Just answer the question in General. Don't need to use the graph

  1. Why can you kill the moths off in a few time steps? What does this indicate could happen in an environment to cause a species to go extinct?
  2. How could the model be modified so that the proportions of each moth color type would not change through time?

In the production of sperm, what happens to spermatocytes?

   a. They undergo mitosis to produce sperm cells.

   b. They undergo meiosis to produce sperm cells.

   c. They are sperm cells so they become part of semen and are ejaculated.

   d. They develop into self-renewing stem cells that maintain the testes.

Do women produce more eggs or do men produce more sperm? Why?  

a. Women produce more eggs because the odds of any one egg getting fertilized by a sperm are not good.

b. Women produce more eggs because they can’t move and so are stuck in one place. Because sperm can move, not as many are needed.

c. Men and women produce about equal amounts of sperm/eggs.

d. Men produce more sperm because they produce it all their lives, while women are born with all the eggs they’ll ever have.

Where do the hormones FSH and LH come from and what do they do in women?

a. The pituitary gland; FSH causes a follicle in the ovary to mature and release an egg, and with LH, stimulates estrogen secretion.

b. The hypothalamus; FSH causes a follicle in the ovary to mature and release an egg, and with LH, stimulates estrogen secretion.

c. The prostate gland; FSH causes a follicle in the ovary to mature and release an egg, and with LH, stimulates estrogen secretion.

d. The ovary; FSH causes a follicle in the ovary to mature and release an egg, and LH stimulates estrogen secretion.

What does your body need oxygen for?

Cells need it to produce the energy they need to function.

It is necessary to aerate the brain.

Air flow aids in blood flow within the blood vessels.

It produces hemoglobin, needed to carry carbon dioxide

Oxygen-poor blood

Blood toward the heart

Sperm cells are formed initially in the testes. What path do they follow to get to ejaculation?

   b. Prostate gland, epididymis, vas deferens, urethra

   c. Epididymis, vas deferens, vulva, urethra

   d. Vas deferens, prostate gland, urethra

A fetal ovary has all the mature eggs it will ever have. True or false?

   a. True. Women have all their mature eggs at birth.

b. False. The eggs in a fetal ovary pause after meiosis I and don’t mature until release from the ovary.

   c. False. Eggs don’t develop in the ovary until just before puberty.

   d. False. Eggs don’t mature until the moment of fertilization.

Where does the energy in an ecosystem come from initially?

   a. All the plants

   b. The sun

   c. The decomposers recycle it

   d. The lithosphere

How does energy from the sun become a type of energy an animal can use?

   a. Respiration

   b. Decomposition

   c. Photosynthesis

   d. Carbon cycle

Which of the following is the sequence of vessels the blood follows as it circulates?

a. Heart, veins, capillaries, arteries, heart

b. Heart, capillaries, arteries, veins, heart

c. Heart, veins, arteries, capillaries, heart

What challenges to solute concentration and/or water gains and losses does Loggerhead turtle experience? (I am looking for you describe why it might be difficult for an animal to live in this particular environment when considering its solute and water balance.)

How does the Loggerhead turtle deal with this challenge? (You should try to describe the general process as best you can in your own words. I am looking for our understanding of how this organism meets its environmental challenges with regards to solute and water balance.)

What anatomical structures are involved in meeting this challenge? (pictures are necessary)

What physiological processes are involved in meeting this challenge? (diagrams and illustrations will be very helpful. This is where you should be very specific about what happens in the body to balance solutes and/or water.)
