The body fluid of sharks has a much lower concentration of sodium chloride than that of the surrounding seawater, and sharks are able to remain in osmotic equilibrium with the external environment. Sharks store enough urea to match the total solute concentration of the surrounding seawater

An osmoconformer's internal bodily fluids are best described as having about the same total solute concentration as the surrounding environment. The sharks may use their amazing capacity to absorb ammonia to increase their urea reserves. The fish, which are scavengers, frequently go extended periods without eating, depriving themselves of the raw protein source necessary to keep their tissues' urea levels at a healthy level.

Since the two individuals are heterozygous, the genotypes they will have for freckles will be Ff for each. The probability of having a child with freckles will be 75%.

Heterozygous refers to the presence of two different forms of the allele for a trait. These two different alleles are actually the contrasting forms of a gene. For example, the trait height can have two contrasting alleles one for tall and one for dwarf.

Genotype refers to the genetic make-up or constitution of an organism. This genetic constitution can be for the entire genome or for any particular trait. The genotype also provides insight about the allelic combinations.

The seven characteristics of living beings: MRS.GREN

What is mrs.gren?

All living beings have some characteristics that they perform that deem them living being. These characteristics are how living and non living beings are differentiated.

The term MRS.GREN is used to recall the seven characteristics;

M- (movement) all living things have wide range of movements.

R- (reproduction) reproduction is a way that living things used to produce new organisms of their kind.

S- (respiration) In most living things, oxygen is used to oxidize nutrients and CO2 is produced as a result of such.

G-(growth/develop) young living things grow and develop into adults.

R-(responsiveness) Living beings respond to their surroundings in a way non living beings do not. They are sensitive to light, heat and all the changes that occur around them.

E-(excretion) All metabolic waste and non useful wastes are eliminated from the body of an organism in this process.

N- (need/ nutrition) all living things need nutrients to survive and function on a daily basis.

In the following map, the highest recombination is seen between the E and G genes. They have the highest gene distance between them, which is 12 map units. The last option is the correct answer.

Recombination between two genes takes place when there is enough distance between them for the genes to cross over. More is the distance, more is the chance, and less is the distance, less is the chance. When two genes are close to each other and don't allow crossing over, they are called "completely linked gene". Due to recombination, the variation is seen in the offspring. The crossing takes place during the pachytene stage of prophase I of meiosis.

Hence, the correct answer is the last option, as the maximum distance between E and G is seen, which is 12 map units.

Conversion of dihydroxyacetone phosphate in glycolysis requires glucose-6-phosphate to generate dihydroxyacetone phosphate. So the correct option is C.

Glycolysis is the process of forming pyruvate from the catabolism of glucose molecules. This process creates ATP, NADP, and FADH₂ molecules. The dihydroxyacetone phosphate (DHAP) reaction step involves the conversion of DHAP to glyceraldehyde-3-phosphate (G3P) by the enzyme triose phosphate isomerase. This enzyme catalyzes the isomerization of a tri-carbon sugar to another tri-carbon sugar (G3P).

Dihydroxyacetone phosphate is in the glycolytic pathway and, along with glyceraldehyde-3-phosphate, is one of two products formed when fructose-1,6-bisphosphate is broken down. It is readily and reversibly isomerized to glyceraldehyde-3-phosphate.

Answer:

How does mutation affect cell cycle? In most instances, the alteration of the DNA sequence will result in a less functional (or non-functional) protein. The result is detrimental to the cell and will likely prevent the cell from completing the cell cycle; however, the organism is not harmed because the mutation will not be carried forward.

Explanation:

The menstrual cycle begins with a change in hormonal level and maintaining the endometrial lining of the uterus.

The endometrial lining is a breakdown, and low levels of estrogen cause to stimulate the pituitary to release FSH and LH, this hormone stimulateing follicles for developing oocytes to produce estrogen.

When estrogen level is at a peak, suppresses FSH production and develops other follicles, a gradual increase in LH causes the follicle to rupture then high progesterone levels maintain the endometrial lining.
