Biology SOL Review (Part 1)

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts to speed up chemical reactions without being consumed in the process. They lower the activation energy required for reactions to occur.

Front

How do mammals primarily regulate body temperature during exercise or heat exposure?

Back

Mammals primarily regulate body temperature through sweating.

Front

What is the relationship between cellular structures and the entire organism?

Back

Cellular structures are specialized components that perform specific functions within the organism.

Front

Who discovered the double-helix structure of DNA?

Back

James Watson and Francis Crick are credited with discovering the double-helix structure of DNA.

Front

What primarily constitutes the cell membrane?

Back

The cell membrane is primarily made up of phospholipids, proteins, and carbohydrates.

Front

What is a catalyst?

Back

A catalyst is a substance that increases the rate of a chemical reaction without undergoing any permanent chemical change.

Front

Define homeostasis in biological systems.

Back

Homeostasis is the process by which biological systems maintain a stable internal environment despite external changes.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis in the cell.

Front

What is the significance of the cell membrane's phospholipid bilayer?

Back

The phospholipid bilayer provides a flexible barrier that separates the interior of the cell from the external environment, allowing selective permeability.

Front

What is the primary function of DNA?

Back

The primary function of DNA is to store and transmit genetic information.
