3:1

Question 11

Which of the following is an ethical concern associated with the release of bioengineered organisms into the environment?

Accepted Answer

Potential disruption of natural ecosystems and loss of biodiversity.

Question 12

Which of the following best explains how natural selection can lead to evolution in a population over time?

Accepted Answer

Individuals with advantageous traits are more likely to survive and reproduce, passing those traits to the next generation.

Accepted Answer

Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species

Question 14

Which of the following statements best distinguishes viruses from bacteria?

Accepted Answer

Viruses are not considered living organisms because they cannot reproduce independently, while bacteria are living cells that can reproduce on their own.

Accepted Answer

Archaea

Question 17

Which of the following best describes the process of DNA replication?

Accepted Answer

The double helix unwinds and each strand serves as a template for the synthesis of a new complementary strand.

Question 18

Which of the following best defines the term 'genotype'?

Accepted Answer

The genetic makeup of an organism, represented by its alleles.

Question 19

Which of the following is a real-world example of how understanding cell division is important in medicine?

Accepted Answer

Cancer treatment targets rapidly dividing cells to prevent tumor growth.

Question 20

Which of the following best explains why water is considered a polar molecule?

Accepted Answer

It has an uneven distribution of electrons, resulting in a partial positive charge on hydrogen and a partial negative charge on oxygen.
