Phototropism in plants is a process where a plant bends towards sunlight or any other light source. Phototropism is a mechanism that is necessary for the survival of the plant. This phenomenon is an example of which characteristic of life?

• A. ability to store hereditary information

• B. use of cellular respiration for energy release

• C. ability to move in response to environmental stimuli

• D. living things are made up of cells

The pictures below show processes that occur in all organisms. Which characteristic of life is depicted in all three pictures below?

• A. growth and development

• B. use of energy

• C. respond to environmental stimuli

• D. maintain homeostasis

The projections on the surface of this virus allow the virus to _.

• A. move inside a host cell

• B. attach to a host cell

• C. control a host cell’s DNA

• D. signal other viruses to infect a host cell

Phytoplankton are producers that can live in pond ecosystems. The number of phytoplankton in a pond can be regulated by water temperature, amount of sunlight, water depth, and nutrient load of surface water. Carbon dioxide production in pond water is being studied by researchers because carbon dioxide and water combine to form weakly acidic carbonic acid.

• A. Photosynthesis will decrease, which will result in an increased amount of carbon dioxide in the pond and a decrease in pond acidity.

• B. Photosynthesis will decrease, which will result in a release of carbon dioxide by the phytoplankton and an increase in pond acidity.

• C. Photosynthesis will increase, which will cause the phytoplankton to absorb more carbon dioxide, resulting in a decrease in pond acidity.

• D. Photosynthesis will increase, which will cause the phytoplankton to absorb more carbon dioxide, resulting in an increase in pond acidity.

• C. genetic transmission

• D. structure component

Amylase is a digestive enzyme. Salivary glands in your mouth make salivary amylase, which begins the digestive process by breaking down food into smaller molecules as you chew. Which of these diagrams best represents part of the structure of amylase?

• A. [Diagram showing three 'SUGA' blocks in a row]

• B. [Diagram showing six 'nucleotide' blocks connected in pairs]

• C. [Diagram showing two 'Amino acid' blocks connected]

• D. [Diagram showing 'GLYCEROL' with three 'FATTY ACID' blocks attached]
