Answer:

The correct answer is option C.

Explanation:

The exponential pattern of growth takes place in an ideal, unlimited environmental conditions, that is, where the resources are abundant. In such an environment, there exists no competition to restrict the geometric rate of growth. At the start, the growth of the population would be gradual, as there will be a lack of reproducing individuals.  

However, with the increase in population numbers, the rate of growth also increases, leading to the formation of an exponential curve. Exponential growth can be witnessed in the populations, which are very small or are confined in the areas that are newly established by a species.  

Thus, in the given question, the growth of the population of elephants, which is safeguarded from hunting and exhibits all the essential resources would be an ideal choice. As other examples, possess external factors affecting their growth. Though both bacteria and sparrow may reproduce at a greater rate, however, the population of elephants would develop at an exponential rate as the species are safeguarded.

If immigration and emigration numbers remain equal which of these could cause a slowed growth rate
rodikova [14]

Answer;

Decreased birthrate

If immigration and emigration numbers remain equal , decreased birthrate could cause a slowed growth rate.

Explanation;

All populations change in size with time . Change in population is dependent of various factors, namely; birthrates, death rates, immigration and emigration.

Therefore; change in population size would be given by the difference of the sum of birth rates and immigration and the sum of death rates and emigration. That is; Change in Population Size = (Births + Immigration) - (Deaths + Emigration). A decreased birth rate with emigration and immigration remaining constant would cause a slowed growth rate.

Answer:

In ecology, a biological interaction is the effect that a pair of organisms living together in a community have on each other. They can be either of the same species (intraspecific interactions), or of different species (interspecific interactions).

Answer:

C. Osmosis

Explanation:

Osmosis is the net movement of solvent molecules, usually water, from a region of lower solute concentration to a region of higher solute concentration through a partially permeable membrane. Osmosis is a very useful for moving materials in and out of the cell.

Solutions are mixtures of solutes and solvents. The main aim of osmosis is for all the mixture part to be uniform and the solvent equally dispersed to all the part of the solution.

Osmosis is controlled to a large extent by concentration gradient.

Diffusion on the otherhand is the movement of molecules of a substance from one position to another.

Facilitated diffusion and active transport are just mechanisms for transport within a cell or a body.

The plants that were allowed to self pollinate were the F1 plants.

The plants that are true breeding are P generation plants.

The plants where there were 3times as many tall plants as short plants are in F2 generation.

<h3><u>Explanation:</u></h3>

This question is based on the Mendel’s Experiment. Sir Gregor Johann Mendel was the father of genetics who experimented on garden pea plants <em>Pisum</em> <em>sativum</em> to see whether the characters got mixed or not and to know the real cause behind different traits of same character in plants.

He took the pure homozygous tall and short plants separately which he called as parental generation or P generation. These plants were homozygous, hence pure breeding.

As these plants were crossed between themselves, then the F1 generation showed all tall plants. This is because of the heterozygous plants which showed character of dominant trait. These plants were allowed to self pollinate.

As a result of self pollination of the F1 plants, the F2 plants were 75% tall in number whereas the other 25% short, which gave the phenotypic ratio of 3:1.
