Answer:
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.

A cellular function that is shared between carbohydrates and lipids is energy production.
Carbohydrates like glucose will be oxidized to pyruvic acid in glycolysis which gets transported to mitochondria where it gets converted to acetyl co-a. Acetyl co-a then enters Kreb's cycle in which Nadh and Fadh molecules are formed these molecules are oxidized in the electron transport chain to form ATP which is an energy currency of a cell. Lipids are oxidized through the beta-oxidation pathway to form acetyl co-a which enters the Krebs cycle to form Nadh and Fadh molecules which are oxidized in the electron transport chain to form ATP. This explains how carbohydrates and lipids share the same function which is energy production.

Options for the question have not been provided. They are as follows:
Substances can pass through them
They are made of muscle
They are located throughout the body
They are made of bone
Answer:
Substances can pass through them
Explanation:
- When a wall or membrane is permeable, it means that substances can pass through it from one side to another.
- Alveoli and capillary have permeable walls.
- Alveoli are found in lungs. They need permeable walls for exchange of gases between the body and the environment.
- Capillaries are a type of blood vessels. They need permeable walls for exchange of nutrients and waste material between the blood and the tissue.
Answer:
In biology, evolution is the change in the inherited traits of a population from generation to generation. These traits are the expression of genes that are copied and passed on to offspring during reproduction. ... Genetic drift arises from the role chance plays in whether a given individual will survive and reproduce.
Heredity - This is the passing on of traits from parents to their offspring either through sexual reproduction or asexual reproduction.
