question above.

Answer: Creatinine Amino acids, sodium and glucose are normally reabsorbed in the proximal portion of the renal tubules. Creatinine, which is used to assess glomerular filtration, is filtered in the glomerulus and also secreted by the tubules.

The nurse inferred the patient hadn't been taking his treatment because his hands were shaking again. Which of the following is the meaning of the word "inferred" as used in the sentence above? Deduced Exclaimed Mumbled Objected

Answer: Deduced The correct meaning of the word is "deduced", as it portrays the idea that the nurse was attentive to detail and concluded the patient was not taking his medicine. "Exclaimed" is not the correct meaning, as it would suggest that the nurse said out loud that the patient hadn't been taking his treatment. "Mumbled" is not the correct meaning, as it would suggest that the nurse whispered that the patient hadn't been taking his treatment. "Objected" is not the correct meaning, as it would suggest that the nurse said the patient had been taking his medicine and thus his hands where shaking.

Which will occur if a person who has blood type A receives type B blood?

Antibodies against blood type B will be produced in the recipient's blood plasma. Exposure to blood type B will cause antibodies against antigen B to be produced.

A student needs to accurately measure 17 mL of a solution to use in an experiment. Which of the following pieces of equipment should the student use? A - Beaker B - Graduated cylinder C - Dropper pipette D - Electronic balance

B - Graduated cylinder (correct) The main function of a graduated cylinder is to measure the volume of a liquid. A - Beaker Beakers are generally used for stirring, mixing, and heating liquids, not for measuring the volume of a liquid. Although there are graduated beakers, the markings are only approximate, and, thus, they are not as precise as graduated cylinders, especially for smaller volumes such as 17 mL. C - Dropper pipette The main function of a dropper pipette is to transfer liquid from one container to another. D - Electronic balance The main function of an electronic balance is to measure the mass of an object.

In which of the following locations do most WBCs originate? Bone marrow pancreas Spleen large intestine.

Bone marrow

Which of the following steps of protein synthesis occurs in the nucleus? A. Replication B. Elongation C. Transcription to mRNA D. Translation to amino acid

C. Transcription to mRNA Protein synthesis is comprised of two main steps, transcription of DNA to mRNA and translation of mRNA codons to amino acids. In the nucleus, the mRNA transcribes the genetic instruction from the DNA. mRNA then diffuses to the cytoplasm through the nuclear pores. Translation to amino acid and elongation to a particular protein molecule occur in the cytoplasm, particularly in the ribosomes.

Chemical mineral found in bones that provides mechanical strength and is found in teeth and bones?

Calcium hydroxyapatite.

Line Chart

Can be used to show changes in amounts over time. It is appropriate for displaying one or more sets of continuous date.

Which of the following explains what happens in the circulatory system during hyperventilation?

Carbon dioxide levels decrease, causing an increase in blood pH. As carbon dioxide levels decrease, the blood becomes more basic, increasing blood pH.

Which of following glands in the skin is not correctly paired with its secretion? Apocrine sweat glands/ odoriferous perspiration Ceruminous glands/ sebum Eccrine glands / perspiration necessary for evaporative cooling Sebaceous glands / oil

Ceruminous glands/ sebum

Which of the following is the correct order of structures that transport urine from the collecting ducts to the urethra?

Collecting ducts, Minor calyces, Major calyces, Renal pelvis, Ureter, Urinary bladder, Urethra From the collecting ducts, urine is transported to the minor calyces, which converge to form major calyces. The major calyces converge to the renal pelvis, then the urine is transported to the ureter, followed by the urinary bladder and is finally excreted via the urethra. Please see the diagram below as a visual reference for the anatomy and processes of the kidney referenced in the question above.

In order to break apart a polysaccharide into disaccharides, what type of reaction needs to occur? A. Glycosidic B. Condensation C. Oxidation-reduction D. Hydrolysis

Although my son doesn't like playing sports, he makes beautiful drawings when he stays at home. B. Since my son prefers to stay at home and make beautiful drawings, he doesn't like playing sports. C. Not liking playing sports, my son makes beautiful drawings to stay at home. D. My son doesn't like playing sports; instead, he prefers to stay at home and make beautiful drawings.

D. My son doesn't like playing sports; instead, he prefers to stay at home and make beautiful drawings. When combining sentences on the TEAS, your answer needs to follow two rules: The meaning of the original sentences must be the same. The combined sentence must be clear and grammatically correct. When doing these problems, the simplest, clearest sentence that does not change the meaning of the original statement will be the best answer choice.

Which of the following describes cellular respiration? A. It is a reductive catabolic activity B. It is a reductive anabolic activity C. It is an oxidative anabolic activity D. It is an oxidative catabolic activity

D. Oxidative Catabolic activity Cellular respiration is the process in which a cell takes in oxygen and uses it to break down glucose to create energy in the form of ATP. In the final stage of cellular respiration (called the electron transport chain), oxygen accepts electrons and picks up protons to form water. So, because elements lose electrons to oxygen and it is a reaction in which energy is created, cellular respiration is both an oxidative and catabolic activity.

