Front

What is negative feedback in biological systems?

Back

Negative feedback is a process by which the body senses a change and activates responses to counteract that change, helping to maintain homeostasis.

Front

What is reproduction in living organisms?

Back

Reproduction is the biological process by which living organisms produce new individuals of the same species, ensuring the continuation of their genetic material.

Front

What level of organization is the brain classified as?

Back

The brain is classified as an organ, which is a structure made up of different types of tissues working together to perform specific functions.

Front

What is the role of DNA in living organisms?

Back

DNA contains the genetic instructions necessary for the growth, development, functioning, and reproduction of all living organisms.

Front

What is the difference between positive and negative feedback?

Back

Positive feedback amplifies a response or process, while negative feedback reduces or counteracts a change to maintain stability.
