Question 3

Which of the following is NOT an essential characteristic of life?

Accepted Answer

Multicellularity and organ systems.

Question 4

Which level of biological organization is defined as all the living things in a particular area?

Accepted Answer

Ecosystem

Question 5

After eating a meal, the level of glucose in a person's blood rises. The body responds by releasing insulin, which causes cells to take up glucose and lower blood sugar. What type of regulation does this illustrate?

Accepted Answer

Accepted Answer

Eukaryotic cells have a nucleus containing DNA.

Question 7

Which of the following best describes the role of DNA in living systems?

Accepted Answer

DNA contains genetic information that is inherited and directs cell function.

Question 8

Which of the following is the correct sequence for gene expression?

Accepted Answer

DNA → mRNA → Protein

Question 9

Which of the following is an example of evolutionary adaptation?

Accepted Answer

The peppered moth becoming darker in color during the Industrial Revolution.

Question 10

Which of the following best describes the difference between an element and a compound?

Accepted Answer

A compound is made up of two or more different elements combined in a fixed ratio.

Question 11

Which subatomic particle is found outside the nucleus and has a negative charge?

Accepted Answer

Electron

Question 12

How is the atomic number of an atom related to its identity?

Accepted Answer

It is determined by the number of protons in the nucleus.

Question 13

Which of the following is true about isotopes of the same element?
