Chapter 22: Problem 15

Organisms a. compete with other members of their species b. vary in physical characteristics. c. are adapted to their environment. d. are related by descent from common ancesto e. All of these are correct.

Short Answer

Expert verified
All of the given statements (a, b, c, and d) are correct regarding organisms. They compete with other members of their species, vary in physical characteristics, are adapted to their environment, and are related by descent from a common ancestor. Therefore, the short answer is e. All of these are correct.

Step by step solution

01

Analyze statement a

Competing with other members of their species is a common characteristic of organisms. This competition helps ensure the survival of the fittest individuals within the species. Therefore, statement a is correct.
02

Analyze statement b

Organisms show variations in physical characteristics. These variations help them to adapt to their environment and can also affect their ability to compete for resources and mates. Thus, statement b is accurate.
03

Analyze statement c

Organisms, over time, tend to become adapted to their environment through natural selection. This adaptation helps them to survive, reproduce, and pass on their favorable traits to the next generation. Consequently, statement c is correct.
04

Analyze statement d

Organisms are related by descent from common ancestors. This origin of closely related species from a single ancestor is a fundamental concept in the study of biology and evolution. As a result, statement d is accurate.
05

Analyze statement e

Statement e states that all of the previous statements (a, b, c, and d) are correct. As we have already analyzed and found statements a, b, c, and d to be accurate, statement e is the correct answer to this exercise.
