What is Anhidrosis?

Back

Anhidrosis is the inability to sweat normally, which can prevent the body from cooling itself and maintaining homeostasis.

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms regulate their internal environment to maintain stable, constant conditions.

Front

What is a feedback mechanism?

Back

A feedback mechanism is a biological process that helps maintain homeostasis by responding to changes in the internal or external environment.

Front

What structure is present in plant cells but not in animal cells?

Back

Chloroplasts are present in plant cells but not in animal cells.

Front

What is the role of lysosomes in a cell?

Back

Lysosomes are organelles that contain enzymes to digest food and break down waste materials in a cell.

Front

What is the effect of toxic chemicals from smoking on the body?

Back

Toxic chemicals from smoking can stimulate uncontrolled cell division, leading to cancer.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in an organism's traits.

Front

How can mutations be passed from parent to offspring?

Back

Mutations can be passed from parent to offspring if they occur in gametes (sperm or egg cells).

Front

What is the difference between gametes and body cells?

Back

Gametes are reproductive cells (sperm and eggs) that carry genetic information, while body cells are somatic cells that make up the tissues and organs of an organism.

Front

What is the significance of organelles in single-celled organisms?

Back

Organelles in single-celled organisms perform functions similar to organs in multicellular organisms, allowing them to carry out necessary life processes.
