How does the contractile vacuole in a single-celled organism function to maintain homeostasis?

2 answers:

8 0

Answer: The contractile vacuole found in the single cell organism helps in the movement of water from inside to outside of the cell.

In case of single celled organism, the process of homeostasis is performed by the help of vacuoles.

When there is an excess of water inside the cell and there is an imbalance in the solute concentrations inside the cell.

In this case, vacuoles helps in pumping the water out of the cell. This is how homeostasis is maintained inside the cell.

Which BEST describes the orbit of the Moon around Earth?

Solnce55 [7]

The statement that best describes the moon's orbit around the Earth is <span>c. elliptical with a period of about one month. Although its orbit is elliptical, the moon's orbit can be described as nearly circular because it has an eccentricity of 0.05. Moreover, it takes around 27.322 days for it to orbit around the Earth once.</span>

Where is long-wavelength radiation created?

Ivahew [28]

On the earth surface

Explanation:

The long-wavelength radiation is created on the earth surface when electromagnetic radiation is re-emitted.

The sun releases radiation in form of short-wave.
They are usually more energetic and with short wavelength and a high frequency.
When they interact with materials on the earth, they are radiated back as long-wavelength radiation that usually causes heat.
Ultraviolet rays and other high energy waves are emitted from the sun because it is a very hot body.
When these radiations enters the earth, they are re-radiated back as long waves with lower energy.
Earth is cooler than the sun
When some of the short waves for example, the ultraviolet rays gets to the surface, it is absorbed and re-radiated back.
When the short waves are absorbed, they lose some of their their energy to the earth surface.
The remainder is radiated back as less energetic long waves.
The hotter a body is, the more energetic the radiation it releases.

The formation of the fertilization envelope (slow-block to polyspermy) requires an increase in the availability of _____.

jok3333 [9.3K]

<span>The formation of the fertilization envelope (slow-block to polyspermy) requires an increase in the availability of </span>calcium ions.

Slow-block to polyspermy is also called cortical reaction. In this reaction, the sperm will be permanently blocked by cortical granules. The release of calcium ion will trigger this reaction.

Genrish500 [490]

Answer:

releasing cytokines that will destroy the foreign cells.

Explanation:

Here is the complete question

A client's exposure to an infectious microorganism has stimulated the client's immune response, including activation of effector (cytotoxic) T cells. These cells will help to eliminate pathogens by:

releasing cytokines that will destroy the foreign cells.

stimulating B cells to become more immunologically active.

releasing antibodies from within their cells membrane.

initiating the inflammatory response.
