The answer is F, false. Natural selection is still involved, with stronger and more procreative individuals spreading their genes. An example of when natural selection is not involved would be when human breeders look for specific traits and breed accordingly.
Answer: C. Positive feedback mechanisms are overwhelmed.
Explanation:
Homeostasis, is the maintenance of a normal internal environment, in the face of external and internal disturbances, so that the functions of cells and systems of the body are preserved. This is accomplished primarily through feedback systems, so when a system is disturbed, a diversity of local responses, systemic reflexes (rapid reactions and automatic stimuli) and long-term adjustments are activated to bring the system back to its normal equilibrium point.
Most systems are controlled by negative feedback mechanisms, with the controlled variable being able to "turn off" its release, in the same way as a thermostat controls the temperature of a room. So, in this context, too much positive feedback would be related to harmful effects, such as homeostatic imbalance.
The American public owns all federal public lands, including National Parks, National Forests, Wilderness areas, wild and scenic rivers, and wildlife preserves. Every American has a personal stake and a guaranteed say in how these places are cared for.
I also do Acellus :)
Answer:
in cellular respiration food is oxidized to CO2 while O2 is reduced into H2O Cellular respiration takes in food and uses it to create ATP, a chemical which the cell uses for energy. Usually, this process uses oxygen, and is called aerobic respiration.Aerobic respiration, the process that does use oxygen, produces much more energy and doesn’t produce lactic acid. It also produces carbon dioxide as a waste product, which then enters the circulatory system
The three molecules are Nadh, Fadh and ATP
