Answer:

She could time how long it takes for each amount of salt dissolves in the waters. (as well as keep each amount of salt the same if she was not doing that already.)

Explanation:

This way, she could observe which water is best for dissolving solvents and which is most affective in the shortest amount of time. If she was not timing how long it takes for salt to dissolve in different temperatures of water, then the experiment may as well have been useless unless there is somehow a different objective.

Gene control mechanisms, or "gene expression," control _____.
Luda [366]

Answer:

I believe the  correct answer is<em> </em><u><em>C. mRnA translation. </em></u>

Explanation:

Because the gene expression is controlled on two levels. First, transcription is controlled by limiting the amount of mRNA that is produced from a particular gene. The second level of control is through post-transcriptional events that regulate the translation of mRNA into proteins.

Which three of the following entities are acellular?.
arsen [322]

Answer:

Prions archea, viroids bacteria, viruses protists are acellular while fungi is cellular.

While viruses have indeed been closely researched for more than a century for infections of people and animals, most viruses, particularly those that infect microorganisms, are still poorly understood. 

Pathogenic RNA molecules are known as viroids. Contagious protein particles are identified as prions. Viruses are larger than that of viroids. Viroids are larger than prions in size.

Molds, wild yeasts, as well as mushrooms are examples of fungi. Numerous fungi are multicellular and also have nuclei in their cells. A protein-encased DNA or RNA core defines viruses being non - cellular organisms. Some scientists disagree with the notion that viruses are living things.

The space shuttle Endeavor is launched to altitude of 500,000 m above the surface of the earth. The shuttle travels at an averag
Marianna [84]

Answer:

Time taken by space shuttle = 714.28 m/s

Explanation:

Given:

Distance cover by space shuttle = 500,000 meter

Speed of space shuttle = 700 m/s

Find:

Time taken by space shuttle

Computation:

Time taken = Distance / Speed

Time taken by space shuttle = Distance cover by space shuttle / Speed of space shuttle

Time taken by space shuttle = 500,000 / 700

Time taken by space shuttle = 714.28 m/s

1. The sensory layer of the eye.
Keith_Richards [23]

Answer:

The correct answers are:

1. The sensory layer of the eye. B) Retina

2. The structure most responsible for focusing light rays that enter the eye. D) Lens

3. Helps maintain the intraocular pressure; located in the anterior part of the eye. A) Aqueous humor

4. Area of greatest visual acuity. C) Fovea centralis

Explanation:

1. The sensory layer of the eye.

The retina covers the inside of the eyeball. It is considered as the sensory organ of the eye, where the perceived images are projected, are processed in the form of a nerve impulse that leaves the optic nerve.

2. The structure most responsible for focusing light rays that enter the eye.

The lens are the transparent structure inside the eye that focuses light rays in the central part of the retina.

3. Helps maintain the intraocular pressure; located in the anterior part of the eye.

The aqueous humor, is a transparent aqueous fluid secreted by the ciliary body, this liquid derived from the blood plasma, distributes oxygen and nutrients to the upper part of the eye and eliminates residual products. The dynamics of production and elimination of aqueous humor is very important to keep intraocular pressure (IOP) within normal limits.

4. Area of greatest visual acuity.

The fovea, or also known fovea centralis, is the center of the visual field, it is a narrow area of the retina that only contains cones. Its function is to help us have a vision as clear as possible with all kinds of details and precision.
