Which muscles do you control when exercising? cardiac muscles skeletal muscles involuntary muscles smooth muscles?
Mashutka [201]

While doing exercise, one can control skeletal muscles only.

The body has three kinds of muscles, that is, skeletal muscle, cardiac muscle, and smooth muscle. The skeletal muscles are linked with the bones of the skeleton, that is why these are under control and are known as voluntary muscles.

On the other hand, the smooth muscles like skeletal muscle can never be under control. These muscles helps in pushing substances, like blood or food through organs. The cardiac muscle is also an involuntary muscle, which is found only in the heart. These muscles helps in contraction of the heart and can never be controlled.

Ray Of Light [21]
Pork and beef insulins are similar to human insulin, differing only in one or a few amino acids. However, even a slight difference is enough to elicit an allergic response in some people. To overcome this problem, researchers looked for ways to make insulin that would more closely resemble human insulin.

Frogs have lungs for breathing, but they also absorb dissolved oxygen directly through their skin. This allows respiration to oc
alukav5142 [94]

Answer: B. Water breaks down into oxygen molecules for respiration.  


Water is the required for photosynthesis, a process by which plants (terrestrial and aquatic) makes their food by utilizing water as a reactant to produce oxygen and glucose as product. The glucose act as a source of energy for conducting various metabolic processes in plants but oxygen is released in the air.

6CO_2\ \ \ \ +6H_2O\rightarrow\ C_6H_{12}O_6+6O_2\\carbon\ \ \ \ water\ \ \ \ \ \ \ \ glucose\ \ \ \ \ \ \ oxygen\\ dioxide

This oxygen is necessary for terrestrial and aquatic animals for respiration. Therefore, water breaks down into oxygen by the process of photosynthesis, hence water plays important role in respiration in living beings.
