Answer:
Plants, algae, cyanobacteria, and etc.
Explanation:
<em>"Most </em><em>plants, most algae, and cyanobacteria perform photosynthesis</em><em>; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth."</em>

Answer:
d. Views could be used to make topographic maps of the area.
Explanation:
Satellite views helps the planners in choosing a location for the airport because it provides topographic maps of the area which contains all information about natural features of that area such as roads, railways, power transmission lines, contours, elevations, rivers and lakes. So the satellite images provides a great help to the planners to find out suitable place for the airport.
Answer:
b. Nucleotides
Explanation:
Nucleic acids are examples of structures formed from nucleotides. And in relation to the composition of DNA, we have the formation of the largest cellular macromolecule, all formed by nucleotides.
The nucleotide is a group formed by the association of 3 molecules - a nitrogen base, a phosphate group and a pentose glycide. Thus, we may have variations within these ligands, such as: in DNA we have the presence of pentose deoxyribose, while in RNA we have the presence of pentose ribose.
The nucleotides have differences in relation to its nitrogen base, which can be purine or pyrimidine. Purine bases vary in Adenine and Guanine, while pyrimidine bases are classified in Thymine, Uracil and Cytosine. Purine and pyrimidine bases are complementary and each have specific binders. Thus, we have that the purine base Adenina, binds with the pyrimidine bases Timina and Uracila, while the base Guanina binds exclusively to Cytosine and vice versa.
