Changes in the DNA sequence, or mutations, help drive

Answers

Answer 1

Answer: The answer is evolutionary change.

A mutation is the alteration of a nucleotide sequence in DNA. If a mutation occurs in the genes that control development it will cause great effects on the adult organism. Since these effects are so significant, they will make some evolutionary changes.For example, a mutation could cause parents with genes for bright coloration to get offspring with genes for darker coloration. After a period of time, that darker coloration will be more frequent in the population than before, so it will cause large-scale evolutionary change.

Describe how mendel showed that the green-seed trait did not disappear but was only masked. Please help me :)

Answers

Mendel showed that the green-seed trait did not disappear but was only masked by breeding plants with only two alleles for the trait. After the cross of yellow seed, a small amount of offspring had green seeds. So, he concluded that the green-seed trait is masked by the dominant yellow-seed trait and that two alleles are necessary for green-seed trait to show up.

Explain how hypertension, heart disease, and stroke are related.

Answers

Hypertension, heart disease, and stoke are related because they all have to do with the heart. Hypertension is when you have high blood levels, heart disease is when your heart doesn't work properly, and stoke is when the heart beats hyperactively or the opposite.

Hypertension is another term for high blood pressure. This occurs when there is too much pressure put on the blood vessels. The heart gets affected because it is pumping against the pressure, which causes strain on the heart. This can cause thickening of the heart walls, which can lead to other heart problems.

Stroke occurs when there blood supply to the brain is reduced or obstructed. This deprives the brain of oxygen and other nutrients. The occurrence of stroke increases with blood pressure because there is persistent pressure on the vessels which can ultimately lead to stroke.
