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

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.

A dip in the birthrate may slow down the growth rate, keeping immigration and emigration numbers equal. A constant death rate may also aid in slowing down the growth rate.

Further explanation:

Moving into a region is called as immigration and it is known to be a key facet in the growth of the populations. Emigration, on the other hand, refers to leave a demographic region. The populations gain people via births as well as immigration. They may lose people through emigration and deaths.

Population growth rate refers to how quick a population alters in size over a period of time. A growth rate if positive means that increase in number of individuals in a population whereas a negative growth rate shows that the population is decline. The 2 mina facets that affect the growth of the population are birth rate and death rate.

The population growth might be influenced by the individuals who are coming into the population or leaving the population

The formula for the population growth is:

 

Here,  

r= population growth rate

b=birth rate

i=immigration rate

d=death rate

e=emigration rate

When immigration and emigration are equal, then a drop-in birth rate and constant death rate may cause the decline growth rate of the population.

Explain how the data from the river samples showed that there was a problem with the water treatment plant.
Agata [3.3K]

Answer:

The water treatment plant does not work properly.

Explanation:

The data from the river samples showed that there was a problem with the water treatment plant because there is high amount of pollutants are present in the river sample. The presence of pollutants in the samples shows that the water treatment plant did not work properly, if they did no pollutants are present in the river water so this presence of pollutants indicates inefficiency of water treatment plant.

Biologic agents differ from other injurious agents in that they are able to replicate and can continue to produce their injuriou
Nostrana [21]

The question is incomplete as it does not have the options which are:

A. Gram-negative bacilli cannot cause harm to the cell; only Gram-positive bacilli can harm the cell.

B. Gram-negative bacilli release endotoxins that cause cell injury and increased capillary permeability.

C. Gram-negative bacilli excrete elaborate exotoxins that interfere with cellular production of ATP.

D. Gram-negative bacilli enter the cell and disrupt its ability to replicate.

Answer:

B. Gram-negative bacilli release endotoxins that cause cell injury and increased capillary permeability.

Explanation:

Gram-negative bacteria are pathogenic in nature due to the composition of their cell wall. Their cell wall contains an additional layer of a molecule called lipopolysaccharides or LPS.

The LPS layer is toxic in nature and is known as endotoxin and is involved in the pathogenicity of the bacteria as the toxin causes the injury to the Endothelial cell membrane of the host cell.  

When the bacteria cell is lysed and the LPS circulates in the blood, then LPS binds the receptors and acts on CD14. This attracts the neutrophils at the site and can cause vascular injury due to increased capillary permeability.

Thus, Option-B is the correct answer.
