If you add 100 ml of 50X TAE to 900 ml of water

a. What dilution did you perform?

b. Did you dilute the concentrated TAE to 1X?

c. What dilution is required to get to 1X?

d. To make 500 ml of 1X TAE Buffer, add _____ml of 50X TAE to _____ml of water

Describe transition state theory and how it applies to enzyme catalysis. Why is a transition-state analog not necessarily the same as a competitive inhibitor?

In elephants, the allele for the prehensile trunk, T is dominant over the allele for a non-grasping trunk, t; the allele for floppy ears, E is dominant over the allele for pointy ears, e; and the allele for pointy tusks, P is dominant over the allele for blunt tusks.

If you were to cross a trihybrid elephant with a pure-breeding elephant with a prehensile trunk, pointy ears, and blunt tusks, what proportion of the offspring would have a genotype of TtEepp?

Please show your work

a) 0 (that genotype cannot be formed by this cross)

b) 1/8

c) 1/4

d) 1/2

e) 9/16

Please provide a presentation, in table form, of the primary tissue types found in plants.

Make sure to include: dermal, ground and vascular, epidermal, parenchyma, collenchyma, sclerenchyma, xylem, phloem, vessels, tracheids, sieve tube elements, companion cells, fibers, sclereids.

Why do we call water the universal solvent? All life, as we know it, needs water. What is the importance, relative to water being a universal solvent, to living systems?

How do molecules like pyruvate, phosphate, ADP, and ATP get into the mitochondria matrix?

In only 3 sentences, compare and contrast the following:

a) CAM and C4 plants

b) Micronutrients and macronutrients (with examples)

c) Apical meristems and lateral meristems

In what experiment situation would the techniques of confocal microscopy, transmission

electron microscopy, and scanning electron microscopy be best used? What types of

information could you receive from each?

Ketone bodies are synthesized from acety-CoA only when carbohydrates are not available. Why is this the case? Consider how gluconeogenesis, TCA, ACC, and circulating hormones play a role in directing carbon toward these molecules.

Provide an example of a simple/basal nervous system and a complex/derived nervous system. Explain how their functions differ.

30 ) Which of the following statements about the Lac operon is false?

40 Which of the following statements about the cytoskeleton is false?

Help please both of them thanks

You cross true breeding blue and red morning glories and get all blue offspring.

a) Based on this information alone:

i) How many loci are involved in the expression of this trait? How many alleles? What are the dominant and recessive interactions between the alleles at the locus/loci?

ii)what are the possible genotypes of the parents and F1s?

iii) Based on your hypothesized genotypes from ii, what do you expect the outcome of a cross between the F1's to be? (i.e. what phenotypes in what ratios?)

b) You then cross the F1 individuals and you obtain the following results

Blue - 200

purple - 126

red - 24

i) Are these results statistically consistent with your hypothesis above?           (prove it!)

ii) If not, what is an alternative hypothesis that might explain these results? Are these results the result of one locus or 2? Test your new hypothesis using chi-squared test. Discuss the meaning of your results. (Note: If your hypothesis proves wrong, that is OK!!! But you have to be able to discuss why you think it's wrong.)

Explain the process of fermentation that takes place in eukaryotic cells, such as muscle cells.

Why are the products of fermentation necessary for anaerobic respiration to continue?
