Answer: Epididymis

Explanation:

This is where the sperm matures at

Answer:

True

Explanation:

Answer:

Because Mercury  and Venus are too close to the Sun and its gravity.

Explanation:

Mercury and Venus do not have moons because of their proximity to the Sun and their specific orbital characteristics.

Both planets are located relatively close to the Sun, and their gravitational interaction with the Sun is strong.

Additionally, their orbits are relatively stable, which means that any small celestial bodies that might have approached them in the past were likely captured by the Sun's gravitational pull or flung out of the solar system.

Unlike outer planets such as Jupiter and Saturn, which have strong gravitational influences and numerous moons, the inner planets like Mercury and Venus have not been conducive to capturing or retaining moons due to their specific orbital dynamics.

Answer:

mitochondrion

Explanation:

The correct answer would be the mitochondrion.

The process of energy production in living organisms happens through oxidative phosphorylation during respiration. The process takes place in the mitochondrion. During respiration, glucose reacts with oxygen to produce carbon dioxide and water while ATP is generated in the process. The ATP represents the energy currency of the cell.

The entire process of respiration can be summarized by the following equation:

    [tex]C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + ATP[/tex]

1. The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction. Exceptions to this are the action of cilia, the flagellum on sperm cells, and amoeboid movement of some white blood cells.

2.

Skeletal: It is a form of striated muscle tissue which is under the voluntary control of the somatic nervous system. Most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons.

Smooth: composed of sheets or strands of smooth muscle cells. These cells have fibers of actin and myosin which run through the cell and are supported by a framework of other proteins.

Cardiac: It is an involuntary, striated muscle that constitutes the main tissue of the walls of the heart.

3. Voluntary muscles or striated muscles are those which work according to the one’s desire or are under control, whereas Involuntary muscles are not under one’s control. Biceps muscles, respiratory, alimentary and urogenital tracts are the places where voluntary muscles are found, while abdominal muscles, locomotory muscles, middle ear muscles, Diaphragm are the examples of the involuntary muscles.

4.

1st pic: Cardiac

2nd pic: smooth

3rd: Skeletal

5. Skeletal muscle is metabolically and mechanically maladapted to working as the muscle that causes the heart beat. The cardiac muscle has a much higher capacity to extract oxygen from the blood than any skeletal muscle with a higher mitochondrial density so the skeletal muscle heart would, at rest, be working at very near to its metabolic limits. This would not allow the body to do much exercise. The characteristics of skeletal muscle contraction are not the same as the characteristics of cardiac muscle contraction. Cardiac muscle is essentially a network of muscle fibers where most of the signal to contract is propagated by the fibers themselves and the contraction of the whole muscle occurs. The heart beat entails the whole heart contracting at a slower rate of contraction than skeletal muscle. I would conjecture that the relatively slow concentric beat of the whole heart would be better for pumping fluid than the more rapid beat of skeletal muscle. Nerves stimulate any number of motor units in skeletal muscle which, depending on how many nerves are activated, will allow fine gradations in muscle strength. This kind of control would not be necessary for the heart , so inefficient.

Answer:

1. Anaphase I

2. Anaphase II

3. Prophase I

4. Metaphase I

5. Metaphase II

6. Telophase I

7. Prophase II

8. cytokinesis

Explanation:

The first image or diagram shows that the chromosomes are pulled apart while sister chromatitds are attached to one another. This is took place in the anaphase I phase.

In second diagram the sister chrmoatids are become unattached and moves or pulled towards the opposite poles. It is Anaphase II stage.

In the third image or illustration there is formation of synapsis complex and chiasmata which takes place in prophase I.

In the fourth image the pair of chromosome lined up on the equator this characterstic feature of metaphase I.

In the fifth image sister chromatids are line up on the equator which is take place in metaphase II.

In the sixth image chromosomes reach on opposite ends and formation of nuclear envelope takes place which is take place in telophase I.

The seventh image is showing the condensation of chromosome and adestruction of nuclear envelope as occurs in the prophase II.

Formation of cells and divide into four individual cells is the process of cytokinesis.
