D huh I was stuck between both D and b
Explanation:
Answer:
My hypothesis is that the Hawaiian Island chain was formed by a hot spot in the middle of the Pacific Plate. While the hot spot itself is fixed, the plate is moving. My data supports my hypothesis because as the plate moved over the hot spot, the islands that make up the Hawaiian Island chain were formed.
I would give them water and when they start swimming it's a proof that they have been alive, after all, how would they start moving if they have been dead
Answer:
d. whether or not the traits were inherited from a common ancestor
Explanation:
Homology is a term used in the evolution biology to describe similar traits among two or more different species that came from a common ancestor species. On the other hand, homoplasy also refers to similar traits among different species but that evolved independently.
An example of homology are the forelimbs of frogs, birds, rabbits, and lizards.
An example of homoplasy is the eye.
<span>My pea plant has an unknown genotype for flowers, whether it has two dominant traits for white flowers (WW) or one dominant and one recessive (Ww) leading to white flowers; therefore I am doing a testcross in order to determine the genotype of my pea plant. The best plant to do this with is one that has a phenotype of purple flowers (ww) - that is, it is homozygous for the recessive trait.
If I use a homozygous recessive plant, I know exactly what its genotype is. I don't have to worry about whether it's got one or two dominant alleles; I know that at least half of my alleles are going to be the recessive w.
This makes identifying the offspring's genotype very simple. If I find that the offspring have at least some purple flowers among them, I know that my original plant had to be Ww; that is it had to have one dominant and one recessive allele for the flower color gene. If, however, all of the offspring are white flowers, I know that my original pea plant had both dominant alleles (WW).</span>
