Letter D. is the answer. Carbon, nitrogen, and oxygen cycles are bio-geochemical cycles.
Biogeochemical cycle or cycling of substances or substance turnover is a pathway by which a chemical substance moves through biotic and abiotic compartments of the Earth: lithosphere, atmosphere, and hydrosphere. The term biogeochemical tells that biological (bio) and geological (geo) and chemical factors are all involved. The circulation of chemical nutrients such as carbon, nitrogen, oxygen, phosphorus, calcium and water by biological and physical world constitute the biogeochemical cycles. As an effect, the element is recycled, although in some cycles there may be reservoirs where the element is accumulated/ held for a long period like ocean or lake for water.

Why does maltose have both alpha and beta anomers?
BabaBlast [244]

Answer:

Maltose is a disaccharide sugar made up of two units of glucose.

In cyclic structure, the glucose exists in two anomeric forms; alpha and beta.

These glucose units can either joined by α (1→4) glycosidic bond or by β (1→4) glycosidic bond.

Thus, the maltose exists in two anomeric form alpha and beta.

Norma-Jean [14]

Answer:

The rate of photosynthesis was more than the rate of respiration

Explanation:

Photosynthesis has to do with the synthesis of sugar molecules from inorganic products such as water and carbon dioxide. Respiration on the other hand has to do with breaking down of the sugar molecule from photosynthesis to release the energy locked up in the sugar for various metabolic processes in the plant's body.

<em>If both processes are balanced, there will be no net sugar production. Hence, if an excess of sugar produced fossil fuels, it thus means that there was net production of sugar in the past. The rate of photosynthesis was more than the rate of respiration in the past.</em>

(honest question) How come whenever archaeologists uncover human remains they are always male or female and not any of the other
Doss [256]

I think you're confused. There are only two sexes, male and female. Sex is what you were biologically born as from birth, while gender is what you choose to identify as. Gender is a choice, sex isn't. They couldn't discover any other genders because at the time they probably didn't even know what gender was like three thousand years ago, therefore they couldn't look like a different gender.
