Answer:
okay buddy, have fun with that.
Explanation:
thanks
Cancerous cells often produce tumor markers as well as its own cancer cells that act as antigens that can be recognized by antigen presenting cells and be presented to natural killer (NK) cell progenitors that are found in the spleen, lymph nodes, thymus, and other lymphoid organs. With malignancy, the production of NK cells will be increased. NK cells works by killing cells that do not have an inhibitory signal (i.e. cancer cells) and preserving cells that do have an inhibitory signal (i.e. normal body cells).
When the water enters the cells, they swell and become bowed. This causes the guard cells to bend away from each other, thereby opening thestomata. Conversely, when guard cellslose potassium ions, water diffuses out of the cells by osmosis.
Producers are organisms (usually plants) that utilize photosynthesis to produce their own food supply.
Photosynthesis is a process that uses photons from the sunlight to turn glucose and oxygen into carbon dioxide and energy. It basically is a process that uses light energy to make a usable food source, and it takes place in the cells of a chloroplast.
Chlorophyll is a green pigment found inside of plants' chloroplasts that absorbs light photons, allowing photosynthesis to take place.
Answer:
The answer is "ligand-gated channel".
Explanation:
The action that is described in the question is an example of a "ligand-gated channel".
The ligand-gated channels are found in the muscles and they are membranes made out of ion-channel proteins which chan be controlled by certain released chemicals into the medium to open them up or closed them and allowing the sodium, potassium or calcium ions to pass through.
I hope this answer helps.
