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.
By gathering information from past facts
The one with higher air pressure is Warm Air. The reason why is because when you boil water, the water always makes the lid rise. This is because Warm Air has more activity in its atoms and molecules, so it is moving around more, which in turn means that there is more pressure.
Hope I helped. :)
During when we are alive, oxygen is used to make atp, and atp is used to break cross-brdiges when we are relaxing / contracting our muscles. when a person is dead then there is no oxygen but the body can still produce atp via anaerobic glycolysis, when the glycogen is depleted then no atp is produce so the the cross bridges can no logner be broken that is why skeletal muscles lock
Answer: Multicellular organisms are organisms that are made up of more than one type of cell and have specialized cells that are grouped together to carry out specialized functions. Similar cells are grouped into tissues, groups of tissues make up organs, and organs with a similar function are grouped into an organ system.
hope it help
