Answer:

Solid 1 has the smallest amount of plasma membrane per volume of cytoplasm

<em>Note: The question is incomplete. The attachment below gives the complete question</em>

Explanation:

The outermost surface of a cell is bounded by the plasma membrane which functions to maintain the integrity of the cell as well as control the movement of particles in and out of the cell.

The ratio of the surface area of a cell to the volume of the cell indicates how big the cell is. When the surface area to volume ratio is small, the cell is very big, but if the surface area to volume ratio is big, the cell is small.

From the attachment below, the surface area (plasma membrane) per volume of plasma of the rectangular solids are as follows:

Solid 1: 10/2 = 5 cm⁻¹

Solid 2: 12.18/2 = 6.09 cm⁻¹

Solid 3: 19.0/2 = 9.5 cm⁻¹

Solid 4: 34.24/2 = 17.12 cm⁻¹

Solid 5: 65.79/2 = 32.895 cm⁻¹

Solid 1 has the smallest amount of plasma membrane per volume of cytoplasm

How does a cow use the sugar molecules stored in the grass it eats?

11111nata11111 [884]

ANSWER: A living organism intakes food, it breaks down into mostly water and large organic molecules. These large organic molecules are Fat, Proteins, Glucose, Starch and Cellulose. These molecules are still not usable by the cells so the body breaks these large polymers into small monomers.

In cow's muscles, protein muscles are built by tapping 4 amino acid monomers. Fat muscles are built by tapping 3 fatty acid monomers and 1 glycerol molecule.

Cows use glucose molecules to mix with oxygen to release chemical energy in cellular respiration. Cows can make fat molecules and glucose molecules because fatty acids and glycerols are made up of same atoms, C, H and O.

BOTH acids and bases A) turn red litmus blue. Eliminate B) are a component of soaps C) donate protons to solution. D) conduct el

Alecsey [184]

C is incorrect

Both acids and bases produce ions in solution, are electrolytes, and conduct electricity in solution. Although red litmus is an indicator, it does not change color in an acid, acids are proton donors while bases are proton acceptors. Soaps often contain bases, not acids.

D) conduct electricity in water. is the correct answer

spin [16.1K]

Answer:

p53 gene is an important gene that regulates the proper functioning of the cell. This gene plays an important role in the cell cycle progression and acts as genome guardian.

Any mutation in p53 leads to the formation of the different types of cancer cells. The p53 gene is activated by teh phosphorylation at the particular sites. High levels of phosphorylated p53 in the cell indicates that the cells DNA is highly damaged and mutated.

Water is essential for survival. It is important to understand the factors that affect water balance and the best sources to hel

Ludmilka [50]

Answer:

2-Water helps maintain body temperature.

3-Diuretics like alcohol and some medications can cause the body to lose water.

Explanation:

Dehydration occurs when the amount of what loss is more than the amount taken. And we lose water in many ways therefore taking water on a regular basis is important to replace the fluids lost and keep the body functioning.

Water Maintains the Body Temperature

During high temperature, the body cools itself naturally by sweating and by sweating a large amount of water is lost. So when enough water is not taken, there will be less production of sweating thereby causing the body's temperature to rise.

Alcohol Causes Water Loss

Taking excess alcohol can result to dehydration because the hormone called anti-diuretic (while alcohol is diuretic) is used to reabsorb water by the body and alcohol in the body depletes the production of this hormone. The body loses more water than normal with a reduced amount of anti-diuretic in the body. Excessive intake of alcohol can also cause vomiting, which depletes the body of fluids and can cause further dehydration.
