Answer:
A feedback loop is a biological occurrence where the output of a system amplifies the system (positive feedback) or inhibits the system (negative feedback).
Explanation:
Example, during blood clotting, a cascade of enzymic proteins acitvates each other, leading to the formation of fibrin clot that prevents further blood loss.

Answer:
permeability
Explanation:
dictionary definition: the state/quality of a material or membrane that causes it to allow liquids or gases to pass through it
in biology we use this term to describe the cell membrane, it is "semi-permeable" because it allows certain gasses and molecules to pass through
Answer:
1. mitochondria
2. centrioles
3. lysosome
4. cytoplasm (cytosol)
5. nucleolus
6. nuclear envelope
7. chromosomes
8. cilia
9. Rough endoplasmic reticulum
10. Golgi apparatus
11. citoesqueleton
12. vesicles
13. ribosomes
14. smooth endoplasmic reticulum
15. cell membrane
Explanation:
Mitochondria are the energy centers of the cell that work to produce ATP. Centrioles are organelles composed of tubulin protein that organize microtubules that serve as the cell's skeletal system. Lysosomes are vesicles that contain hydrolytic enzymes. The cytosol is a thick solution inside the cell which is enclosed by the cell membrane. The nucleolus is an organelle inside the cell nucleus involved in the transcription of ribosomal RNAs. The nuclear envelope is a membrane that surrounds the cell nucleus (in eukaryotic organisms). Chromosomes are linear molecules composed of chromatin (DNA + histone proteins) which contain the genetic material of the cells. The cilia are organelles found on eukaryotic cells involved in the movement of the cell. The rough endoplasmic reticulum is an organelle whose function is the processing of proteins synthesized in the ribosomes, while the smooth endoplasmic reticulum functions in lipid synthesis. The Golgi apparatus is an organelle involved in transporting and packaging proteins and lipids. The cytoskeleton is a dynamic network of protein filaments that act as the skeleton of the cells. Vesicles are membrane-bound structures that transport substances in the cell. The cell membrane is a lipid bilayer that acts to transport nutrients into the cell and waste products out of the cell.
