Answer:

control which substances enter the cell

Explanation:

According to this question, scientists in year 1800s studied how fat-soluble substances and water-soluble substances interact with cell membranes. Cell membrane is a cellular structure found in every living cell whose function is to demarcate the interior of the cell from the external environment.

Based on the study, cell membrane interacts with water-soluble and fat-soluble substances in order to control which substances can enter the cell. The cell membrane is selectively permeable meaning that not all substances passes through it into and out of the cell.

vitfil [10]

Answer:

The correct answer is:

which of the blood type forms when an individual receives one copy of each allele? (D)

Explanation:

Alleles are each of the alternative forms of a gene. In this example, the two forms of the alleles for the Rhesus (Rh) factor are Rh+ and Rh-. These alleles can either be expressed as h0m0zygous alleles (two of the same kind; Rh+ Rh+, Rh- Rh-) or heterozygous alleles (a pair made up of both; Rh+ Rh-)

In the h0m0zygous state, there is the expression of the allele that makes up the pair. However, in the heterozygous state, the dominant allele is expressed phenotypically, even in the presence of the recessive allele that makes up the genotype. Therefore, the dominant allele is the resulting blood group seen in an individual in a heterozygous (one copy of each) state.

When blood flow to the brain is interrupted, less oxygen and glucose reach the brain. This causes brain damage and neurological problems.

<h3>Blood flow to the brain</h3>

Blood circulation in the brain has an important function in maintaining brain health. Blood circulation provides the brain with the oxygen and nutrients it needs to function properly.

Blood carries oxygen and glucose to the brain. The brain makes up only a small part of your total body weight, but it requires a lot of energy to function. The brain uses about 15% of the oxygen and glucose the body needs. In short, blood flow to the brain is a very important factor in maintaining brain health. If this cycle is disrupted, the brain can be damaged. As a result, many diseases and disorders related to nerve function can occur.
