Answer:

B. It is done by humans to select certain traits useful to us.

Explanation:

There are two main types of selection: natural and artificial. Natural selection is all of the other answers, it is seen over generations and allows the fittest to survive. It also occurs with no human intervention. However, artificial selection is done by humans. It occurs when humans breed animals to best fit their needs. This is best seen in dog breeding.

Answer:

the maximum population size that a particular environment can support.

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 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.

Carrying capacity is the maximum population size that a particular environment can support. The carrying capacity of an environment is denoted by the letter k.

What is the mass of an element with 15 protons, 13 electrons, and 11 neutrons?
RSB [31]

Answer:

B. 26amu

Explanation:

The nucleus of an atom in an element contains protons, electrons and neutrons. The proton number equals the electron number in a neutral atom. The proton number is also called the atomic number, denoted by Z.

The mass number also called Atomic mass unit (amu) in this case, of an element is the sum of the proton number and the neutron number in the atom of that element. The mass number is denoted by A.

Hence, A = Z + N

Where A = Mass number

Z = Proton (atomic number)

N = Neutron number

In this question, N is 11 while Z is 15

Hence, the mass number of the element in the question, in AMU, is 15 + 11 = 26amu.
