The plasma membrane is the boundary between the cell and its environment. It regulates what enters and exits the cell. Cells must maintain an appropriate amount of molecules to function inside them. They must also have a way to keep things out or to allow things to enter. This is the job of the plasma membrane. The plasma membrane is like the guard at a gated community. The guard must inspect those who enter and those who leave to make sure that only the people and things needed in the community are there.
The cell membrane is a thin semi-permeable membrane that surrounds the cytoplasm of a cell. Its function is to protect the integrity of the interior of the cell by allowing certain substances into the cell, while keeping other substances out. It also serves as a base of attachment for the cytoskeleton in some organisms and the cell wall in others. Thus the cell membrane also serves to help support the cell and help maintain its shape.
The most prominent roles of mitochondria<span> are to produce the energy currency of the cell, ATP (i.e., phosphorylation of ADP), through respiration, and to regulate cellular metabolism. The central set of reactions involved in ATP production are collectively known as the citric acid cycle, or the Krebs cycle</span>
Answer:
G 0 is a resting phase where the cell has left the cycle and has stopped dividing. The cell cycle starts with this phase.
Answer:
Removing just one species can be a disturbance
Explanation:
Ecosystem consists of a diverse organism and there is a complex interactions between those organisms.For instance if plant species keeps on growing and the animals which exists by consuming these plants suppose if such animal population grows then there will be reduction in the plant population Ecosystem contains many such dependencies.Therefore removing just one species can cause a disturbance to the biodiversity of an ecosystem.
