Chemical messengers and the Electrical signals are the two main methods by which cells communicate with each other to coordinate their functions and metabolic activities.
According to biologist, A cell communicates through chemical messengers, by sending the chemical signals to other cells and also receive that signal from another cell. Similarly, Electrical signals or impulses also work in the same way.
Therefore, body contains many types of lipids which works as a chemical messengers also electical signal or impulses can easily travel throught these lipids. Cell uses these chemical messengers and electrical impulses to communicate with other cell. Although, In order to trigger a response, these signals are transmitted across the cell membrane of the cell.

Cholesterol in Cell membrane strengthens and helps to maintain the fluid nature of a cell regardless of temperature
<u>Explanation:</u>
All organisms are made up of one or more cells. Each cell is protected or differentiated by a covering called as the cell membrane. Phospholipids are the basic structure of the cell membrane. Cholesterol prevents the loss of fluid from phospholipids.
Cell membrane has a lipid layer and cholesterol which is placed between the phospholipids to maintain the fluid nature of the cell under different temperature. Cholesterol prevents the cell from solidifying and helps maintain the fluid. Cholesterol actually acts as a buffer between different temperatures.
<h2>Answer:</h2>
Because condensation on the slant effects the bacterial growth in the test tube.
<h3>Explanation:</h3>
- When agar is solidify in the test tube tilted, it takes a shape of slide on one side of the tube which is known as slat.
- Slant is used instead of petri dishes because they provide more surface area for growth.
- Water in the slat can invade the test tube, making agar unstable and the bacterial growth on the slat will be affected by moisture in bottom of slant.
- In petri dishes, it is no big problem of moisture condensation.
Answer:
The cell is eukaryotic because it contains mitochondria.
nucleus
Explanation:
A doctor need to study chemistry: To know and understand the chemicals processes of matter in the body work which is for example insulin, DNA etc. and to study of all processes in a living organism. The three reasons to study chemistry is because chemistry can be useful in clearing up the natural world, preparing people for career opportunities and producing informed citizens. Some outcomes of modern research in chemistry can lead to technologies that aim to benefit the environment, preserve and produce energy, progress human life and multiply our knowledge of the universe. To help the citizen be a more informed citizen is to let them know how things work makes better decisions and use them better
