( I NEED THE ANSWER ASAP PLEASE!).
A population of rodents lives in one species of pine tree. They have a commensalistic
relationship with the tree; they use it for protection & housing & the tree is not affected. These
pine trees have very evenly spaced branches of uniform thickness. Rodents that are too small
cannot reach between the branches to move around in the tree. Rodents that are too big and
heavy break through the branches and fall out of the trees. The rodent population that is very
uniform in size have become more populous.

9) Explain how this is related to natural selection. Make sure to include a cause and an effect
within your explanation.
a) How is this related to Natural Selection? (2 points)

b)What has caused the mice population to shift to uniform sized mice? (1 point)

c)What is the effect of this population shift?(1 POINT)

Answers

Answer 1

Answer: I’m not sure but it relates to natural selection because the rodents depend on the tree for survival and the tree is neither harmed or benefited from the rodents the cause and affect is the rodents stay in the tree and the tree is neither harmed or benifited. Pls do not rely on my answer I’m just saying what I think

Answer:

Most tissues of the body grow by increasing their cell number, but this growth is highly regulated to maintain a balance between different tissues. In adults most cell division is involved in tissue renewal rather than growth, many types of cells undergoing continuous replacement.

Explanation:

Internal monitors called checkpoints track each step of the cell cycle. In the cell cycle, there are three main checkpoints; one at the end of G1, a second at the transition of G2/M, and a third during the metaphase. Positive molecules of the regulator allow the cell cycle to proceed to the next level.

Mitosis, although continuous process, is conventionally divided into five stages: prophase, prophase, metaphase, anaphase and telophase.

Which type of reproduction is responsible for genetic variation?

Answers

Answer:

sexual reproduction

Explanation:

Sexual reproduction results in infinite possibilities of genetic variation. In other words, sexual reproduction results in offspring that are genetically unique. They differ from both parents and also from each other.

Other reproductions like asexual, budding or fragmentation don't produce genetic variation.

The type of reproduction is responsible for genetic variation is - sexual reproduction.

Sexual reproduction is combining genetic information from two individuals, by the fusion of gametes such as sperm and egg, called fertilization which generates more genetic variation, by the process like the combination of alleles and crossing over.

Parents and offsprings are not identical in this reproduction type, however, they are genetically similar.Fusion or combination of two different parent's gametes.There is recombination take place which causes genetic variations as well.

Thus, the correct answer that is responsible for genetic variation is - sexual reproduction.

if the egg of a particular butterfly has 14 chromosomes, how many chromosomes will be found in a somatic cell for this butterfly - PLEASE HELP DUE TONIGHT

Answers

Answer:

not

Explanation:

If the egg of a particular butterfly has 14 chromosome, then the somatic cells will have same 14 chromosomes.

What are somatic cells?

A somatic cell, also known as a vegetal cell, is any biological cell other than a gamete, germ cell, gametocyte, or undifferentiated stem cell that forms the body of a multicellular organism.

These cells make up the body of an organism and divide via binary fission and mitotic division.

Mitosis is a cell division process that produces somatic cells. They have two copies of each chromosome, one from the mother and one from the father. Diploid cells usually have two copies each of each chromosome.

Mitosis is the method by which one cell splits into two genetically identical daughter cells.

The cell's chromosomes are copied and then distributed evenly between the two new nuclei of the daughter cells during the various stages of mitosis.

Thus, as these are somatic cells, they will have same number of chromosomes.
