I need help with one paragraph.

Answer:

The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.

A proton gradient is a difference in the concentration of protons (H+) across a membrane. In cellular respiration, a proton gradient is created by the electron transport chain (ETC) in the mitochondria.

The ETC is a series of proteins that shuttle electrons from NADH and FADH2 to oxygen. As the electrons are shuttled, they lose energy, which is used to pump protons out of the mitochondrial matrix into the intermembrane space.

This creates a concentration gradient, with more protons in the intermembrane space than in the mitochondrial matrix.

The proton gradient is used to power ATP synthesis. The enzyme ATP synthase, which is located in the inner mitochondrial membrane, uses the energy of the proton gradient to drive the synthesis of ATP from ADP and inorganic phosphate (Pi).

The proton gradient is a key part of cellular respiration, and it is essential for the production of ATP. Without the proton gradient, ATP synthesis would not be possible, and cells would not be able to produce the energy they need to function.

Answer: At low latitudes, near the equator, direct overhead sunlight received all year warms surface waters.

Cold water is also more dense, and as a result heavier, than warm water. Colder water sinks below the warm water at the surface, which contributes to the coldness of the deep ocean.

Explanation:

Answer:

The density of ocean water is so varied, that while there may be a generally considered variation due to temperature, taking random samples in a wide variety of places, thus you can distinguish no real pattern.

Explanation:

Answer:

During metaphase II, the centromeres of the paired chromatids align along the equatorial plate in both cells. Then in anaphase II, the chromosomes separate at the centromeres. The spindle fibers pull the separated chromosomes toward each pole of the cell.

Meiosis and mitosis are forms of cell divisions that occurs in cells in eukaryotes. This forms of division enables growth and development.

The major way meiosis ii differ from mitosis is that in meiosis II, the daughter cells formed are haploid cells.

Mitosis is also termed as an equational division meaning that the end result yields the same number as the beginning, there is no reduction and resulting cells are still diploid.

In meiosis, there is the reduction in half first in meiosis I then the homologous chromosomes separates at the centromeres in meiosis II resulting in haploid cells.

Answer:

It is Testosterone

Explanation:

The hormone responsible for the development of the male secondary sex characteristics is testosterone. Hence option D is correct.

Testosterone is a hormone primarily produced in the testes of males and to a lesser extent in the ovaries of females and the adrenal glands of both sexes. It is an androgen, or a hormone that promotes the development of male characteristics.

Testosterone plays a crucial role in the development of male reproductive tissues, such as the testes and prostate, as well as in the growth of muscle mass and bone density.

It is also responsible for the development of secondary sex characteristics in males, such as facial hair growth, a deepening of the voice, and the growth of Adam's apple. Testosterone also regulates sex drive (libido) and sperm production.

In females, testosterone is produced in smaller amounts and helps regulate the menstrual cycle and promote bone density.

An imbalance of testosterone levels in either males or females can lead to various health issues, including infertility, osteoporosis, and disorders of sexual development.

Hence option D testosterone is correct.

A. Accurate but not precise

Step-by-step explanation:

The illustration given shows that the was far from each other which means it is not precise because precision is that the given data must be close to each other. However, it is accurate because the darts are closer to the bullseye which can still be considered as accurate. Therefore, I believe this is accurate but not precise.

The best description of this attempt is that the dart thrower is aiming to hit the center of the target.

A person who throws darts at a dartboard is known as a dart thrower. In the game of darts small missiles commonly referred to as darts are thrown at a circular target called a dartboard. Apart from being played in international competitions, the game is commonly played in bars or pubs. Each of the 20 numbered parts on a typical dartboard corresponds to a different score.

The goal of the game is to collect points by throwing darts at the board and hitting special spots to do so. The bullseye, located in the middle of the dartboard, awards the most points when hit. The popular sport and pastime requires precision, concentration and expertise.

Therefore, the best description of this attempt is that the dart thrower is aiming to hit the center of the target.
