1. The ability to taste the chemical, phenylthiocarbamide (PTC), is determined by a gene on chromosome 7 that shows dominant inheritance. PTC-like chemicals are found in vegetables like broccoli and cabbage. Tasters don’t enjoy eating these types of vegetables while non-tasters don’t notice this bitter taste in these vegetables. (T= ability to taste PTC; t= non-taster) Determine the probability that the following couples (a, b, and c) will have a non-taster child. Support your answer with a Punnett square.
2. 1. Two tasters, who are both heterozygous:
3. 2. A non-taster marries a taster who is homozygous:
   3. Two non-tasters:
   4. Can a non-taster have 2 biological parents that are both tasters?

PARAGRAPH ANALOGY OF ACTION POTENTIAL

In a single paragraph discuss the process of an action potential. Explain it in a way that you would tell an eight year old - using an analogy. I would like to see you use an analogy and the more creative the better!

Note: You CANNOT use the domino effect or firing a gun as the analogy.

You must include four (4) of the following terms in your analogy: all-or-nothing response, axon, resting state, soma (cell body), threshold, positive or negative ions, depolarized, refractory period

In 2018, Isle Royale was home to only one or two highly inbred wolves. If humans had not intervened by introducing more wolves to the island, the wolves would have disappeared from the island. Tell what would have happened with the moose and plant populations in upcoming years if wolves disappeared from the island and explain why. Please outline a draft offline and then type your final answer in the box; the best answers will:

• be concise, without irrelevant or incorrect information
• include the relationships between wolves, moose, and island plants
• discuss carrying capacity and density dependent factors

what is the relationship between chlorophyll distribution and PSII activity for the chloroplast ?

In peas the flower color and pollen length genes are very close together on the same chromosome. Purple flowers (P are dominant to white (p), and long pollen (L) is dominant to short pollen (l). A true breeding variety of peas with purple flowers and short pollen is crossed to a true breeding variety with white flowers and long pollen. The F1 plants are then self-crossed to produce an F2 generation.

a. What is the genotype and phenotype of the F1 generation?

b. What proportion of the F2 will have purple flowers with long pollen?

c. What proportion will have white flowers and short pollen?

There are nine major phyla described - Mollusca, Porifera, Cnidaria, Platyhelminthes, Nematoda, Annelida, Arthropoda, Echinodermata, and Chordata,

1. which of these do you consider to be the most successful?

2.Explain your rationale for measuring success (e.g. total numbers, numbers of different species within the phylum, adaptability, specificity etc) and choose a representative animal within that phylum and discuss which aspects of its physiology and lifestyle have contributed to its success.
