Answer:

Explanation:

In the spring, grass often dies near the roads that have been salted because, after salt has been applied and it fell on grasses, the salts penetstrate through the plant cell, and dehydrate water from the cells of the plant. Which result in loss of water in the cell and this make the cell not to be able to perform it's functions because of loss of water and hence because water us essential for it and it is lost, grasses dies.

These cellular structures are utilized in strong involuntary muscle contractions and transmission of electrical impulses. ______
sertanlavr [38]

Answer:

The best answer to the question: These cellular structures are utilized in strong involuntary muscle contractions and transmission of electrical impulses, would be: T-Tubules.

Explanation:

In both skeletal and cardiac muscle, not smooth muscle, because of the way that the muscle fibers are conformed into tight bundles of sarcomeres (skeletal muscle) and myocardiocytes (cardiac muscle), there is a need for a series of structures that will ensure that when there is a stimulus from the nervous systems, these stimulus will propagate to all the cells in the fibers, and not just one.

Aside from counting with a neuromuscular motor plate, which will receive the neurotransmitter from the nerve endings and produce the appropriate reactions, as well as propagate that reaction to all the cells that are being stimulated, muscle fibers also have a structure known as T-Tubules. T-Tubules are formations much like roadways of cell plasma membrane that connect not just one, but all the cells within a muscle fiber so that once a stimulus comes, all the cells will initiate the process of calcium release and action potential propagation. These T-Tubules will ensure that electrical impulses reach all muscle cells and that all cells react at the same time as needed.

A researcher is trying to design an experiment to measure the amount of energy a person uses during different activities. He pro
Tomtit [17]

The right answer is to measure the amount of released carbon dioxide.

The carbon dioxide exhaled by the lungs can reflect the energy consumed by the body since it comes from the degradation of glucose which is the main energy substrate. And this is a better indicator of energy consumption than measuring heart rate because it can be inflected by several factors.


A is false because glucose is not found in the urine, except in the case of diabetes mellitus.

C is false because the consumption of calories does not mean that we will directly use it.

D is wrong because perspiration is independent of energy consumption, this is a way to cool the body after exercise.
