What is what kinda confused here
Answer:
Botulinum is a toxin that can be used to cure wrinkles in human beings by injecting it in very small concentrations and it works in preventing the signals from the nerve cells to muscles and thus paralyzing them by stopping wrinkle formation.
Wrinkles are caused by the contraction of muscles and this neurotransmitter does not allows the muscles to contract. In order to contract nerves release a chemical messenger called as acetycholine. This neurotransmitter is found at the junction where the nerve cell reaches the muscle cell. This causes contraction of muscles.
Injecting botulinum prevents the release of acetylcholine which prevents the contraction of muscle, causing reduction in wrinkles and muscles become stiff.
12C, 13C,and 14C are called isotopes because they are all the same element
Answer:
Molecules.
Explanation:
Molecules are the items that attach on the inside of the mineral to give the mineral its shape. The molecule of a mineral is a crystal three-dimensional regular structure (arrangement) of chemical particles that are bonded together and determines its shape.
Due to the fact that, these molecules are structurally arranged or ordered and are repeated by different symmetrical and translational operations they determine the shape of minerals.
