and is prevented in the absence of , which causes calcium to trigger contraction through a response with regulatory proteins.
and filaments of the fibrils glide into one another as a result of calcium diffusing in the cytoplasm, resulting in the of the complete muscle fiber. The SERCAs pump (Sarcoplasmic/endoplasmic reticulum calcium ATPase) actively pumps ions back into the sarcoplasmic reticulum when the action potential decays.

Answer:
Capsule
Explanation:
In many bacterial species, an extracellular layer composed of a polysaccharide especially a monosaccharide is produced around the cell wall of the bacteria. This extracellular layer is known as the slime layer or the capsule.
The capsule in bacteria serves many purposes like it protects the bacteria from the destruction by the white blood cell in the host, it enables the bacteria to adhere to the substrates and protect it.
In the plant group called the bryophytes also a capsule structure is present which grows in the sporophytic phase and encloses the spores, therefore, the capsule is considered the sporangium of the bryophytes.
Thus, the capsule is correct.
D. He showed how traits are passed between generations
Answer:
The mass number is the sum of protons and neutrons. This means to find the number of neutrons you subtract the number of protons from the mass number. On the periodic table, the atomic number is the number of protons, and the atomic mass is the mass number.
