A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. Animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. Animal cells have a cell membrane, but NO CELL WALL.
Answer:
Nitrogen ---- formed due to the transformation of ammonia (NH3)
carbon dioxide and water vapor ----- released into the atmosphere during volcanic eruptions
helium ------ mostly escaped Earth's atmosphere due to it is light mass.
Explanation:
Nitrogen are formed due to the transformation of ammonia (NH3) due to action of beneficial nitrogen, carbon dioxide and water vapor are released into the atmosphere during volcanic eruptions and helium mostly escaped Earth's atmosphere due to it is light mass. Helium has atomic mass i.e. 2 which is second lowest after hydrogen mass so due to its lighter weight it can't be stay in the atmosphere near to earth.
Mainly to control the movement of substances in and out of the cell. It’s selective so it only allows certain molecules inside such as small molecules like water.
Answer:
stimulus, control center
Explanation:
The control center is the main nervous system of the brain that is used to carry out different sensory, the motor and integration of data.
The stimulus control is the behavioral control that is described as the situations where behavior is triggered by the presence or the absence of any stimulus. Stimulus is the functional reaction in a tissue or any organ.
In the context, the nerve cells in the stomach responds to the stimulus that results from the foods after eating food is a mechanism between the stimulus and the control center.
