Scince Why do cells need to adjust when conditions change?

A cell is the basic block of life and is always changing to fit its environment.

Explanation:

A cell is the basic founding block of a living organisms. In other words, a cell is the basic membrane  unit which contains fundamental molecules of life. It is the cell that all living things are composed of.

The cell always changes with the surroundings and environment and it adapts to it. The cells requires a constant adjustments as the conditions inside and the outside the cells changes to keep a stable internal environment. Because the environment internally and externally is always changing, the cell continuously make adjustments to stay at or the near the set point.

It models conduction because the painter represents a charged object and the paint represents electrons that are transferred through contact.

Explanation: Charge can be transferred from higher potential to lower potential object via three methods:

1. Friction: When two objects are rubbed with each other. Both get charged up due to difference in the electric potential.

2. Conduction: When charged object comes in direct contact with an uncharged one and transfers charge.

3. Induction: When a charged object is brought near an uncharged object, it induces charge.

Thus, Shareen when shakes her hand with the painter, the paint gets transferred to her hand. Transfer of paint takes place due to contact. Here, painter represents a charged object and paint represents electrons that are transferred.
