Answer 1

Answer:

Because cells maintain homeostasis despite the amount.

Explanation:

When a change occurs in an animal’s environment, an adjustment must be made so that the internal environment of the body and cells remains stable. The receptor that senses the change in the environment is part of a feedback mechanism. The stimulus—temperature, glucose, or calcium levels—is detected by the receptor. The receptor sends information to a control center, often the brain, which relays appropriate signals to an effector organ that is able to cause an appropriate change, either up or down, depending on the information the sensor was sending.

Answer 2

Single-celled organisms are able to maintain homeostasis even though they lack higher levels of organization such as organs and organ systems because - all cell structures work together to maintain homeostasis.

Unicellular organisms like bacteria have various ways of maintaining homeostasis. There are various cellular structures and particles to maintain homeostasis. For example,

• Bacteria also have sensors, a protein molecule, that sense and respond to toxic levels of heavy metals in the environment and also help regulate beneficial metal ions.
• Unicellular such as bacteria can control the lipid composition in their plasma membranes to regulate the permeability for substances to move in or out.
• Bacteria and paramecium are unicellular organisms that use contractile vacuoles to control the amount of water inside of them.

Thus, Single-celled organisms are able to maintain homeostasis even though they lack higher levels of organization such as organs and organ systems because - all cell structures work together to maintain homeostasis.
