Question

Which of the following is not the characteristic of the population?
A. Size
B. Density
C. Age distribution
D. Phenotype
E. Death rate

Answer 1

Population is a sum of all species of the very same group or species that live in a particular geographical area and therefore are capable of interbreeding. Population, in a simplified form, is the number of people in an area or town, nation, or world; the population is usually evaluated by a procedure called a census.

Complete Answer:
The phenotype is not really a defining characteristic of the population. It is a collection of measurable characteristics of a person arising from the interaction of the genotype with the ecosystem. Population size is the correct figure of people in the general population. Population density is the amount of overall population per unit area, i.e. population size split by total land area. Population density can alter due to natural or human-induced reasons. For instance, orangutan densities were found in mosaic habitats that faceless severe fruit scarcity compared with single habitat species. Differences exist not only among species, as well as between subspecies. Larger populations will be much more stable than tiny populations because they are likely to experience larger genetic variation and therefore more prepared to cope with changes in the climate by natural selection. The distribution of age is a prominent feature of a population. Statisticians widely use population pyramids to define population distributions both for age and sex. Each bar in a pyramid is divided into segments relating to the proportion of men and women. In most population groups, the proportion of elderly people is much lower than that of young adults, so the chart narrows towards the top and is mostly triangular, like the cross-sections of the pyramid, so the name. The death rate is a count of the number of deaths per unit of time in a given population, which is scaled to the size of that population. The mortality process is commonly expressed in unit deaths per 1,000 people per year. A crucial specific measure of mortality rate is the crude death rate, which makes it look at all-cause mortality in a given time period for a given population. Death causes differ tremendously between developed countries and developing countries.
So, the correct answer is option (D).

Note: The species in a population may be dispersed in a uniform, random or scattered pattern. Uniform means that the population is distributed evenly, randomly spaced, and clumped implies that the division of a population into clusters.
