The genotypes that indicates a homozygous dominant trait is : B. TT
Homozygous : both alleles must be the same, so it eliminate option A.
Dominant trait : One of the allele must be written in Capital letter, so it eliminate option C.
this leaves option B, as the answer
hope this helps
<span>The organism will produce 12 chromosomes (A).
Sex cells are the products of meiosis. Daughter cells of meiosis contain half the number of chromosomes of the parent cell. So if the parent cell has 24 chromosomes, then the sex cell would have <em>12 chromosomes</em>.</span>
Answer:True
Explanation:Basically thymine diamers are mismatched pairs (thymine binds with another thymine instead of binding with adenine) and may lead to unwanted results so the mismatching can be repaired by using two methods which are as follows :
1-the PRE enzyme activated by blue light breaks the thymine diamer and some of the surrounding bonds the strand is cut and DNA polymerase then restores the normal base pairing
2-UVR system breaks dimer creating a gap when a gap is created and the molecules appear unpaired it is filled by proof readers hence restoring normal base pairing.
Answer:
They are adapted for photosynthesis by having a large surface area, and contain openings, called stomata to allow carbon dioxide into the leaf and oxygen out. Although these design features are good for photosynthesis, they can result in the leaf losing a lot of water. The cells inside the leaf have water on their surface. Some of this water evaporates, and the water vapour can then escape from inside the leaf.
