I think the cytoplasm keeps the cell solid.

Explanation:

Cytoplasm keeps all the cellular organelles suspended. The cytoplasm helps to keep them in place. It is also the site of most metabolic activities in the cell, and it allows materials to pass easily throughout the cell.

The cytoplasm is the liquid that keeps the cell solid. The correct option is C.

The cytoplasm is a liquid that is filled inside the cell. Between the cell membrane and the nucleus, there is a jelly-like fluid called cytoplasm. It facilitates material exchange and storage among cell organelles.

Cytoplasm helps the cell to stay still and rigid. It places all the cell organelle into a fixed place and the transfer of ions and molecules is also done by the cytoplasm. It is made up of water, salts, and other various material.

They help in the coming in of the materials and going out of the materials. They also protect the cell from shock and other invasive, they make the cell rigid and flexible and also protect recall from each other.

Thus, the correct option is C. solid.

ANSWER:

Voluntary muscles are those muscles which work under our conscious control and can be controlled at will also we can choose choose them when to use and when not to use. These are simply SKELETAL MUSCLES attached to the bone, so all the movements of hand and legs and whatever u do are because of voluntary muscles.

the muscles in the human body that do not work under our will and we cant control them. They are mainly controlled by the autonomic nervous system in the body. So, involuntary muscles include all the muscles whose activity which is not controlled by our NERVES. They are also called SMOOTH MUSCLES since they are present as the visceral layer over the organs.

1)      VOLUNTARY MUSCLES are under our control but INVOLUNTARY                 MUSCLES are not under our control

2)      VOLUNTARY MUSCLES are also known as skeletal muscles but INVOLUNTARY MUSCLES are also known as smooth muscles

3)      VOLUNTARY MUSCLES are attached to the bones in the body, but INVOLUNTARY MUSCLES are attached to the soft hollow internal organs.

4)      VOLUNTARY MUSCLES are controlled by the somatic nervous system. INVOLUNTARY MUSCLES are controlled by the autonomic nervous system.

5)      VOLUNTARY MSUCLES  require more energy. INVOLUNTARY MUSCLES require less energy.

Answer:

0.2um

Explanation:

take each of the answers multiply by 40 and see which the answer is 8um

0.2×40=8um

The diameter of the bacterial; cell would be 0.02 micrometer therefore the correct answer is option A.

It is defined as the multiplication factor used for the design of an object with respect to some other object. the scale is generally used to design prototype designs of large objects.

It is multiplied by the design dimension to get the actual size of the object or product.

As given in the problem A red blood cell is 8 micrometers in diameter. If a bacterial cell is 40 times smaller, then we have to calculate and calculate the diameter of the bacterial cell.

scale factor = 40

diameter of the bacterial cell = 8 micrometers/40

                                                 = 0.02 micrometers

Thus, the correct answer is option A.

The one that is not one of the four systems into which scientists divide earth is hemisphere. The correct option is B.

The four main subsystems of the Earth are the land, the water, the living beings, and the air. The term "spheres" refers to these four subsystems.

They are the "geosphere" (land), "hydrosphere" (water), "biosphere" (life) and "atmosphere," specifically (air).

The biosphere, geosphere, hydrosphere, and atmosphere are the spheres. Together, they are in charge of establishing and preserving the Earth's climate, geological processes, and life.

The main significance of the hydrosphere is that it supports a variety of life forms, is crucial to ecosystems, and regulates the atmosphere. All of the water on the Earth's surface is covered by the hydrosphere.

Thus, the correct option is B.
