k0ka [10]

Answer:

\huge\boxed{\sf Cerebellum }

Explanation:

Cerebellum is a leaf-like structure that is a part of the hind brain and is responsible for:

  • coordinating skeletal muscle movements.
  • controls movements, posture and balance.
  • involved in learning too.

So, if the cerebellum of the brain is affected/injured, a person can have difficulty in keeping their body in a balanced position, coordinate voluntary movements of skeletal muscles and learning.

Why are producers important to energy transfer within an ecosystem?
slamgirl [31]
<span>Answer: There are only two real sources of energy on the earth. One comes from geothermal from the creation of the earth and the other comes from the sun. You can say wind and nuclear or water, but water's movement is related to the tectonic activity and shaping of the earth and its spin, wind comes from unequal heating of the earth by the sun and nuclear energy comes from isotopes that were formed by a star. So producers are able to harness one of those two energy sources, the sun. Trees and plants are so common because they are using free energy, they have discovered a way to get something for nothing essentially. Predators can use the nutrients they make to supply their own energy but in the end everything boils down to the producers ability to make energy from the sun.</span>

Active tissues that are metabolizing quickly only have a PO2 of 20 mm Hg. How much hemoglobin is saturated at this point? Why is
Mariulka [41]

The percentage of hemoglobin that will be saturated when the PO2 is 20 mmHg is 20%.

<h3>Why is it beneficial for the hemoglobin near these tissues to NOT pick up oxygen?</h3>

It is recommended that the tissues do not absorb oxygen at this point because the affinity of hemoglobin for oxygen will be low since the medium will be acid due to the amount of hydrogen ions and carbon dioxide, situation that occurs in tissues where oxygen is metabolized quickly. Therefore, then there will be no absorption of oxygen from these tissues, but rather it will occur in oxygenated tissues such as the lungs. This is an effect called the 'Bohr effect' and allows oxygen to be released where it is most needed.

And the percentage of oxygen saturation will be 20% according to the hemoglobin saturation curve.
