The correct answer is B.
Meiosis is the process which accounts for species diversity. Meiosis is termed as a specialized cell division which reduces chromosomes number by half and then creates for haploid cells.
The process of meiosis occurs in multicellular eukaryotes and in sexually reproducing single-celled. For example plants, fungi, and animals. The two meiotic divisions are called meiosis11 and meiosis 1.
Now that chromosomes are halved during meiosis gametes can fertilize to form a diploid zygote and contains two copies of chromosome one from each other.

b) Meiosis) accounts for species diversity. Meiosis results in four rather than two daughter cells, each with a haploid set of chromosomes. Meiosis is responsible for producing gametes or sex cells.

The nonselective, passive process performed by the glomerulus that forms blood plasma without blood proteins is called ________.

shutvik [7]

The nonselective, passive process performed by the glomerulus that forms blood plasma without blood proteins is called filtration.
Glomerular filtration is the first step in making urine which includes the separation of the liquid part of the blood (plasma) from the blood cells. Glomerulus of the kidneys (a tuft of blood capillaries) filters excess fluid and waste products out of the blood into the urine collecting tubules of the kidney and thus eliminates it out of the body.

How does sprinting

Vsevolod [243]

Explanation:

Much energy is demanded within a short period in a sprint as opposed to long-distance that mainly demands stamina. During sprints, therefore, the energy demands by the muscles my outpace the supply by energy because oxygen is not reaching fast enough for aerobic cellular respiration. This is why sprinting cannot be sustained for long without accumulation of lactic acid in muscles – due to glycolysis metabolisms being the main source of energy.

IN long substance however, the runner does not sprint the entire marathon but run at sustainable speeds allowing the energy demands by the muscles to be met by the more effective aerobic respiration

This diagram shows the menstrual cycle.

LiRa [457]

Answer:

According to the hormone diagram of the menstrual cycle, the woman is not pregnant due to the behavior of progesterone and estrogens, whose levels do not increase, in addition to the absence of human chorionic gonadotropin.

Explanation:

The graph shows the behavior of hormones during a woman's menstrual cycle in the absence of pregnancy.

During a woman's normal cycle, estrogen, luteinizing hormone (LH) and follicle stimulating hormone (FSH) tend to increase prior to ovulation, reach their peak values at ovulation, and then decline, as shown in the graph. Progesterone, on the other hand, increases after ovulation and decreases if the woman does not become pregnant.

In the case of a pregnant woman:

Estrogens continue to increase after ovulation, produced by the ovaries and placenta.
Progesterone also increases its levels, as it is a hormone produced by the ovaries and placenta.
Hormone human chorionic gonadotropin (HCG) appears and increases during pregnancy, due to the secretory activity of the placenta.

The diagram represents the normal cycle of a woman who is not pregnant.

Membrane proteins are not soluble in water solutions. To purify and crystallize membrane proteins, the proteins need to be disso

katrin2010 [14]

Answer:

Detergents are knows as a class of molecules whose having unique properties to enable formation of hydrophobic-hydrophilic interaction among molecules in membrane. This unique property of detergents are used to dissolve membrane protein in water solution or in any solution.

Detergents are used to lyse cells, solubilize membrane lipids, and proteins, prevent protein crystalization, and nonspecific binding.
