Biology questionss!! (these r different)?

Question

Explain if you can please!

All of the following are evidence for evolution EXCEPT
A. the presence of anatomical homologies
B. vestigial organs
C. the existence of molecular homologies
D. the fossil record
E. the existence of homologies in diet among species

in a certain group of iguanas, the presence of brown skin is the result of a homozygous recessive condition in the biochemical pathway producing pigment. if the frequency of the allele for this condition is .35, which of the following is closest to the frequency of the dominant allele in this population (assume the population is in hardy-weinberg equilibrium)
a. 0.15
b. 0.45
c. 0.55
d. 0.65
e. 0.85

In which of the following pairs are the organisms most closly related taxonomically?
a. mushroom;tulip
b. e.coli;euglenid
c. lobster;spider
d. shark;crayfish
e. dolphin;sea star

Answer 1

#2 is d. If the recessive allele has a frequency of 0.35, then the dominant allele must have a frequency of 0.65. From the Hardy-Weinberg equations, p + q = 1, and q is the frequency of the recessive allele.

For #1, similarities in diet is not necessarily evidence for evolutionary relatedness.

For #3, I think both lobsters and spiders are arthropods.

Answer 2

1 E
2 ?
3 C

Answer 3

For the first question I'm pretty sure its E, just because I've learned all the others ones, but never heard anything about the diet stuff.
Question two is D b/c the total for alleles must equal 1
Question three is C b/c bother are in the pylum arthropoda. All others are in different phylums

Answer 4

1-E (diet is the only irrelevant)
2-D (total must equal 1)
3-C (both in "arthropoda")

Answer 5

nothing evidences evolution. just theory. a pretty crappy one.
