Answer:

c. reabsorbing hydrogen

Explanation:

In this scenario, the individual's kidneys will do all of the following except for reabsorbing hyrdogen. This is because, in a scenario like this where the body pH levels decline the kidneys begin to secrete hydrogen, they do not reabsorb it. It is this process of acid elimination that ultimately causes the body's pH levels to begin rising and restoring themselves to normal. Therefore the answer to this question is c.

The muscular system is made up of Multiple choice question. all the muscles plus the nerves attached to them. all the muscles, l
umka2103 [35]

Answer:

all the muscles.

Explanation:

The muscular system is composed of all muscles in the body. The main function of the muscles is to produce movement in different parts, voluntary or involuntary, creating equilibrium. Muscles are made of myocytes. There are three types of muscles: smooth muscle,  skeletal muscle, and myocardium.

  • The smooth muscle is formed by fusiform cells, mononucleated, and no transversal striations. There is a protein contraction system, but not as organized as the one of the skeletal muscle.  

Smooth-muscle can be found in organs, vessels, veins, and arteries. It provides sustained contractions, slow and rhythmical, but not voluntary.  

  • Skeletal muscle is the most abundant muscle in vertebrates, constituting the somatic musculature. It proportionates motion to extremities and digits and is responsible for the position and posture of the individual. It is also involved in eye movements, respiration, mastication, deglutition, and phonation. It moves the tongue, the superior esophagus, and the pharynx.  

The skeletal muscle is innervated by axons of the motor neurons coming from the CNS. The contraction of the skeletal muscle is voluntary and fast.  

Cells composing the striated muscle are significantly long and multinucleated. They arrange in bundles, where cells are parallel to each other.  

  • Myocardium tissue is more similar to the striated tissue than to the smooth one. However, there are some differences between them. Cardiac cells are cylindrical and smaller, with ramifications. Cardiac cells only have one nucleus, and occasionally there can be two. Actin and myosin filaments are arranged just as the skeletal ones, and the contraction of cardiac cells is molecularly very similar to the skeletal

fenix001 [56]

Answer:

The phenomenon that explains the trend seen in the data is that the mosquitoes' evolution has led them to develop resistance to the compound.

Explanation:

This is a very common factor that we can see in insects. The effect of DDT on the species will have different levels of impact. One is going to be more vulnerable to the compound that the rest. However, after many times of exposition to the compound, a few survivors will develop resistance to the compound and their offspring is going to inherit that resistance. Making them increase the resistance over time.
