Answer:
Option-C
Explanation:
The process of muscle contraction and relaxation is very complex and involves the electrical signals, calcium ions, ATP, proteins- actin, myosin, troponin, tropomyosin, and many others.
The process of muscle contraction begins when the neural signals lead to the release of the sarcoplasmic calcium ions and then calcium binds to troponin and allows the binding of the tropomyosin and formation of cross-bridge.
The muscle relaxes when the signals from the brain stop the release of the calcium ions from the sarcoplasmic reticulum and the released ions are pumped back in the reticulum.
Thus, Option-C is the correct answer.
Answer:
Sort of, true.
Explanation:
Cloning is when you take the DNA of a somatic cell of the animal you are trying to clone and add it to an embryo. It will then develop into a baby with the same DNA as the other animal.
(but in my opinion, you're just giving the test animal a sibling.)
When referring to knowing where to find something when you need it you mean that you do not need a memorization of all things, you just need a source to find it when in need. I hope this answer suited your needs.
