Answer: increase, increase
The term aerobic literally means "with oxygen", and refers to the use of oxygen by muscles for generating energy. An aerobic activity will increase the rate of heat so that it can pump more oxygenated blood because of increase in muscle activity, the need of oxygen of body also increases.
Hence, an aerobic activity is defined as one that increases the heart rate and increases the body's need for oxygen.

D. Digestive Enzymes
Answer:
Marine biology is the study of organisms that lives in the marine environment, the environment that found in sea and oceans. They also study the interaction between these organisms and their environment.
Marine biologists study both living and non-living things in their surroundings where they do research. The living things they study are marine organisms like fishes, sharks, whales, crustaceans, deep-sea organisms, sea plants, microbes and many more living creatures present in the marine environment.
They study their behavior, feeding habits, interaction with other organisms, their role in the ecosystem, mating behavior, etc.
The non-living things a marine biologist study are physical and chemical environment of marine habitat, geology of the area, concentration of salt, and other molecules that affect marine biology.
Answer:
(C).Rough endoplasmic reticulum
Explanation:
Endoplasmic reticulum (ER) is a membrane-bound cell organelle, present in eukaryotic cells. There are two types of endoplasmic reticulum, smooth ER and rough ER.
Rough ER contains ribosomes on its outer surface (side, which is in contact with cell cytosol), while in smooth ER surface, ribosomes are absent. This is because ribosomes provide platform for the process of protein synthesis or translation.
Proteins synthesized by ribosomes present in rough ER surface are then transported to it (rough ER) for sorting and post-transnational modifications.
Thus, the correct answer is option (C).
