Gene flow and genetic drift are two factors that increase the genetic variation in a population.

Genetic variations are the changes or alterations which can occur in the sequence of gene of the DNA. These genetic variations are very necessary as they enable different living beings to evolve and also survive. There are two factors which can cause an increase in the genetic variation of a particular population and they are gene flow and genetic drift.

Gene flow can be defined as the movement of genes which occurs in and out of a specific population.  The in-flow of genes in a population can help increase the genetic variation of the individuals that are a part of that  population. Genetic drift is defined as the change in allelic frequency of a  population which occurs by chance. It brings about genetic variation.

The correct answer is A; 1%, alleles, A gene mutation is a change that occurs in one or more genes (myoo-TAY-shun). Certain genetic mutations can cause genetic disorders or illnesses.

The human genome is substantially same in all individuals. There are, however, variations across the genome. This genetic variety accounts for around 0.001% of each individual's DNA and results in differences in appearance and health. People who are closely related share more DNA.

There are genes that are dominant and recessive. The most common interaction between alleles is a dominant/recessive relationship. When one allele of a gene effectively overrules the other (recessive) allele, the dominant allele is said to exist. Correlations between dominant and recessive genes can be seen in eye color and blood type.

Rock fragments transported in a streambed are Sediment loads that are eroded by water(streams).

Streams are among the most powerful surface agents for eroding rock and sediment. Waterborne rock fragments, gravel, and sediment have an impact. The total amount of sediment transported is referred to as the load. The river has three types of sediment load: dissolved, suspended, and bed load.

When rock fragments carried by the swift current collide with bedrock channel walls, they knock off rock chips. Bedload particles follow the flow of water by sliding or bouncing along the bottom. The portion of sediment transport that rolls, slides, or bounces along the bottom of a waterway is referred to as bedload.

Acid precipitation is known to affect ecosystems that are located near the source of the pollution. This is because acid precipitation can be carried through the atmosphere and deposited in the surrounding areas, affecting the habitats and species that are found there.

By determining the distances between the source of the pollution and the ecosystem where the salamander was lost, it can be determined if acid precipitation was likely to be a factor in its loss. Data would also be needed on the types and concentrations of acids that are found in the air near the source of the pollution and the salamander's ecosystem, as well as the pH levels in both areas.

Which of the following types of data would be required in order to consider the hypothesis that acid precipitation caused the loss of the salamander?

A) sulfuric acid and nitric acid from the burning of fossil fuels are the major causes of acid precipitation.

B) larger organisms lost from freshwater ecosystems because of acidification may not return even decades after ph values have returned to normal.

Cell division is essential for growth and development of organisms. Cell division is regulated by the cell cycle, which consists of four phases: G1, S, G2, and M.

During G1, the cell grows and performs its normal activities. The S-phase is when the cell makes DNA. The cell gets ready to divide during G2. The cell divides into two daughter cells during the M-phase.

Occasionally, cells enter a resting phase called G0. This phase is characterized by the cell not actively growing and dividing. Cells in this phase are usually post-mitotic, meaning they are not planning to divide anymore and have exited the cell cycle.

Liver cells can divide and enter the cell cycle and produce new cells if the liver is damaged, up to 75%. This is possible because liver cells are bi-potent, meaning they have the potential to divide and create new liver cells. On the other hand, brain cells are post-mitotic and cannot enter the cell cycle and divide. Therefore, if the brain is damaged, it cannot produce new brain cells since they are not able to divide.

Answer: Your answer is option (A).

Explanation:

In a global convection cell the correct option is (C). Cool air and warm air repeatedly collide, pushing air up and causing storms.

In a convection cell, the alterations are profound. The air molecules start to move and vibrate as the air at the cell's base heats. As a result, they start to spread out and collide, which reduces the density of the air parcel.

Convection is a pattern that occurs on a large scale. On a smaller scale, it also takes place within certain storms. However, because to Earth's rotation, the air that travels north and south from the equator likewise revolves with the Earth. Northbound air makes a right turn. Southbound air turns to the left.

Less dense air rises and moves away from the equator in a global convection cell. And the dense air from the pole flows backwards toward the equator as it descends. The poles can be thought of as the longitudinal edges of the earth's sphere, with the equator acting as its centee. The Coriolis Effect, a result of the spinning of the Earth, also aids in this airflow.
