Answer:
The correct answer is: adaptive immunity.
Explanation:
Adaptive immunity (also called acquired immunity) is one of the two parts of the immune system.
Unlike the innate immunity that responds to any pathogens, the adaptive immunity is highly specific and provides long-lasting protection because once the cells from adaptive immunity contact the antigen (any molecule that triggers an immune response) they become ready to fight them again later in life with a much more efficient approach - this is what is known as immunological memory and is the reason vaccines work.
Acquired immunity does not need a stimulus to exist, unlike innate immunity (the later only acts when there are pathogens involved).
The acquired immune system is mostly integrated by lymphocytes.
Answer:
This structure which allows these passages is called the cell membrane. Substances outside the cell can move in and out of the membrane through a process called diffusion. When the substance in question is water, the process is referred to as osmosis. ... Water can be put back into a raisin through the process of osmosis.

Answer:
In biological system, cell is known as the basic unit of all organisms. Unicellular organism consist of one cell only but that single cell helps them to perform all the functional activity.
Levels of organization in biological systems is defined as the hierarchy of several components from smallest to complex in biological system.
Cell is one of the important part of Levels of organization in biological systems, as in multicellular organisms group of cells form tissue that create an organ and many organs together form organ system within an organism. The cell is basic unit in all organisms and without a cell, an organism can not develop.
The group of these organism formed from a small cell then form complex component of Levels of organization such as population, community, ecosystem and Biosphere (in sequential order).
Answer:
To find force is M x A the mass has to be in kg so 2000g = 2 kg and A= 8.3 m/s2 so 2 x 8.3 = 16.6 then the force is 16.6 newtons.
