Unit 1 BIO120 exam

Front

What is the movement of substances throughout the body called?

Back

Circulation is the movement of substances throughout the body, including the transport of nutrients, gases, and waste products.

Front

Which structure in a cell is responsible for packaging and distributing proteins?

Back

The Golgi Body is responsible for modifying, sorting, and packaging proteins for secretion or delivery to other organelles.

Front

What type of cell tissue discharges its secretions into ducts?

Back

Exocrine tissue discharges its secretions into ducts, such as sweat glands and salivary glands.

Front

What occurs during interphase?

Back

During interphase, the cell grows, DNA is replicated, and the cell prepares for division. However, two new cells are not made during this phase.

Front

How many principal types of tissue are there in the human body?

Back

There are four principal types of tissue: epithelial, connective, muscle, and nervous tissue.

Front

What is the primary function of the circulatory system?

Back

The primary function of the circulatory system is to transport blood, nutrients, gases, and waste products throughout the body.

Front

What is the role of the Golgi Body in cellular function?

Back

The Golgi Body modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

Define exocrine glands and provide an example.

Back

Exocrine glands are glands that secrete substances through ducts to the outside of the body or into the digestive system. An example is the pancreas.

Front

What happens to DNA during interphase?

Back

During interphase, DNA is replicated to ensure that each new cell will have an identical set of chromosomes.

Front

List the four principal types of tissue in the human body.

Back

The four principal types of tissue are epithelial, connective, muscle, and nervous tissue.
