Answer:
false thought ia ion of neon = clarity active
Explanation:

Answer:
Bind to the protein complex troponin.
Explanation:
Excitation of skeletal muscle caused by the calcium ions. During excitation of skeletal muscle, after calcium ions released into the cytosol, they bind to the protein complex known as troponin and causing substitutions in the protein complex.
These alterations permit protein to push out from the myosin-binding sites on the actin filament.
What do you mean I don’t understand this I could help but don’t understand
Paper burning is a form of a physical change known as combustion. The chemical bonds in between atoms holding them together are being changed with the heat, making it different on an atomic level.
Answer (3) is the most correct, although (2) is not to be ignored. (3) states the most abundant isotope Ti's average mass, which is certainly true. (2) is the total mass of all protons, neutrons, and electrons in an atom of Ti, which is true but has to be more specific in order to pinpoint exactly the 47.88 amu. (4) is incorrect because it is not of all the naturally occurring isotopes of Ti. (1) is incorrect because they forgot electrons.
