Answer:
The sarcoplasmic reticulum contain calcium ions in skeletal muscles which is involved in muscle contraction.
Explanation:
Sarcoplasmic reticulum is an intracellular system of closed saclike membranes involved in the storage of calcium in skeletal muscle cells. The sarcoplasmic reticulum regulates the concentration of calcium and determine muscle contraction.
Answer:
The correct option is C.
Explanation:
There are three modes of heat conduction, these are conduction, convection and radiation. Heat transfer by conduction usually involves the movement of heat through solid substances. For instance, in the scenario given in this question, the warm surface is the solid substance through which heat is passed to the insects' bodies. Thus, conduction requires direct contact.
Heat transfer by convection method usually involves the movement of heat through liquids or gases while radiation can occur in vacuum.
