is this correct ? ...​

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.

Answer:

1. produces genetic variations.

2. produces resistance to unfavorable conditions.

3. produces disease-free seed plants.

Explanation:

Sexual reproduction causes more genetic variation. More genetic variation results in diverse immune systems and traits that are advantageous to survival. Variation is good because it allows a species to adapt to new environments.

The advantages of sexual reproduction is produces resistance to unfavorable conditions, produces genetic variations and produces disease-free seed plants.

Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete with a single set of chromosomes combines with another gamete to produce a zygote that develops into an organism composed of cells with two sets of chromosomes.

A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilised by sperm, and then the offspring develop.

Three mechanisms contribute to genetic variation arising from sexual reproduction: independent assortment of chromosomes, crossing over, and random fertilization.

The smooth endoplasmic reticulum is different from rough endoplasmic reticulum as the rough endoplasmic reticulum has ribosomes attached to its surface which are absent in smooth endoplasmic reticulum. Thus, the correct option is C.

Endoplasmic reticulum (ER) is a large, dynamic structure which serves for many roles in the cell. There are two types of ER which are Smooth Endoplasmic Reticulum (SER) and Rough Endoplasmic Reticulum (RER). The diverse functions of the ER are performed by distinct domains present in the ER consisting of tubules, sheets and the nuclear envelope.

Rough endoplasmic reticulum contains ribosomes on its surface and synthesizes protein, whereas the smooth endoplasmic reticulum does not contain ribosomes and functions to make lipids and detoxify the cell. Large amounts of SER are found in the cells which participate in lipid metabolism and detoxification of the body, such as liver cells.

Therefore, the correct option is C.

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.
