Front

What is a retrovirus?

Back

A retrovirus is a type of virus that uses RNA as its genetic material and can integrate its genetic material into the host's DNA.

Front

What does it mean for a virus to be nonliving?

Back

Viruses are considered nonliving because they do not grow, develop, or carry out metabolic processes on their own.

Front

What are the three domains of life?

Back

The three domains of life are Bacteria, Archaea, and Eukarya.

Front

What distinguishes Bacteria from Archaea?

Back

The DNA sequences of Archaea genes are more similar to eukaryotes than to bacteria.

Front

What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

How do mutations contribute to evolution in prokaryotes?

Back

Mutations that occur during binary fission can lead to genetic variation, which is essential for evolution.

Front

What is antibiotic resistance?

Back

Antibiotic resistance occurs when bacteria evolve and develop the ability to survive exposure to antibiotics that once killed them.

Front

What is the role of genetic material in viruses?

Back

Genetic material in viruses contains the information necessary for the virus to replicate and infect host cells.

Front

What is homeostasis?

Back

Homeostasis is the ability of an organism to maintain a stable internal environment despite changes in external conditions.

Front

What is the significance of viral replication?

Back

Viral replication is significant because it allows viruses to multiply and spread, potentially causing disease.
