The correct answer that would best complete the given statement above would be this: A potential benefit of recruiting slow oxidative fivers for contraction before recruiting fast oxidative and fast glycolytic fibers might be because they are slower to respond, slow oxidative fibers must be stimulated first in order contract simultaneously with the faster fibers. Hope this answer helps.
Light energy from the sun and water is needed by the plant to facilitate the light dependent reactions.
The correct option are as follows:
cholera is a bacterial infection of the small intestine.
vaccination provides protection against cholera.
the cholera vaccine is made up of a weakened form of the bacteria that causes cholera.
the vaccine will stimulate production and elicit an immune response.
- If the infection occurs again, the body will produce an even greater attack on the bacteria because of acquired immunity.
- By injecting a heat-killed, weakened organism or its component (antigen) into the body, vaccination aids in the development of immunity. Memory cells and antibodies are produced as a result.
- Memory cells aid in the development of immunological memory, which helps the immune system to respond to microorganisms that the body has previously encountered with greater strength and efficiency during a secondary immune response.
- Memory B cells and memory T cells aid in the development of immunological memory.

Answer:
Increased heart rate, during strenuous exercise, helps to regulate the oxygen reaching the tissues.
Explanation:
Physical exercise implies an increased effort of the muscles, increasing the energetic demand and the substrate to produce more energy.
Both glucose and oxygen are needed by the muscle tissue during physical exercise, so the increased heart rate ensures the supply of oxygen to that tissue.
Therefore, an increase in heart rate contributes to the regulation of oxygen, whose requirements by the muscles increase with exercise.
Other options are not correct because:
<em> A and C. </em><em><u>Water</u></em><em> and </em><em><u>ammonia</u></em><em> regulation is done at the renal level.
</em>
<em> D. Regulation of </em><em><u>temperature</u></em><em> depends on the thermoregulatory center of the nervous system.</em>
Answer:
c. tearing paper
d. cutting your hair
f. freezing water
Explanation:
- for C and D, you're physically doing it
- for freezing, the molecules are still water molecules and you can change it back to solid by melting.
