Answer: An inherited trait that makes an individual different from other members of its species is called a variation.
The best answer is A.
The shape of a protein is determined by its primary structure. The primary structure is the sequence of amino acids in each polypeptide chain which make up a protein.
The sequence of amino acids is basically a list of amino acids that are linked to each other to form a chain which is known as a polypeptide chain.
The structure of the finished protein will depend largely on the first (primary) chain of amino acids to be produced to make up that protein.
Answer: C. The red blood cells released water through osmosis. The release of water helped the blood cells keep a similar concentration of solutes as the outside solution.
Explanation:
Osmosis is a process whereby water molecules move from an area where they are in higher concentration than a solute to an area where they are in lower concentration. They do this by moving through a selectively-permeable membrane.
With sugar added to the solution, the water in the red blood cells will have a higher concentration of water in the cells than the solution so water molecules will move from the cell - through the cell membrane - to the solution. They will keep doing so till the concentration of solutes are more or less similar in both the cells and the solution.