Which of the following is a type of specialized antigen-processing cell that activates T-cells of the immune system? Plasma cells thrombocytes dendritic cells eosinophils

Dendritic cells process antigens and display then on surfaces receptors to helper T cells of the immune system. Helper T-cells then active cytotoxic T-cells and B-Cells. Therefore, dendritic cells link the passive and active immune system. Plasma cells produce antibodies and are NOT involved in T-cell activation!

Bar Graph

Which of the following fetal tissues contributes to the formation of the placenta? Henatioiuetuc cells embryonic yolk sac fatal chorionic tissue fetal muscle tissue

Fetal chorionic tissue

I vs me

For this example, we use the pronoun "I" because it is the subject of the sentence. The pronoun "I" is used to refer to the speaker when he/she is the subject of a sentence. You can ask yourself, is the speaker the one doing the action in the sentence? The pronoun "me" is used to refer to the speaker when he/she is the object of an action of a verb in some way, either directly or indirectly. You can ask yourself, is the speaker experiencing the action of the verb in some way? This also means that "me" will be used when the speaker is referring to themselves in the predicate of the sentence.

Scatterplot

Is used to display discrete data.

Which of the following pairs of endocrine glands are linked by a venous blood portal system?

Hypothalamus and anterior pituitary They are linked by the hypophyseal portal system.

Flow Chart

Keratin

Which of these statements is true about pH? A.. A pH of 6 is more acidic than a pH of 8 B. Blood has an acidic pH C. Higher pH values indicate a higher [H+] D. Adding an acid to a solution will increase the pH

Lower pH values indicate a more acidic solution, thus 6 is more acidic than 8. This occurs because acids increase [H+] of a solution, which lowers the pH of a solution. Thus, higher pH values would have a lower [H+]. Blood has a pH between 7.35 and 7.45, so it is slightly basic. You may use the diagram below as a visual reference for the pH scale.

Which of the following organelles plays a vital role in the breaking down of macromolecules? Rough Endoplasmic Reticulum Golgi Apparatus Lysosomes Ribosomes

Lysosomes are responsible for digesting molecules/ substances being transported inside the cell from the outside, such as during phagocytosis by macrophages.

______ is an inflammatory conditions of the joints brought on by the gradual wear-and-tear of cartilage that lines the articular ends of bones.

Osteoarthritis

Oxidation is when an element loses one or more electrons to oxygen.

Reduction is when an element gains one or more electrons.

Pancreatic secretions that aid in digestion of food are produces by which of the following types of cells? Islet alpha cells Islet beta cells Acinar cells Sphincter cells

The acinar cells are the site of production of exocrine secretions of the pancreas such as amylases, lipases, and nucleases. Acinar cells are cells at the secretory cells found in a gland duct. Alpha cells- produce the hormone glucagon. Bata cells- produce the hormone insulin.

Valance Electrons

The outermost occupied electron shell of an atomic is called the valence shell. The electrons in the valence shell determine the chemical properties of that atom (and element). Electrons in the valence shell are known as valence electrons.

Predicate

The predicate is the part of a sentence or clause containing a verb and stating something about the subject.

Which of the following scenarios will increase the likelihood of reactant molecules colliding with one another during a liquid chemical reaction? Decreasing the pressure of the reaction Reducing the concentration of the reaction Increasing the reaction concentration Increasing the pressure of the reaction

The rate of a reaction depends on the frequency at which reactant molecules collide with one another. By increasing the concentration of reactants, there are more molecules of reactants in a given space, which increases the likelihood that these molecules will collide with one another. The question specifies that the reaction is liquid, which means that increasing the pressure will have no effect on the reaction rate, since this only affects gaseous reactions.

The spectacle, _____ John found extremely boring, reminded me of my childhood in the countryside. Which of the following pronouns correctly completes the sentence above? whom that who which

The words "which" and "that" can be used as relative pronouns, and follow these rules: Which is used with a clause that does not provide essential meaning. This means that if it were to be removed, it would not change the essential meaning of the sentence. In this example, the fact that John found the spectacle boring could be removed without changing the essential meaning of the sentence, which is that the spectacle reminded the speaker of his childhood. That is used in a clause that is essential to the meaning of a sentence. This means that if the clause were removed, it would change the essential meaning of the sentence. For example, "The cat that scratched my mother is no longer allowed outside." Removing "that scratched my mother" is necessary to understand the full situation and could not be removed without changing the meaning of the sentence. Hint: "which" is used in clauses that are typically offset by commas, whereas clauses that use "that" do not use commas.

Which of the following hormones requires iodine for its production? Thyroid hormones melatonin PTH calcitonin

Thyroid Hormones The human body cannot produce it own iodine, which is necessary to produce the two thyroid hormones: Thyroxine and triiodothyronine.
