Q
  1. After glycolysis, if oxygen is present, what step(s) are next?
A

If there IS oxygen, then next it (what?) goes to the mitochondria (Krebs cycle) to which it then goes on the membrane (Electron Transport Chain) where 32 ATP is produced.

Q
  1. After glycolysis, if oxygen IS NOT present, what step(s) are next?
A

If there IS NO oxygen, then in animals glucose transforms into pyruvic acid through lactic acid fermentation (sore feeling, cheese, yogurt, sour cream). In yeast/bacteria, glucose transforms into pyruvic acid through alcoholic fermentation (alcohol, ethyl alcohol).

Q
  1. What occurs in prophase?
A

In prophase, the cell basically under goes preparation for duplication. To be more descriptive, chromatin coils up and forms chromosomes, the nucleolus and nucleus membrane (envelope) fade away which causes the nucleus to disappear, and then the spindle fibers for, between the centrioles.

Q

A

Incomplete dominance are cases in which one Allen is not completely dominant over another which an example being how a white flower and a red flower may produce a flower that is both red and white. Codominance is when an allele is neither dominant nor recessive with an example being the same two flowers except now they produce an offspring that is pink.

87
Q
  1. What did Lamark believe?
A

He believed that a) acquired traits choose what traits are passed on, b) here is a born desire to fit into an environment, and c) if you use a trait it will grow while if you don’t use it, it will shrink or disappear entirely

88
Q
  1. Give examples of adaption?
A

One example is how we adapted to standing upright and another is how, say, rabbits over time developed longer ears

89
Q
  1. What were the four lines of evidence Darwin said supported evolution?
A

Four lines of evidence Darwin used to support evolution were: 1) species change over time, 2) the goal of life was to survive and reproduce, 3) if you fit into the environment you will survive better, 4) changes changes happen over many generations, and 5) change mutations may increase fitness
