Divide your current points earned by the total number of points that have been assigned and graded.
How can you calculate your grade at any point in the semester?
Log into the TAMU Google Drive with your TAMU credentials.
How should you access the Google Drive to review* lectures that have been recorded?*Remember, these lectures are recorded for any technical issues we may have. They are NOT recorded for students to use to "take" the course. This means that you will not be able to binge-watch these lectures and succeed in the course. -Log into Google Drive with your Google credentials. -Log into the TAMU Google Drive with your TAMU credentials. -Log into the TAMU Google Drive with any Google credentials. -Log into Google Drive with your TAMU Google credentials.
control groups
Hypothesis based science requires: -ignoring experimental evidence that does not fit with the original hypothesis -that the hypothesis be correct -control groups -being able to test and prove your hypothesis
Either the tattoo or the missing toe.
If LaMarck was correct in his idea about the inheritance of acquired traits, which of the following would you be able to pass along to your offspring? -A tattoo you got on your 30th birthday. -Your natural blue eye color. -Your missing big toe after you lost it in an unfortunate corn hole accident. -Either the tattoo or the missing toe.
No. No you cannot do this. Please do not do this. This is considered academic dishonesty and we have no choice but to report you to the honor's council.This is the answer. This is the only answer, because we ALL need to understand this. This literally happens every semester and it's not fun for anyone. Please do not do this.
If you are retaking this course, you can resubmit your lab assignments for credit with no penalty.
Your actual TA
If you have questions regarding a lab assignment or experiment, who should you contact first? -Your lab partner. -Your lecturer. -Your friends/roommate's TA. -Your actual TA.
Two species in the same family must be in the same taxonomic "Order".
In taxonomy, what is true about the hierarchal rank of "family"? -Two species in the same family must be in the same taxonomic "Order". -One species can belong to more than one family (but no more than 3 families). -Members of the same taxonomic family can have some species with a nucleus and some without. -Two species in the same family must be in the same taxonomic "Genus". -A family will usually include far fewer taxa (plural of taxon) than a genus.
Yes, you can participate in in-class Learning Catalytics (LC) sessions.
Is there any opportunities to "bump" up your overall course grade?
differential reproductive success of different phenotypes
Natural selection is: -a product of the genotype and environmental factors -differential reproductive success of different phenotypes -the natural "force" causing random changes in the gene pool -change over time -the ability to survive and leave offspring

(P1/12) Refer to the phylogenetic tree above to answer this question. The most recent common ancestor of the minke whale and the sheep is at branchpoint 4 3 5 1 2
the growth or height of the plants
Suppose you wanted to test the effect of fertilizer on the growth of tomato plants. What is the dependent variable? -The growth, or height, of the plants. -The amount of time that the plant was allowed to grow. -The type of fertilizer used. -The presence or absence of fertilizer. -The amount of water applied to each plant.
proving the hypothesis
The scientific method has great flexibility in the order of operations. Which of these is NOT a step in the process? -proper experimental design -making an observation -proving the hypothesis -communicating the results -repeating the experiment
The class will be held on the days and times as denoted on Howdy. Meaning, attendance is required.
What does it mean to be in an online course that is taught synchronously? -The class will be held on the days and times as denoted on Howdy. But, attendance is not required. -The class can be taken at your pace, no days/times are mandatory you just need to get the work done. -The class will be held on the days and times as denoted on Howdy. Meaning, attendance is required. -Only lectures are online.
They are due each Monday by 7:59AM (CST) no matter what day or time your lab session is.
When are your weekly PRE lab quizzes due?
Friday, Dec 4th from 11:00am - 1:30pm CST.
When is your BIOL 111 Fall 2020 Final Exam? -We don't have a final exam for this course. -Friday, Dec 4th from 11:00am - 1:30pm CST. -Whenever you complete the material for the course and feel ready. -Friday, Dec 4th from 2:55pm - 3:45pm CST.
All cells have a nucleus
Which of following is not a tenet of the cell theory? -Cells can only arise by division from a preexisting cell -All organisms are composed of one or more cells -All cells have a nucleus -The cell is the structural unit of life
Developing and implementing a successful vaccine against Covid-19.
Which of the following is an example of applied science? -Exploring and mapping out the phylogenetic history of Covid-19 (especially in relation to other corona viruses). -Determining which groups of people are more susceptible to severe complications due to Covid-19. -Tracking down "patient zero" for Covid-19. -Developing and implementing a successful vaccine against Covid-19.
A functional camera and access to Zoom
Which of the following is required for use in all of your exams?
Your correct UIN.
Which of the following pieces of information is absolutely required to be input in your Learning Catalytics account for you to received credit for participating in sessions? -Your correct UIN. -Your social security #. -Your bank account #. -Your TAMU email.
responding to the environment.
Which of the following properties or processes do we associate with living things? -sexual reproduction. -natural selection. -nucleated cells. -responding to the environment. -creating energy.
heritable variation in the population
Which of these factors are required for biological evolution to occur? -variation in acquired traits among individuals in the population -natural selection -heritable variation in the population -many generations -a large population
the independent variable has no effect on the dependent variable
A null hypothesis states that: -the independent variable has no effect on the dependent variable -there is no hypothesis that can be made -there is no control group in this type of experiment -the dependent variable has no effect on the independent variable
Both mutations or gene flow could allow this to happen.
A population of plants is growing in a nice, moist rain forest. All of the plants have equally thin, broad leaves that lose water quickly (which is ideal in this environment). Which of the following could add a new heritable variation providing thicker, tougher leaves that would make the plants more drought-resistant? Environmental change: a drought could stress the plants, making them grow thicker leaves that they would pass to their offspring in order to survive. -Mutation: a change to DNA in a sperm or egg could produce a new gene that controls leaf thickness. -Gene flow: pollen from a nearby population of plants with thicker leaves could fertilize a flower and bring a new allele into the gene pool. -Natural selection: survival of the fittest could create a new genetic adaptation like thicker leaves if it was needed. -Both mutations or gene flow could allow this to happen.
is carefully-formulated proposition, based on observation, and supported by an accumulation of experimental data
A scientific "theory": Answers: -is a hypothesis that has yet to be subjected to experimentation. -may have been found to be false under some particular set of circumstances. -is a well-thought-out potential explanation for a phenomenon. -is a carefully-formulated proposition, based on observations, and supported by an accumulation of experimental data. -may incorporate explanations involving processes other than physical phenomena.
