That would be B. From energy in photons.

Photons(from sunlight) give energy to electrons and “excite” them(sending them to a higher energy level). Electrons can then release this energy and excite other electrons in other chlorophyll molecules.

AnnZ [28]

Answer:

The correct answer is D) Fissures

Explanation:

Karst is a topography or landform that is created by the dissolution of soluble rocks beneath the surface by waters from the surface or below.

Fissures are formed when because of earth movements there is the occurrence of a long, narrow opening, in the earth.

Artesian springs refer to the water coming out through these cracks or openings in the earth onto the surface of the Karst topography.

Based on the information in the graph, which blood type is most likely to be in shortest supply during an emergency?
Maksim231197 [3]
While there is no graph provided and I cannot find the graph online, I will base my answer through theory. 

In theory, the most common blood type is O+, followed by A+, then B+, then AB+. Rh negative blood is deemed to be rare. While the most common blood type is O+, the same blood type is also called the "universal donor" as a type O+ blood has no antigens attached in red blood cells therefore the probability of adverse reactions (i.e. hemolytic reactions) when transfused to other blood types are close to nil. In an emergency situation, wherein there is not enough time to do proper crossmatching, blood type O+ can be used therefore supplies of blood type O+ are easily depleted.
