Answer:
A) the concentration of calcium ions in the sarcoplasm of a resting muscle
Explanation:
Sarcoplasmic reticulum is a system of the membranous sac that is present around each myofibril and is filled with calcium ions. When muscles are in the resting stage, calcium ions are stored in the sarcoplasmic reticulum.
As the muscle action potential triggers change in voltage-gated calcium ion channels of the sarcoplasmic reticulum, the channels are opened to release the calcium ions in the sarcoplasm. Increased calcium ion levels in sarcoplasm make the muscle fibers to contract.
Removal of acetylcholine from the synaptic cleft ends the production of muscle action potential and calcium ions are moved back from the sarcoplasmic reticulum.
Hence, lower levels of calcium ions are maintained in sarcoplasm when the muscles are in the resting stage.
Circulatory System because it carries the blood throughout the body.
1. meiosis II is quite similar to mitosis, in that the sister chromosomes are split during anaphase II in both processes
2. the stages of cell division (prophase, metaphase, anaphase, and telophase) are practically the same in both meiosis and mitosis - there are only a couple of tiny differences between them
B. Cloning because the selections don’t make sense
