Answer:
C. Atomic Number
Explanation:
Atomic number, also known as proton number, never changes. Therefore it allows us to identify each atom.
Answer:
The correct answer is option (C) "After splitting ATP, a protein changes shape to pump ions across a membrane".
Explanation:
Adenosine triphosphate (ATP) is an organic chemical molecule considered the "molecular unit of currency" of intracellular energy transfer, for the high level of energy that is released when ATP is breakdown into adenosine diphosphate (ADP). ATP provides energy to drive many processes in living cells. One example of how the chemical potential energy of this molecule is turned into work is that after splitting ATP, a protein changes shape to pump ions across a membrane. The energy of the splitting of ATP into ADP will provide energy for the protein being able to change shape, resulting in pumping ions across a membrane.
When Hana pours the mixture through a filter,
she will likely to collect a solution of salt in water that passes through the
filter. <span>The activity shows the split-up of solids that
are not soluble from a liquid by means of what we called filtration. It can be
used to separate solids that are not soluble from a liquid, or a precipitate
from the reaction mixture that it made. </span>
The answer will be B. It is common sense
