Answer:
A parasites is known to cause malformations, but only when it attacks tadpoles at a certain point in their development. Predators can cause missing or shortened limbs, as a partially eaten tadpoles regenerate lost tissues.
Explanation:
Respiration is the type of biological exercise that raises Co₂ concentration in the atmosphere.
Explanation:
RESPIRATION is said to be the basic biological and metabolic process that is essential for all living beings for their survival and growth with nourishment.
Cells are the basic unit of living organisms that undergo cellular respiration. In this process, oxygen is in taken and carbon dioxide is respired out which adds the concentration of the carbon dioxide from the atmosphere.
In the process of respiration, the living cells of the organism produce energy by the intake of oxygen for the oxidation of complex organic substances and expires out the carbon dioxide.
Answer:
Carbon dioxide, which is naturally in the atmosphere, dissolves into seawater. Water and carbon dioxide combine to form carbonic acid (H2CO3), a weak acid that breaks (or “dissociates”) into hydrogen ions (H+) and bicarbonate ions (HCO3-).

D
