Answer:

The correct answer is option C.

Explanation:

Phospholipase C comes in the category of membrane-associated enzymes, which plays an essential role in the cell physiology of eukaryotes, mainly in the process of signal transduction. One of the general features of the phospholipase C pathway is that it enhances the concentration of calcium within the cell's cytoplasm.  

With the stimulation of phospholipase C within a cell, calcium generally gets discharged from the intracellular compartments, which eventually results in the upsurge of calcium levels within the cell's cytoplasm.

Please help<br> Explain why a lack of gravity might cause muscles to weaken
Elodia [21]

Answer:

Lack of gravity causes you to use less work to move your muscles.

Explanation:

If on Earth your arm weighs 3 pounds, the muscle will only have to move 3 pounds of force. For example, if you were to go on the moon, your arm would have the same mass but there would be less gravity pulling it dow. So now your muscles only need to pull 1 pound. Over extended periods, you would be working less, thus not using your muscles to fullest potential and in result you would get weaker.

I think you forgot to give the options related to the question. So it becomes a bit hard to answer the question perfectly, still i would do my best and hope that it comes to your help. Prior to the ideas presented by Charles Darwin concerning evolution, several alternating theories had been developed and they included all but the DNA differences within a species lead to some individuals being better able to survive. This theory was developed after Darwin came up with his theory..
