Flow of individuals in and out of a population introduces new alleles and increase genetic variation within that population. Mutations: changes to an organisms DNA that create diversity within a population by introducing new alleles.
Answer:
Evaporation and Transpiration
Explanation:
Evaporation is the process in which water from bodies of water vaporizes and enters the atmosphere while transpiration is the process in which water from plants evaporates into the atmosphere.
The water cycle/h2o cycle
Answer:
Disruptive selection
Explanation:
Disruptive selection, also known as diversifying selection, describes changes in population genetics where extreme values for a trait are favored over intermediate values. In this case, the variance of the trait increases and the population is divided into two distinct groups. In this more individuals acquire peripheral character value at both ends of the distribution curve.
<h2>Mutation will occur </h2>
Explanation:
Base excision repair operates for small DNA damage such as deaminated bases
- DNA glycosylase plays an important role in cleavage of glycosidic bond of abnormal base (does not cleave phosphodiester bond)
- Uracil is incorrectly paired with guanine then mutation will occur
- The original GC base pair will change into AT base pair(transition of GC to AT)
- Transition is a mutation in which one purine(adenine or guanine) is substituted for other or one pyrimidine(cytosine or thymine or uracil) is substituted for other
