<u>Answer</u>:
Potassium inside the cell and sodium out of the cell
<u>Explanation</u>:
The presence of the pump can be seen in plasma membrane of the animal cell. Which can be followed by the ATP, this pump pushes sodium and potassium in completely opposite direction that can be said as against the concentration gradient. In one cycle of this pump, two potassium are ingested inside the cell and three sodium are taken out from the cell. Due to more number of negatively charged proteins inside the cell, potassium ion contains more positive charge so pushed inside the cell. The potassium is pumped through the channels.
<span>The two factors that determine the shape of a protein </span><span><span>
1. </span> Primary structure. The sequence of amino acids. Amino acids are the building blocks of protein. It is a strong of linearity that can be thousands in length. Moreover, the formation of the amino acid and its system is influenced by its genes’ nucleotides arrangement. </span>
<span><span>2. </span>Hence the next factor is how is the structure of the amino acids bended and folded with itself that forms the certain protein molecule and forms the larger complex structure</span><span>

The answer is large jaw bone for muscle attachment.
Pelvic blades are rotated inward anyway, so it is not the right answer. Very long arms are characteristic of many other animals, as well as a thick rib cage is. This leaves a large j<span>aw bone for muscle attachment as the right answer. This trait is an adaptation to eating large quantities of food.</span>
