ANSWER: C. Complementary base pairing occurs only between the probe and the target gene.
Biology is the study of life so a Biologist would study biology: the study of life and living things.
A serum calcium concentration of this range only means
that the cancer must be suspected to be a malignant one. So the nurse should
suspect that the malignancy of the cancer is what is causing the electrolyte imbalance
of the patient.
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.
