The three domains of life are Archaea, Bacteria, and Eukarya.

Front

What is the primary function of DNA in cells?

Back

The primary function of DNA in cells is to serve as instructions for making proteins.

Front

What is active transport in cellular processes?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, using energy (ATP).

Front

What are proteins made of?

Back

Proteins are made of long chains of amino acids.

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

Front

What is the role of hemoglobin in the body?

Back

Hemoglobin is a protein in red blood cells that carries oxygen from the lungs to the rest of the body.

Front

What is the significance of beak shape in finches?

Back

Beak shape in finches is an adaptation that affects their feeding strategies and survival in different environments.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy and moves substances along a concentration gradient, while active transport requires energy to move substances against a concentration gradient.

Front

What are the four main types of macromolecules?

Back

The four main types of macromolecules are carbohydrates, lipids, proteins, and nucleic acids.

Front

What is a selectively permeable membrane?

Back

A selectively permeable membrane is a barrier that allows certain substances to pass while blocking others.
