Chapter 53: Q6TYU (page 1188)

The observation that members of a population are uniformly distributed suggests that

(A) resources are distributed unevenly.

(B) the members of the population are competing for access to a resource.

(C) the members of the population are neither attracted to nor repelled by one another.

(D) the density of the population is low.

Short Answer

Expert verified
  1. The statement 鈥渞esources are distributed unevenly鈥� is false.
  2. The statement 鈥渢he members of the population are competing for access to a resource鈥� is true.
  3. The statement 鈥渢he members of the population are neither attracted to nor repelled by one another鈥� is false.
  4. The statement 鈥渢he density of the population is low鈥� is false.

Step by step solution

01

Population

In demographics, when the total number of organisms of a single species occupies a place to live there is called population.

02

Explanation of option ‘(A)’

The physical material that adds value to the life of living organisms like human beings and is obtained from the ecosystem is called resource.

Thus, the uneven resource distribution is considered as a clumped distribution.

Therefore, the given statement is false.

03

Explanation of option ‘(B)’

The different resources that living organisms compete for are food, space to live, and water.

Thus, the organisms鈥� distribution within a habitat is based on access to resources.

Therefore, the given statement is true.

04

Explanation of option ‘(C)’

Some of the important factors that determine the size of a population are natural changes like birth rate (natality), death rate (fatality rate), immigration, and outmigration.

Thus, the species within a population interact with each other.

Therefore, the given statement is false.

05

Explanation of option ‘(D)’

The demographers study population density as a measure determining the population distribution in a place by estimating the number of people occupying a geographical area.

Thus, the thinly-dispersed individuals are having a low-population density.

Therefore, the given statement is false.

Most popular questions from this chapter

(a) Find the vertical and horizontal asymptotes.

(b) Find the intervals of increase or decrease.

(c) Find the local maximum and minimum values.

(d) Find the intervals of concavity and the inflection points.

(e) Use the information from parts (a)鈥�(d) to sketch the graph of f.

60. \(f\left( x \right) = \frac{{{x^2} - 4}}{{{x^2} + 4}}\)

The graph of the derivative \(f'\) of a continuous function \(f\) is shown

  1. On what intervals is f increasing? Decreasing?
  2. At what values of \(x\) does f have a local maximum? Local minimum?
  3. On what intervals is f concave upward? Concave downward?
  4. State the \(x\)-coordinate(s) of the point(s) of inflection.
  5. Assuming that \(f\left( 0 \right) = 0\), sketch the graph of f.

  1. Find the intervals of increase or decrease.
  2. Find the local maximum and minimum values.
  3. Find the intervals of concavity and the inflection points.
  4. Use the information from parts (a)-(c) to sketch the graph. You may want to check your work with a graphing calculator or computer.

54. \(G\left( x \right) = 5{x^{\frac{2}{3}}} - 2{x^{\frac{5}{3}}}\)

In 2014, the United States had a population of 320 million people. If the (annual) per capita change in population size (r鈭唗) was 0.005, how many people were added to the population that year (ignoring immigration and emigration)? What would you need to know to determine whether the United States is currently experiencing exponential growth?
