G6PD deficiency is an inherited condition in which the body doesn't have enough of the enzyme glucose-6-phosphate dehydrogenase niece or G6PD which helps red blood cells function normally. G6PD deficiency is most common in African-American males. When females are carries. It is known to Africa in the Mediterranean basin are high risk areas for the infectious disease malaria. Researchers have found evidence that the fair site that causes malaria does not survive well in G6PD deficient cells. How do you explain this

Answers

Answer:

The environment is not favorable for malarial parasite.

Explanation:

The malaria does not survive well in G6PD deficient cells because the malarial parasite named plasmodium needs blood cells for its survival but in G6PD deficient cells, red blood cells does not perform their function normally which make environment unfavorable for the malarial parasite so that's why we can say that malaria does not survive well in G6PD deficient cells.

A. Pairing of homologous chromosomes

B. Movement of chromosomes towards the metaphase plate

C. Condensation of chromosomes

D. Loss of the nuclear membrane

The correct answer is A. Pairing of homologous chromosomes

Explanation:

Mitosis and meiosis are two different forms of cell division in eukaryotic cells, those that have a nucleus.In meiosis in Prophase I: homologous chromosomes pair up and exchange genetic material by crossing over. In mitosis in Prophase I: genetic material begins to condense and form long, thin strands. The mitotic spindle is formed.During the cell cycle, the eukaryotic cell undergoes a series of changes that lead to the formation of new cells. Depending on the type of cell, it can divide by mitosis or meiosis.

Why are plains landscapes more likely to form meandering rivers than mountain landscapes

Answers

Explanation:

First, what are meandering rivers? Put simply they are rivers that flow in a zig-zag shape across the landscape. In other words, they curve in a back and forth manner.

On the mountain landscape, it is less likely for the rivers to curve back and forth because of the high elevation in the landform; which makes the back and forth shape pattern impossible, only a straight trajectory is possible.

Chances of having a child with blue eyes - 50%

Chances of having a child with brown eyes - 50%

Explanation:

Many of our traits are determined by our genetics. We inherit genetic information from both of our parents. From each of them, we get one copy of a gene that determines a certain trait. These gene copies are called alleles.

The dominant allele is the one that masks the effect of the other type of allele, called the recessive allele. This means that a person needs to have only one dominant allele in order for its effect to be expressed. In order for the effect of the recessive allele to be expressed, the person needs to have two recessive alleles.

If a man has blue eyes, which is a recessive trait, he needs to have two recessive alleles (bb). This is why the genotype of the man is bb.

If his child has blue eyes, this means that its genotype is bb as well. The mother's eyes are brown, which means that she needs to have at least one recessive allele. Based on this, we can conclude that her genotype is Bb.

Since the mother has one dominant allele, this means that her children could have brown eyes as well. This is what the Punnett square would look like:

    B       b

b   Bb    bb

b   Bb    bb

Two out of four children would have brown eyes, and the other two would have blue eyes. This means that their chances of them having a child with blue eyes are 50%. The chances of them having a child with brown eyes are the same.

Answers

Answer:

She would mostly see plants grow around the banks of the lake. In addition, she might see some plants growing in the lake. The plants are majorly aquatic plants. The ones on the banks are emergent plants because their roots are submerged in water and their foliage is above water. They grow on the shores because it shallow there. Free-floating aquatic plants may grow in the lake because they are suspended on the water surface with their roots just floating underneath the water surface.
