Life Functions Review

The life function of transport in an organism directly involves those activities used to

• absorb and distribute materials materials

• obtain and hydrolyze materials

• release energy from food

• produce cellular waste products

Nutrition involves those activities by which organisms

• remove cellular waste products

• obtain and process materials needed for other activities

• exchange gases with their environment

• absorb and circulate materials

Which process is a form of autotrophic nutrition?

• transport

• regulation

• photosynthesis

• fermentation

Which statement best describes cellular respiration?

• It occurs in animal cells but not in plant cells.

• It converts energy in food into a more usable form.

• It uses carbon dioxide and produces oxygen.

• It stores energy in food molecules.

In which process are simple materials chemically combined to form more complex materials?

• synthesis

• pinocytosis

• hydrolysis

• cyclosis

A small lizard spends the morning hours lying in the sunlight until its body temperature rises. Later on in the day, the lizard rests in a shady area until its body temperature cools. This type of behavior is important to

• maintain homeostasis

• detect variations

• attract mates

• obtain nutrients

When the human body is responding to stress, the hormone adrenaline is released. A short time later, the body returns to normal. This is an example of how a human

• reacts to an antibody

• develops genetic variation in body cells

• maintains cellular organization

• maintains homeostasis

As a result of their metabolic activities, many organisms produce harmful substances. These substances are eliminated by the process of

• ingestion

• secretion

• pinocytosis

• excretion

The life function responsible for the coordination and control of all life activities in an organism is known as

• regulation

• reproduction

• excretion

• nutrition

Which life function is not necessary for an individual organism to stay alive?

• nutrition

• reproduction

• regulation

• excretion
