Answer:
Photosynthesis serves as a process of transferring carbon between the atmosphere and the biosphere by using carbon dioxide present in the atmosphere to produce sugars found in plants.
Note: The model is found in the attachment below
Explanation:
The atmosphere is the layer of gases forming an envelop around the earth. The earth's atmosphere is composed of mainly nitrogen and oxygen as well as other gases such as carbon dioxide and water vapor.
The biosphere refers to the regions of the earth's surface on which living organisms can be found. It includes the land, air and water.
Carbon dioxide is cycled between the atmosphere and the biosphere by the process of photosynthesis which is the process by which green plants manufacture their food with the aid of energy from sunlight.
From the model, in the first stage, energy of sunlight is trapped by light-dependent reactions and is used it to make ATP and NADPH. During the second stage, the light-independent reactions use ATP and NADPH reduce carbon dioxide from the atmosphere to sugars and ADP and NADP⁺.
Thus, photosynthesis serves as a process of transferring carbon between the atmosphere and the biosphere.
Answer:
C
Explanation:
Volcanic eruption spews volcanic ash into the atmosphere that lingers and blocks out sunlight for months. This causes photoautotrophs to decrease in population numbers due to the inability to photosynthesize. This will negatively affect the heterotrophs that depend on the autotrophs for energy.
Answer:
B
Explanation:
There are usually dominant and recessive alleles. The dominant alleles mask the expression of the recessive allele. Therefore, whenever an offspring has a dominant allele of a gene, it will be expressed whether in homozygous or heterozygous form.
Answer:
B
Explanation:
A limiting factor is an element whose abundance affects the growth and distribution of a population of a species in an environment. In this case, increasing the levels of Nitrogen in the environment increases the population size and vice versa.

I would say C. eliminating government funding of research. without finding, scientists can't experiment, therefore all their research remains purely theoretical and isn't considered a discovery.
Hope this helps!
In the year 1850, Rudolf Virchow was studying cells under a microscope, when he observed that cells were dividing and forming new cells. Realizing what he had observed, he understood that living cells reproduce new cells through division. Basing on his conclusion and realization, Virchow proposed that living cells came only from the other living cells.
