Cell have several mechanisms for regulating their internal environments. Which of these mechanisms involved in maintaining homeostasis requires energy?

• osmosis

• diffusion

• active transport

• passive transport

Answer explanation

Active transport is the mechanism involved in maintaining homeostasis that requires energy, unlike osmosis, diffusion, and passive transport.

Which property is shared by the cells of all living things?

• The cells contain DNA composed of adenine, thymine, guanine, and cytosine.

• The cells are surrounded by a phospholipid bilayer and a cell wall made of cellulose.

• The cells have chromosomes that are located inside a membrane-bound nucleus.

• The cells rely on mitochondria to carry out aerobic cellular respiration.

Answer explanation

The property shared by all living cells is that they contain DNA composed of adenine, thymine, guanine, and cytosine.

What is the primary role of the stomata in plant leaves?

• To transport nutrients

• To release oxygen and take in carbon dioxide

• To capture light energy

• To protect the leaf from insects

Answer explanation

Stomata release oxygen and take in carbon dioxide during photosynthesis, a crucial process for plant survival.

Which result is most likely to occur to the beetle population due to predation over time?

• The number of light-colored beetles in the population will increase.

• There will be more dark-colored beetles than light-colored beetles.

• The number of light-colored beetles will decrease.

• The dark-colored beetles will move to a different type of tree.

Answer explanation

The number of light-colored beetles in the population will increase as they are less likely to be preyed upon due to their color, leading to a higher survival rate.
