Answer: calcium is released from the sarcoplasmic reticulum
Explanation:
Muscle contraction is the stimulation of sites that produce stress within muscle fibres.
Calcium ions bind to tropomyosin in inducing muscle fibre contraction, exposing active site for Crossbridge formation on actin. Then ATP binds to myosin, transferring the myosin to its high-energy state, freeing the myosin head from the active actin site. Triggering tension-generating sites within muscle fibres.
Hence, the contraction process is initiated with teh relaease of calcium from sarcoplasmic reticulum.

I had to look for the options and here is my answer:
The lipids that could be classified as a precursor for both testosterone and Vitamin D is cholesterol. It has been studied that Vitamin D can have a direct effect on the levels of cholesterol in the body especially for women who are obese and postmenopausal.
The answer is A. detritus.
Detritus typically includes the bodies or fragments of bodies of dead organisms, and fecal material. Detritus typically hosts communities of microorganisms that colonize and decompose (i.e. remineralize) it. In terrestrial ecosystems it is present as leaf litter and other organic matter that is intermixed with soil, which is denominated "soil organic matter".
