There are two types of feedback mechanisms
Positive feedback heightens the intensity
Negative feedback lowers the intensity
These all serve to maintain homeostasis. Homeostasis is the state where the internal and external part of the body maintains and establishes balance and equilibrium. </span>
In this situation, muscle cells ferment glucose to two molecules of lactic acid — again, with the net production of only two molecules of ATP per glucose molecule (Figure 16-6, left).
Since chloroplast use energy to make food for plant cells (Photosynthesis) I could compare it to lunch money, and how you have to keep refilling up, and up, just to use it again for food, for yourself.
Protist are eukaryotic organisms that cannot be classified as a plant animal fungus. They are mostly unicellular, but some like algae, are multicellular. Kelp, or “seaweed” is a large multicellular protist that provides food, shelter, and oxygen for numerous underwater ecosystems.
