1) For each observation below, state a question (of your choosing based on the observation), hypothesis, prediction, and describe what you would do to test your prediction (based on the question you propose, this would be the experiment). For your description of how you will test the prediction, you do not need to protocol, simply state in a few sentences how you would go about testing it to determine if your prediction was supported or not.
a. You are walking to your car and notice that the trees are beginning to flower and that there is a yellow 'dust' all over the cars in the parking lot.
b. While in the supermarket you notice that there are many different colors of apples for sale.
2) Compare and contrast DNA and RNA (remember there are 3 types of RNA) in terms of the following:
a. Their function (what they are used for)
b. Their location (where they are found in a prokaryotic and eukaryotic cell)
c. Their composition (chemically what they are composed of)
3) Describe what the following cellular components are and their function
a. Mitochondria
b. Chloroplast
c. Plasma Membrane
d. Endoplasmic Reticulum (both types)
e. Ribosome
f. Golgi Apparatus
4) Explain how the carbon cycle works in terms of photosynthesis and respiration. To answer this you will need to discuss how carbon moves through these two processes including any instances of carbon 'outside' of these systems.
5) Calculate the following genetic problem and answer the questions.
a. Assume that in seals, whisker length is controlled by a gene with 2 alleles. The dominant allele (W) produces long whiskers and the recessive allele (w) produces short whiskers. What is the possibility of producing a short whiskered offspring from the mating of a homozygous dominant and heterozygous parent?
Fill in the Punnett square (by clicking in the areas you wish to input text, the boundaries of the box are removed where you input the alleles from each parent to make it look like a Punnett square you would draw on paper) and give the % prediction for the possibility of producing a short whiskered offspring from this mating. It doesn't matter which side you put male or female gametes, as long as you remember which is which (you can assign either to the genotypes above.
What is the % chance of having a short whiskered offspring?
b. If one parent seal is heterozygous long-whiskered and the other is short-whiskered, what is the probability of producing a short-whiskered offspring? Show your Punnett square and give the % chance for a short whiskered offspring. Fill this out the same way you did above by clicking on the boxes and indicating the % chance of that genotype in the offspring.
What is the % chance of having a short whiskered offspring?
6) Explain the 4 levels of protein structure, giving details for each.
7) Explain your favorite and least favorite topic this semester. Here you should indicate which each is and tell me some things (give 3 facts or details about each) about that topic and why you either like or did not like the topic. This question is mostly opinion, but make sure you get the facts correct that you are stating about each you choose.
