Question
Chapter 21, Problem 1SQ
Summary Introduction
Concept introduction: The rise in number of individuals in a population is called population growth. The
Expert Solution & Answer
Answer to Problem 1SQ
Correct answer: A group of interacting individuals of a single species located within a particular area is a population. Hence, option d. is correct answer.
Explanation of Solution
Reasons for the correct statement:
Option d. is given as, “a population”. A population is a group of interbreed organisms of same species that lives in same area. Demographics are the statistics used to describe population. Plot sampling are the methods mainly used for
Reasons for incorrect statements:
Option a. is given as “a biosphere”. Biosphere is a region of earth and its atmosphere in which living organisms exist and capable for supporting life. Individuals of same species in a particular area is population not biosphere. Hence, option a. is incorrect.
Option b. is given as “an ecosystem”. Ecosystem includes all living and non-living organisms. Individuals of same species in a particular area is population not biosphere. Hence, option b. is incorrect.
Option c. is given as “a community”. Community is a small social unit in which the people share common characteristics like belongs same religion, values, or identity. Individuals of same species in a particular area is population not biosphere. Hence, option c. is incorrect.
Hence, options a., b., and c. are incorrect.
Conclusion
A group of interacting individuals of a single species located within a particular area is a population.

In a population of Jackalopes (pictured below), horn length will vary between
0.5 and 2 feet, with the mean length somewhere around 1.05 feet. You pick
Jackalopes that have horn lengths around 1.75 feet to breed as this appears to
be the optimal length for battling other Jackalopes for food. After a round of
breeding, you measure the offsprings' mean horn length is 1.67. What is the
heritability of horns length (h2)? Is Jackalope horn length a heritable trait? (4
pts)?

There are many differences between DNA replication happening during mitosis in a Douglas fir tree
growing in the Oregon Cascade Mountains and DNA replication happening during a PCR reaction in a
forestry research lab at Oregon State University where the laboratory is amplifying a Simple Sequence
Repeat. Complete the following table that compares the two DNA replication events in terms of the
primers, the nucleotides, the polymerase, and the target sequence. Additionally, give a general value
for the number of copies of the template DNA after one S phase in one cell and after the lab has
completed the PCR reaction.
