Most commonly, individuals of a population show a _______ distribution within their habitat.
- a. clumped
- b. random
- c. nearly uniform
- d. none of the above
Concept introduction: A population is a group of interbreed organisms of same species that lives in same area. Population distribution is an arrangement of population in a particular area according to its conditions and requirements of the society. It also describes the location of individuals relative to one another. There are three types of population distribution, namely clumped, nearly uniform, and random.
Answer to Problem 1SQ
Correct answer: Most commonly, individuals of a population show a clumped distribution within their habitat. Hence, the correct answer is option a.
Explanation of Solution
Reason for the correct statement:
Distribution is a whole number of people or inhabitants in a specified region. Clumped distribution is an uneven distribution of population in the environment. Social interactions between the individuals can also cause the distribution to be clumped.
Option c. is given as “clumped”. In this distribution, the distance between the individuals is minimized. Therefore, the organisms do not move and the offspring are close to their parents. Hence, it shows the clumped dispersion. This limited dispersal ability increases the likelihood of a clumped distribution. Hence, option c. is the correct answer.
Reasons for the incorrect statements:
Option b. is given as “random”. Populations are randomly distributed only if the resources are uniformly available. Random distribution occurs from the nature of relationships between the individuals. Hence, option b. is incorrect.
Option c. given as “nearly uniform”. Nearly uniform distribution occurs only if there is a competition for limited resources with the individuals. Hence, option c. is incorrect.
Option d. given as “none of the above”. Most of the individuals show the clumped distribution within their habitat. Hence, option d. is incorrect.
Hence, options b., c., and d. are incorrect.
Clumped distribution of population occurs within the same habitat. The uneven distribution of resources causes the population to clump together.

- One of the ways for a cell to generate ATP is through the oxidative phosphorylation. In oxidative phosphorylation 3 ATP are produced from every one NADH molecule. In respiration, every glucose molecule produces 10 NADH molecules. If a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?arrow_forwardIf a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?arrow_forwardHow do i know which way the arrows go?arrow_forward

Please note that the focus of this assignment are the (biological) scientific issues associated with rewilding. As will be discussed in class, there are a number of non-scientific issues involved or implicated in rewilding, all ultimately affecting the public acceptability of rewilding. Although these issues are important – indeed, critical – in this assignment you should focus on the biological science issues and questions. Details: You must enumerate at least two pros and at least two cons. Your answer should be no more than 500 well-chosen words, excluding references. Think carefully about how best to organize and structure your answer. Aim for high information density: say a lot, but say it succinctly.
