Answer:
A
Explanation:
The components of salt water are chemically combined together and looks throughout, forming a homogeneous mixture.
Answer:
The initial step in the formation of an aminoacyl-tRNA is activation of the amino acid by reaction with ATP
Explanation:
In protein synthesis, the first step involves the formation of an aminoacyl-tRNA. This reaction is catalyzed by the the Mg²⁺-dependent enzymes known as aminoacyl t-RNA synthetases and occurs in two steps.
The first step of the reaction of the formation of an aminoacyl-tRNA is the activation of the amino acid by the attachment of an AMP molecule formed from the hydrolysis of ATP to AMP and pyrophosphate. The aminoacyl adenylate intermediate is bound to the enzyme in this initial step. Subsequently, in the second step of the activation of the amino acid, the aminoacyl adenylate intermediate is then transferred to its specific tRNA. The pyrophosphate formed in the first step is hydrolyzed to 2 phosphate molecules by a pyrophosphatase.
The overall reaction step is illustrated below:
Amino acid + tRNA + ATP -----> aminoacyl-tRNA +AMP + 2Pi

The answer should be RNA but i think DNA would work too
Answer: All cells must show movement
Explanation:
The cell Theory states that:
- The cell is the structural and functional unit of life
- All living organisms are made up of cells
- All cells come from previously existing cells
- There is no life apart from the life of cells
- All living things are either with a single cell (unicellular) or a group of cells (multicellular)
Thus, the statement "All cells must show movement" is not a statement of the cell theory.
