Cells divide for many reasons. For example, when you skin your knee, cells divide to replace old, dead, or damaged cells. ... When organisms grow, it isn't because cells are getting larger. Organisms grow because cells are dividing to produce more and more cells.

Answer:

Explanation:

Cells in an organism go through division all the time. One reason is for growth. As an organism grows, more cells are created. Cells divide instead of grow because there is an optimal size for cell. So it is more efficient to create new cells.

Second reason for cell division is to repair damaged cells. Some cells like skin cells are damaged routinely and cell division is the way to repair and replace damaged cells.

Last reason is for reproduction. All organisms use cell division to reproduce.

Answer:

Soil erosion.

Explanation:

Soil erosion is the impact of floods on ecosystems because the floods moves very fast which takes soil with itself. Due to soil erosion, the productive layer of the soil or the layer in which nutrients are present are eroded which has a negative impact on the plants due to unavailability of nutrients. The floods moves very fast and the soil has no the ability to hold its particle tightly which leads to erosion of the soil that negatively affected the ecosystem.

True, the complementary base strand to the DNA sequence ATGGCTA is TACCGAT, hence option A is correct.

Deoxyribonucleic acid, or DNA, is a kind of genetic material. The polynucleotide chain is very lengthy.

Deoxyribose sugar (a molecule containing carbon), phosphate group, and nitrogenous bases make up each nucleotide (nitrogen-containing compound).

There are two types of nitrogenous bases: pyrimidine and purines, which include adenine and guanine (consisting of Cytosine and Thymine). Guanine forms three hydrogen bonds with cytosine whereas Adenine couples with thymine through the formation of two hydrogen bonds.

Therefore, the complementary base strand to the DNA sequence ATGGCTA is TACCGAT, hence option A is correct.

Explanation:

If we are cutting down thousands of trees in just seconds, they still cannot grow back in a couple of seconds.

It takes months and years for them to grow back.

So we need to be mindful of our resources, even if they're renewable.

Answer: Girls need to inherit two affected chromosomes to develop the disease, and it may also happen that the affected chromosome is inactivated in the eye (if it has only one)

Explanation:

Norrie's disease is an inherited eye disorder affecting males, which is characterized by abnormal or immature development of the retina (light-sensitive nerve tissue lining the back of the eye) and possible deterioration of the iris (colored part of the eye) and eyeballs. X-linked recessive inheritance is one of the ways in which a genetic trait or condition is passed from parent to child when there are mutations in a gene on the X chromosome from either the father or the mother. Females possess two X chromosomes, while males possess one X and one Y chromosome. In males, the presence of a mutation on the X chromosome causes the disease, since it is the only X they possess. In females, both X chromosomes need to be affected if it is a recessive condition.

So, the disease is inherited in an X-linked recessive manner, which means that almost all affected individuals are male. However, the sons of affected males will not have the mutation since they only inherit the Y chromosome, while all their daughters will be genetic carriers of the mutation because they inherit the affected X chromosome, although without clinical symptoms but being carriers. On the other hand, the mother will pass one of her two X chromosomes (which may or may not be affected) randomly to both her male and female offspring (if they are male, they will be affected and if they are female they will be carriers unless they also inherit an X chromosome from their father). So the only way for females to develop the disease is for their two copies of the gene to be mutated if both parents have the mutation.

But female carriers could be affected by inactivation of their X chromosome with the correct sequence. X chromosome inactivation is a random process that happens separately in individual cells during embryonic development. That is, one cell may inactivate the paternal X chromosome, while others may inactivate the maternal X chromosome. This is because a dosage compensation is necessary, since the Y chromosome in males is not homologous to the X, it does not have the same genes, so if females would express both X chromosomes, they would have twice as many genes as a male.  All the descendant cells of each of these original cells will maintain the same pattern of X chromosome inactivation.

In females, one X chromosome is inactivated in each tissue in an arbitrary manner. Then, in addition to having to inherit two affected chromosomes, it may also happen that the affected chromosome is inactivated in the eye (if it has only one).
