Some organisms are microscopic and consist of only 1 cell
Chloroplasts are green pigment used in the process of photosynthesis found in leaves.
Leucoplasts are colourless and are the storehouse of minerals and other nutrients found in the roots of plants.
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.
True Marie biome is the largest of all the ecosystem
The appropriate response is field of genetics. Genetics is the investigation of qualities, hereditary variety, and heredity in living creatures. It is by and large considered a field of science, however, meets every now and again with numerous other life sciences and is firmly connected with the investigation of data frameworks.
