Factors leading to degradation of DNA include all but:

How is evolution not just 'chance'?

Your answer

Are humans the only species that can learn 'language'? Consider the story of "Kanzi".

What segregates human communication from those of other apes?

1. name at least four mechanisms that may hold a hydrogel together without covalent bonds? In other words, physical crosslinking?

2. provide 2 examples on how pH sensitive polymers/hydrogels may be useful in biomedical field?

Please provide detain explanation how pH changed in human body and how the polymer in response to such change?

3. Why do think we need to incorporate cell instructive peptide (such as RGD) into PEG hydrogel

4. What are the two major degradable strategy in hydrogel?

What are the chemical components of normal enzymatic degradable crosslinker? Do you know why?

Explain the mechanism that electric fish use to produce electric organ discharges (EODs). Based on this explanation, why would a fish that uses EODs for hunting and defense be likely to be longer than one that uses electrical discharges solely for communication?

is it more energetically expensive to feed monosaccharides other than glucose into the glycolytic pathway? explain.

why is the cell's ability to regenerate NAD+ critical to glycolysis? which glycolytic enzyme requires NAD+?

List what transport protein you think is MOST important in the body. Defend your answer (provide your rationale). Obviously there are a LOT of choices.

why is antibody mediated immunity also referred to as hu moral immunity?

which cell type is most responsible for controlling a viral infection?

what are the defense mechanisms (cells) of specific immunity?

There are many different ways toxins are introduced into the environment. Using the textbook or another authoritative source chose a toxin that people can be exposed to and answer the following questions: What is the toxin and what is it primarily used for? How are people exposed and what are the potential problems? How can toxin exposure be prevented or what are known obstacles to prevention?

1. Describe conditions of early Earth that existed before the origin of life. Your description should include a brief explanation of the “massive bombardment” in addition to the other significant characteristics of early Earth.

2. Define evo-devo, heterochrony, and paedomorphosis. Describe an example to help explain the meaning of each of these terms.

3. Explain how the evolution of changes in temporal and spatial developmental dynamics can result in evolutionary novelties.(Suggested length of answer is a short paragraph, 2-5 sentences).

4. Explain why extracting a single (linear) evolutionary progression from a fossil record can be misleading. (Suggested length of answer is a short paragraph, 3-6 sentences).

5. Explain the statement: “Evolutionary change is not goal-directed”. (Suggested length of answer is 3-6 sentences.)

Fill in the chart to define negative control and positive control in terms of how the active forms of the gene regulatory proteins function. How does an inducer turn on a gene that is negatively controlled? How does an inducer turn on a gene that is positively controlled? Explain how a product turns off a negatively controlled gene, and how it turns off a positively controlled gene. Provide an example of each.

Discuss the potential uses of artificial cells and/or cell like materials and whether you consider them to be a good substitute for the natural versions.

Please cite credible resources.

how to answer these

1.     Discuss the effects of population size on both theeventual fate of an allele (fixation, loss) and time to fixation within a population. Describe the evidence from your simulations for these effects, citing specific examples.

2. What are the effects of genetic drift on genetic variation within and between populations? Describe the evidence from your simulations for these effects, citing specific examples.

Phylum Platyhelminthes.

whole mount of Planaria aka Dugesia

1. What are the two ways that the gut is similar to the gastrovascular cavities of cnidarian medusae?

2. Compare structures and anatomy of Bdelloura sp to Dugesia sp. How many differences/ similarities can you find?

Describe the history and the role of evolution and natural selection in ecology.
