3. An Apple Turning Brown
Explanation:
When an apple is cut (or bruised), oxygen is introduced into the injured plant tissue. When oxygen is present in cells, polyphenol oxidase (PPO) enzymes in the chloroplasts rapidly oxidize phenolic compounds naturally present in the apple tissues to o-quinones, colorless precursors to brown-colored secondary products.

Glands are organs that <u>regulate bodily functions by producing and releasing certain substances</u>. Endocrine glands are a type of gland that specifically releases its product into the bloodstream.

An example of an endocrine gland is the pancreas. The pancreas produces insulin and glucagon, two different hormones that act in different organs to regulate glucose levels.
Reproduction, growth, renewal and repair are all reasons for cell division in multicellular organisms.
Cell division is a process that allows a parent cell divides into more smaller cells. It is classified as mitosis and meiosis. Mitosis produces diploid cells that will be used for growth or repairing tissue. Meiosis will produce gamete that has a role in reproduction.
