The nose is ________________ to the mouth.

superior

How do you think the molecular weight of a substance will affect its rate of diffusion?

The greater the molecular weight, the slower the rate of diffusion; inversely proportional

Vertebral Cavity

Spinal Cord

Endoplasmic reticulum

Site of protein and lipid synthesis depending on whether is is "rough" or "smooth"

List 4 organs that are found in the Abdominal Cavity: Use the following terms to fill in the blanks. Heart Pancreas Lungs Liver Stomach Kidney Brain Urinary Bladder Small Intestine Adrenal Gland LargeIntestine Uterus Spleen Larynx

- small intestine -large intestine -liver -spleen

Which of the following are true of diffusion? (Select multiple)

-Diffusion is a passive process -Substances move from areas of low concentration to areas of high concentration -Substances move from areas of higher concentration to areas of lower concentration

Select the transport mechanisms that do not require energy. (Select multiple)

-Osmosis -Facilitated Diffusion -Simple diffusion

Which of the following factors can effect the rate of diffusion (as determined in lab today)? (Select multiple)

-Temperature -Viscosity -Size of the particles -Molecular Weight

Which of the following events occur during Interphase?

-The chromosomes line up in the center of the cell -DNA is replicated -Enzymes and proteins are synthesized -The organelles are replicated

In lab today, what happened to the red blood cell when it was placed into a hypotonic solution? (Select multiple)

-Water moved into the red blood cell -It swelled/burst

Which of the following statements are true regarding Diffusion? (Select Multiple)

-a substance moves down its concentration gradient -the temperature of the solution will effect diffusion rate -it is a passive process

What would happen if a cell is placed into a hypertonic solution? (Select Multiple)

-water would move out of the cell -the cell would shrink/crenate

List the 4 phases of Mitosis in order

1. Prophase 2. Metaphase 3. Anaphase 4. Telophase

The cell must produce energy in the form of ATP to allow which transport process to occur?

Active Transport

Cranial Cavity

Brain

Nucleus

Contains genetic information. Instructions for protein synthesis and cell reproduction

As the viscosity of a substance increases, will this increase or decrease the rate of diffusion?

Decrease

In a negative feedback system, if blood pressure is increasing, will it continue to increase or will it decrease?

Decrease

Upper Middle Region (abdominal cavity)

Epigastric

At what point is there no more net movement of water in osmosis?

Equilibrium

Diffusion involves the movement of a solute from an area of low solute concentration to an area of higher solute concentration.

False

The cell membrane is a semipermeable membrane. This means that the membrane allows for all substances to pass between the intracellular and the extracellular space.

False

During the process of ___________, a solvent will move from a region of high pressure to a region of lower pressure.

Flitration

Lower Center Region (abdominal cavity)

Hypogastric Region

In lab today, we placed potassium permanganate crystals in varying temperatures of water. In which temperature did the crystals diffuse the most rapidly?

In the hot/boiling water

Lower Left Region (abdominal cavity)

Left Iliac Region

Middle Left Region (abdominal cavity)

Left Lumbar Region

Upper Left Region (abdominal cavity)

Left hypocondriac region

When considering water concentration, a low concentration of water has ____________ dissolved particles than a high water concentration

More

In lab today, we put glucose and starch into dialysis tubing which was then placed in water to determine what would diffuse or pass through the semipermeable membrane. Did starch pass through the membrane? Why or why not?

No, it did not pass through because starch is a large polysaccharide

Net movement of water from one side of a selectively permeable membrane to the other

Osmosis

Mitochondria

Powerhouse of the cell

Lower Right Region (abdominal cavity)

Right Iliac Region

Upper Right Region (abdominal cavity)

Right hypocondriac region

Middle Right Region (abdominal cavity)

Right lumbar region

In lab today, did the potassium permanganate or the methyl blue diffuse more rapidly in the agar and why?

The potassium permanganate diffused more rapidly because its molecular weight is less

If temperature increases, how do you think this would affect the rate of diffusion?

The rate of diffusion will increase

Golgi apparatus

This organelle packages proteins for export from cell and forms secretory vesicles. The postal system of the cell

In lab this week, you will be conducting experiments to test the effects of viscosity, temperature, molecular weight and particle size on diffusion rate and observing the instructor demonstrate osmosis, cell tonicity, and filtration.

True

The new nuclear envelopes form around each set of chromosomes to form two separate nuclei in telophase

True

The plasma membrane is composed of lipids and proteins.

True

Center Region (abdominal cavity)

Umbilical Region

Movement of water in osmosis is from high to low _____________ concentration.
