What are some nutrients necessary to sustain life that are cycled within a biosphere?

David is a collegiate track athlete, and his friend Tony is sedentary and overweight. At a party, they drink the same number of

dedylja [7]

Answer:

Option A

Explanation:

The rate and amount of decomposition of alcohol depends on the amount of body fat in an individual. The activity of enzyme alcohol dehydrogenase that breaks down alcohol is affected by concentration of body fat and water.

The higher the body fat and the lower is the body water and fluid, the higher is the activity of enzyme alcohol dehydrogenase.

Thus, the higher activity of enzyme alcohol dehydrogenase ensures higher rate of breakdown of alcohol due to which level of alcohol concentration in blood of an individual reduces.

Hence, option A is correct

Which of the statements are true? Yeast cells that produce more unsaturated fatty acids than saturated fatty acids in response t

Feliz [49]

Answer:1)Yeast cells that produce more unsaturated fatty acids than saturated fatty acids in response to cold have greater cold tolerance

2)Cell membranes in reindeer legs (near the hooves) are kept flexible because they have a large number of saturated fatty acids.

3.)Cell membranes in cold tolerant winter wheat plants have a higher ratio of unsaturated fatty acids to saturated fatty acids than do cold intolerant wheat varieties.

Explanation.

Basically the longer the chains of fatty acids the higher the degree of energy produced as heat energy, and therefore the higher the insulation.

Unsaturated fats clogged together and the aggregate carbons and hydrogens ensured insulation.

a. The logistic equation reflects the effect of density-dependent factors, which can ultimately stabilize populations around the

castortr0y [4]

Question:

Which of the following is an incorrect statement about the regulation of populations?

Answer:

b. Density-independent factors have an increasingly greater effect as a population's density increases.

Explanation:

A population can be defined as the total number of living organisms living together in a particular place and sharing certain characteristics in common.

Generally, these populations may be divided into a fraction of the population (subpopulation) based on certain factors and reasons.

Population change equation states that the change in the size of a population over a specific period of time is equal to the sum of the number of births and the number of immigrants that joined.

Mathematically, the population change equation is given by the formula;

Population Change = (Natality - Mortality) + (Immigration - Emigration)

Population regulation can be defined as a biological process that balances limiting factors affecting the growth of a population based on density. The factors that regulate the growth of a population are divided into two (2) main categories and these includes;

I. Density-independent factors.

II. Density-dependent factors.

Density-dependent are regulating factors such as predation, diseases, and competition that affect the size of the population of living organisms through decreasing or increasing mortality and birth rate.

Furthermore, density-independent factors do not have an increasingly greater effect as a population's density increases. Thus, its effect are reduced as a population's density increases in size.
