The heart and the arteries of a person, both contracts to pump the blood throughout the body. The aorta, which is the largest artery of the human body, pumps the blood from the heart to the entire body of a person. The oxygen-rich blood is pumped out of the left ventricle when its contraction into the aorta, from where it is transported to the whole body.
Hence, the given statement is true.
 
        
                    
             
        
        
        
Cell division begins along the cell's equator, between the two chromosomal poles that form during nuclear division. Microflients help the cell lay down new membrane and divide it into two daughter cells.

Answer:
If a protein or molecule is taken up by the cell and must be digested it will make use of <u>lysosomes</u>.
Explanation:
Lysosomes are membrane-bound organelles that have a wide range of functions but their main 'job' is to break down large molecules into smaller molecules or to digest molecules that are present in excessive or unnecessary amounts. This is why <u>they contain important digestive enzymes known as hydrolitic enzymes.</u>
Lysosomes can break down, for example, large proteins into amino acids to provide the cell with the necessary nutrients.
