Answer:

A protein molecule present in the RBCs, which helps in the transportation of oxygen from the lungs to the different parts of the body and brings back carbon dioxide, that is, collected from different parts of the body back to the lungs is known as hemoglobin.

The general features of hemoglobin are that it comprises four molecules of protein in the form of globulin chains. In adults, the molecules of hemoglobin comprise two beta-globulin chains and two alpha globulin chains, while in infants and fetuses, the beta chains are least found, and is substituted by two gamma chains.

Each globulin chain comprises an essential iron-containing compound porphyrin, which is termed as heme. Together both iron and heme play an essential role in circulating oxygen and carbon dioxide in the blood. This iron gives the red appearance to the blood.

If the current population size of bison is 3,652 and the maximum growth rate of the population is 0.28, calculate the population

s344n2d4d5 [400]

Given:

Present population of bison = 3652

Maximum growth rate = 0.28

To find:

The population of bison after one year.

Solution:

The future population can be calculated with the help of the following formula,

$P_F=P_P\times(1+r)^n$

where $P_F$ is the future population, $P_P$ is the present population, r is the growth rate and n is the number of years.

On substituting the given values in the formula we get,

$\Rightarrow P_F=3652\times(1+0.28)^1$

$\Rightarrow P_F=3652\times1.28\rightarrow4674.56\approx4675$

Therefore, the population size of bison after one year is 4675. The park does not have to control the population because the growth rate is on an average scale.
