Biology Regents Review: Structure & Function

Front

What are gametes?

Back

Gametes are cells involved in sexual reproduction, specifically sperm and egg cells.

Front

What is homeostasis?

Back

Homeostasis is the process by which organs work together to maintain a stable internal environment, such as balancing oxygen and carbon dioxide levels.

Front

What does cell differentiation mean?

Back

Cell differentiation is the process by which a less specialized cell becomes a more specialized cell.

Front

What controls everything in your body?

Back

DNA controls all functions and processes in the body.

Front

What is a Positive Feedback Response?

Back

A Positive Feedback Response is a process where the output of a system enhances or amplifies the initial stimulus, such as the release of hormones to signal more platelets during bleeding.

Front

What are somatic cells?

Back

Somatic cells are any cells in the body that are not gametes; they make up most of the body's tissues and organs.

Front

What is the role of epithelial cells?

Back

Epithelial cells form protective layers on surfaces and are involved in absorption, secretion, and sensation.

Front

What is the difference between positive and negative feedback?

Back

Positive feedback amplifies a response, while negative feedback reduces or counteracts a response to maintain balance.

Front

What is the function of DNA?

Back

DNA stores genetic information and provides instructions for the development, functioning, growth, and reproduction of all living organisms.

Front

What is the significance of cell specialization?

Back

Cell specialization allows cells to perform specific functions efficiently, contributing to the overall functioning of tissues and organs.
