Fertilization
400
What is negative feedback? Provide an example of negative feedback.
A method your body uses to reverse the change a stimulus causes ( ex. eating--> increase blood glucose--> insulin --> blood glucose goes back to normal) or ( exercise--> increase body temp.--> sweating--> body temp back to normal)

males: testes females: ovary
500
What are Homologous structures
similar structures that related species inherited from a common ancestor.

What is the difference between active transport & diffusion
Active transport uses energy to move molecules against a concentration gradient( low--> high) whereas diffusion moves small molecules with out energy from high to low
