The
correct answer is no.
<span>The
development of retinoblastoma occurs as a consequence of mutation of genes RB1
or MYCN. Those mutations occur in the early stages of fetal development and affect
the way in which cells grow and develop within the body. The more common is the
defective RB1 gene that can be inherited from either parent. The expression of
the RB1 allele is autosomal dominant.</span>
Answer:
The correct answer would be C. The tortoises provided evidence that different species have adaptations suited to their particular environments.
Darwin observed that how different environment on different island lead to the development of different species as a result of adaptations and natural selection.
For example, tortoise inhabiting well-watered islands which used to have short and cropped vegetation had developed a dome-shaped shell.
In contrast, the tortoise inhabiting the arid islands had developed saddle-shaped shells. It is because they needed to stretch their necks in order to reach branches of cactus and other vegetation available in the area.
Consequently, they developed long necks and high peak to the front edges of their shells. It made it possible for them to stretch their heads vertically.
I am not entirely sure about this. So maybe my response can help you find the answer a little better if my answer is not entirely right?
These last three questions are referring to everything you just worked on. So all you would have to do is refer back to your previous answers. Recall that the titles of the "part 1, 2, and 3" are titled "crossing beak color and tail-feather length", "crossing beak color and feather color", and "mapping tail-feather length and feather color".
1.List the distances between each pair of genes:
beak color and tail-feather length: 20 MU
beak color and feather color: 16 MU
tail-feather length and feather color: 4 MU
2.Which two alleles are the farthest apart?
(the one that is 20 MU apart) Y and L
3.Which two alleles are the closest together?
(the ones that are 4 MU apart) L and B

Answer:
Both are considered macromolecules. I'll explain below
Explanation:
Proteins are like a huge Lego construction. Each individual piece gets pieced together to make a larger "thing" - Death Star, House, etc. Each individual piece is a monomer, and the larger construction is the polymer. The monomers are Amino Acids and they get pieced together to form the polymer that is called a protein. The linkage that they use is an amide bond, and in biology it is usually called a peptide bond.
Carbohydrates can be singular monomers or polymer units. They are made of completely different compounds - usually aldehydes or ketones. And they link together through different chemical linkages (acetal or ketal linkages for polymers,hemiacetal or hemiketal linkages for monomers).
Both can be large, 3D strucutres - proteins are only functional as a large, 3D structure, while carbohydrates can be singular.
