Answer: A. Chemical signal
Explanation:
Chemical signal is the type of communication which coordinates actions between neighboring cells
.
This ability originated in single cells organisms and was essential for the evolution of multicellular organisms because after a cell receives a message, it is transferred across the plasma membrane and changes are brought about within the cell in response to this message.

Answer:
They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body's hereditary material and can make copies of themselves. Cells have many parts, each with a different function.
Explanation:
Answer:
- The wind is caused by differences in air pressure.
- An anemometer is a tool for measuring wind speed.
- The wind-chill factor has a cooling effect
Explanation:
Winds move from areas of high pressure to areas of low pressure. This is because the areas of low pressure are composed of hotter and less dense air. The cooler air from the higher pressure region rushes in to displaces the rising warm less dense air. The direction from which the winds prevail FROM is used to name the winds(such as westerlies blow from West to East). A wind vane, windsock and anemometer measure the direction and speed of wind. As wind passes over the skin, it causes a cooling effect (the wind chill factor) because it blows the sweat away from the skin carrying with it the heat.
