What is the relationship between genetic variation and the ability of a population to withstand a changing environment?

1 answer:

8 0

Genetic diversity serves as a way for populations to adapt to changing environments. With more variation, it is more likely that some individuals in a population will possess variations of alleles that are suited for the environment. Those individuals are more likely to survive to produce offspring bearing that allele.

Answer:

Vaccine for Measles, Mumps, Rubella, Varicella should be delayed.

Explanation:

Generally IVIG usually inhibit the immune response, to the live pathogen used to induce response in the vaccine.Consequently, given another vaccine immediately may have adverse effect on the immune system of the child. Therefore a period of intervals should be set between administration of IVIG and other vaccines.

Based on standard recommendation; this depends on the nature of vaccine the child needs.Thus if

mihalych1998 [28]

Answer:

The correct answer is - The cell walls of archaea lack peptidoglycan.

Explanation:

Archaea are the prokaryotes that are different from bacteria in various ways but the most important differences are the membrane lipids and the major component of the cell wall that lacks peptidoglycan found in the cell wall of bacteria.

These prokaryotes are able to use carbon dioxide to oxidize hydrogen, releasing methane. Archaea-like prokaryotes have a high level or complex genetic diversity.

What does the theory of natural selection state

Daniel [21]

Answer:

The theory of natural selection was proposed by Charles Darwin, which states the mechanism of biological evolution by explaining adaptation and speciation. There was five observation of the theory of natural selection.

1) The population produces more offspring than there are adults, in each generation.

2) The population does not continue to grow in size.

3) Food and many other resources are limited.

These three observations interfere that individuals compete for resources within a population.

4) Individuals within all populations vary.

5) Many variations are heritable.

He also assumed from these two observations that individuals inherit some characteristics that give a better chance of surviving and reproducing.

These observations and interpretations helped him to propose the theory of natural selection. The theory tells the heritable characteristics in a population change over time become more adapted in generation after generations.
