Midterm Review 1

One characteristic of all living organisms is that they

• make food

• live on land

• maintain homeostasis

• move from place to place

Which sequence is listed in order from simplest to most complex?

• tissue - cell - organ system - organ

• cell - tissue - organ - organ system

• cell - tissue - organism - organ

• organism - tissue - organ - organ system

A biologist would most likely study all of the chemical activities of an organism to obtain information about the organism's

• number of mutations

• reproductive cycle

• development

• metabolism

Cells are to tissues as organs are to

• organ systems

• cells

• genes

• organelles

The ability of an organism to maintain internal stability is known as

• metabolism

• homeostasis

• circulation

• excretion

Which statement about cells is NOT true?

• one or more cells make up all living organisms

• cells carry on the basic life functions of living organisms

• cells contain structures that carry on life functions

• most cells cannot reproduce

Living things are made mostly of these four main elements:

• hydrogen, oxygen, nitrogen, and protein

• water, protein, carbohydrate, and fat

• carbon, hydrogen, oxygen, and nitrogen

• glucose, salt, mineral, and base

Which structure is the boundary between a living cell and its environment?

• cell membrane

• cytoplasm

• vacuole

• ribosome

The cell nucleus functions

• in obtaining energy for the cell

• in the storage of digestive enzymes

• as the center of control for cell metabolism and reproduction

• in the transport of materials throughout the cell

The genetic material of an animal cell is found in the

• nucleus

• cytoplasm

• ribosomes

• vacuole
