In humans, the maintenance of a stable internal temperature is a direct result of

• detection of and reaction to stimuli in the environment

• digestion of starches and absorption of protein from the internal environment

• diffusion of water and excretion of glucose to the external environment

• transport of ATP and locomotion through the environment

Which life process is classified as autotrophic in some organisms and heterotrophic in other organisms?

• hormonal regulation

• transport

• nutrition

• respiration

The process that removes metabolic waste products from an organism is known as

• egestion

• secretion

• excretion

• oxidation

After eating a meal, sugar levels are elevated. The body releases hormones to help absorb excess sugar into cells and return sugar levels to normal. This is an example of

• excretion

• regulation

• reproduction

• transport

By which life function does an organism produce energy?

• respiration

• excretion

• synthesis

• reproduction

The manufacture of proteins in the body is an example of the life function called

• excretion

• respiration

• synthesis

• reproduction

The movement of fluids by various cells of the human body is part of the life function known as

• excretion

• transport

• respiration

• growth
