Answer: The statement is true
Explanation:
Natural selection, as its name implies refers to the choice of certain favorable traits such as resistance to diseases, bigger fruit size etc above lesser favorable traits such as easy susceptibility to diseases, small fruit size etc.
Hence, nature allows the traits that will help living organisms survive best in their environment to be passed down to new offsprings while it eliminates all other traits.
Thus, the statement is true

Malpighian tubules<span> remove wastes from insects by producing urine and solid nitrogenous waste, which are then excreted from the body.</span>
