<h2>What is a feedback mechanism?</h2>

A feedback mechanism is a physiological regulation system in a living body that works to return the body to its normal internal state, or commonly known as homeostasis. In nature, feedback mechanisms can be found in a variety of environments and animal types. Feedback occurs when outputs of a system are routed back as inputs as part of a chain of cause-and-effect that forms a circuit or loop. The system can then be said to feed back into itself.

Examples:

  • Menstrual cycle. At the beginning of the menstrual cycle, the ovaries release the hormone estrogen. The estrogen acts as a stimulus for the positive feedback loop. ...
  • Childbirth. Figure: Normal childbirth is driven by a positive feedback loop.

In your own words, explain the processes responsible for the formation of a reverse fault.
zzz [600]
Reverse faults are exactly the opposite of normal faults. If the hanging wall rises relative to the footwall you have a reverse fault. Reverse faults occur in areas undergoing compression. If you imagine undoing the motion of a reverse fault, you will undo the compression and thus lengthen the horizontal distance between two points on either side of the fault.
if you stood on the fault plane the block on the right would be under your feet. this is thus the footwall. The tan sandstone has been pushed up and over itself. This offset of the hanging wall indicates that this is a reverse fault.

Doctors do not administer vaccinations to people who are too sick. Which best explains why?
4vir4ik [10]

Answer:

D, The white blood cells of sick people may not be able to efficiently handle the weakened or dead form of the pathogen.

Explanation:

Vaccinations are essentially just weak diseases we use to create antibodies so the body can protect itself from the full disease. If it sees it once, it can defend itself, is the theory. This is choice D.

  • Why not A: The weakened form will be attacked by the immune system, but maybe not enough, because the person is so sick that the immune system is busy elsewhere.
  • Why not B: The medication is not what combines with the vaccine to cause problems. It is the body being overworked.
  • Why not C: The digestive system isn't the issue. You don't eat diseases.

Theodor W. Engelmann illuminated a filament of algae with light that passed through a prism, thus exposing different segments of
larisa86 [58]

Answer:

The correct answer will be option-D

Explanation:

The aerotaxis movement experiment performed by the Theodor W. Engelmann played an important role in understanding the photosynthesis.

The experiment was performed on the <em>Spirogyra </em>filamentous algae which were exposed to a different wavelength of light.

The other aerobic bacteria present in the test tubes started moving and accumulated near the two regions of the <em>Spirogyra</em> where they were exposed to the blue and red light of the VIBGYOR.

The region receiving red and blue light produced more oxygen through photosynthesis which indicated that these two wavelengths of the light are more active for photosynthesis than any other wavelengths.

Thus, option-D is the correct answer.
