Based on what you have learned, what kinds of living and nonliving things do you think a marine biologist studies? what are some questions that biologists might ask about the living things they study?

Explanation:

A marine biologist study organisms from minute phytoplanktons to huge and gigantic blue whale. A marine ecosystem contains thousands of species of organisms that are study topic of a marine biologist.

Marine biologists study the interaction of these species with their environment. The non-living things that scientific study is about the effect of change in temperature, pH, oxygen quantity, light, acidity, salinity on marine species.

Some questions that biologist ask about living things they study are :

- how many marine species are in the endangered list?

- what is the role of a species in its ecosystem?

-how the extinction of a species affects the food chain in the ecosystem?

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
