Active transport moves molecules across the plasma membrane of a cell with the help of transport proteins and energy (ATP).
Active transport is the means of transport of molecules across the plasma membrane with the help of energy. This method is usually used for the transport of molecule against their concentration gradient, i.e., from lower concentration to higher concentration.
Plasma membrane is the outer layer surrounding the cell. It is made up of lipid bilayer, proteins, carbohydrates and cholesterol. The lipid bilayer is amphipathic since the lipid head is hydrophilic and its tail is hydrophobic. The plasma membrane is semi-permeable in nature.

A biotic factor is a living thing that has an impact on another population of living things or on the environment. Abiotic factors do the same thing, but they are non-living. Together, biotic and abiotic factors make up an ecosystem. To survive, biotic factors need abiotic factors.
Yes, Both Cells are Living
According to Cell Theory,
Any thing is Called A "Living Organism" When it Contain 1 pr More Cells
Both Cells Are Able to Produce Their own Energy
Hence, Both are Said Living
Answer:
Burning fossil fuels, and decomposition of dead organisms
Explanation:
The answer is A. The heart pumps blood through the circulatory system, and the lungs help the oxygen transport throughout the respiratory system. :)
