Biology
1 answer:
Rainbow [258]2 years ago
7 0

Answer:

Base

Explanation:

Deoxyribonucleic acid, DNA, is one of the four major biomolecules in living organisms. It is a polymer made up of monomers called NUCLEOTIDES. The nucleotides that make up a DNA molecule is composed of three substances namely: Sugar (deoxyribose), nitrogenous base, and a phosphate group.

However, among these three components of the nucleotide monomer, NITROGENOUS BASE is the only portion that is not the same in every DNA molecule. There are four nitrogenous bases in nature viz: Adenine, Guanine, Cytosine and Thymine. These four bases can be alternated in a DNA molecule.

Note that, phosphate group and deoxyribose sugar are constant in every DNA.

Which biological scenario(s) best describes phenotypic plasticity for a trait?
DIA [1.3K]

Answer:

C) II and III only

Explanation:

Option 1 is not an example of phenotypic plasticity because each person is born with their own blood type and this doesn't change based on their environment and behavior.

Option 2 is an example of phenotypic plasticity because a person's red blood cell counts can increase based on their environment, i.e. moving to Denver, CO from Death Valley, CA. The higher elevation and decreased oxygen causes your body to produce more red blood cells.

Option 3 is an example of phenotypic plasticity because one twin can be taller than another because of differing behaviors, environments, etc.

How are traits passed down to you from your parents
enyata [817]
Through crossing over during meiosis. In eukaryotic cells (us), there are these things called Histone proteins. TONS of these wrap around and form what eventually will be a chromosome in the nucleus of the cell. These chromosomes contain genes which contain genetic information in the form of DNA. If a trait is sex linked it will pass through to the offspring by meiosis, specifically during crossing over when homologous chromosomes exchange genetic information.
