Keystone Biology Module 2 Part 1

Front

What is selective breeding?

Back

Selective breeding is the process of choosing specific plants or animals to reproduce based on desired traits, leading to offspring that exhibit those traits.

Front

How does selective breeding affect genetic variation?

Back

Selective breeding can reduce genetic variation within a population as it focuses on specific traits, potentially leading to inbreeding.

Front

What is a population in biological terms?

Back

A population is a group of individuals of the same species that live in a specific area and can interbreed.

Front

What is allele frequency?

Back

Allele frequency is the proportion of a specific allele among all allele copies in a population.

Front

What is genetic information?

Back

Genetic information refers to the information encoded in the DNA that determines the traits of an organism.

Front

What is DNA replication?

Back

DNA replication is the process by which a cell makes an exact copy of its DNA before cell division.

Front

What are decomposers?

Back

Decomposers are organisms that break down dead or decaying organic material, returning nutrients to the ecosystem.

Front

What is the role of bases in DNA?

Back

The sequence of bases in DNA encodes genetic information and is crucial for the synthesis of proteins.

Front

What is a food chain?

Back

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.

Front

What is the difference between primary and secondary consumers?

Back

Primary consumers are herbivores that eat producers (plants), while secondary consumers are carnivores that eat primary consumers.
