Answer:
A. 100%.
Explanation:
Since both spiders have either AA or aa, every possible combination would result in an Aa genotype. And, because A is dominant to a, they will all display the A trait—be patterned instead of plain.
So it is 100%.
Mucilaginous sheath. Cyanobacteria are microorganisms that have survived for a thousand years now. They process and create their food through the photosynthetic mechanisms they possess and this process also includes nitrogen fixation and other biogeochemical process that contributes to most cycles.
Answer:
The macromolecule that is a nucleic acid is D, an RNA molecule.
Explanation:
Being as both DNA and RNA are nucleic acids, here is an explanation. DNA's structure is in the shape of a double-stranded helix while RNA's is structured as a single-stranded helix. DNA's backbone is made of the sugars deoxyribose and phosphate while RNA's backbone is made of the sugars ribose and phosphate. DNA also contains the bases adenine, thymine, cytosine, and guanine (adenine bonds with thymine and cytosine bonds with guanine) while RNA contains all said bases, except thymine is replaced with uracil (because of this change, the new bases pairings are adenine and uracil and still cytosine and guanine).
