How do the functions of the skeletal and muscular system differ? A. Muscles provide structure and support to the body, while bon

Yuki888 [10]

Answer:

B. Bones provide structure and support to the body, while muscles move the bones.

Explanation:

Let's try to eliminate choices.

A: "Muscles provide structure and support to the body, while bones move the muscles."

Muscles actually aren't the ones that provide support for our body; it's the bones and our skeletons that do that. So, this is wrong.

B: "Bones provide structure and support to the body, while muscles move the bones."

Bones do, in fact, provide structure to our bodies, and muscles are the ones that attach to the bones through tendons and help move them. So, B is correct.

C: "Bones send signals to the body, and muscles are responsible for movement."

While it's true that muscles are responsible for movement, bones do not send signals to the body; that's the nervous system's job. C is wrong.

D: "Muscles send signals to the body, and bones are responsible for movement."

Again, muscles don't send signals; neurons do. D is wrong.

The answer is B.

Glucose is broken down in the chemical processes of aerobic respiration.

Papessa [141]

$\bold{\huge{\purple{\underline{ Answer }}}}$

Aerobic respiration :- Aerobic respiration is process of respiration in which complete oxidation of glucose takes place in the presence of oxygen

That is, 

Aerobic respiration is takes place in four stages :-

Glycolysis
The link reaction
The Krebs cycle
Oxidative phosphorylation

In aerobic respiration, Glucose with 6 carbon atoms broken into 2 pyruvic acid each with 3 carbon atom and produces water + CO2 + energy.

<h3>Whereas, </h3>

Anaerobic respiration :- is the process of respiration in which incomplete oxidation of glucose takes place in the absence of oxygen

The end products of glucose in anaerobic respiration is

In human muscles,  Lactic acid + Energy
In yeast, Ethanol + CO2 + Energy

Hence, Option D is the correct answer.
