Answer:
<em>Light-dependent reactions</em>
<em></em>
Explanation:
Photosynthesis occurs in two stages: light-dependent reactions and light independent-reactions. This last stage is often called Calvin cycle.
The diagram shows reactions occurred in the thylakoid membranes which are located inside the chloroplasts. Therefore, we can identify that these reactions are the light-dependent reactions. During this part of photosynthesis, the energy from the sunlight is absorbed by a pigment called chlorophyl (Chl). Then, it is sequentially coverted into chemical energy stored in the form of molecules: NADPH (nitotinamide adenine dinucleotide phosphate) and ATP (adenosine triphosphate).
Answer:
The correct option is <em>B) Some wolves may have had variants in their digestion that allowed them to eat wheat, rice, barley, corn, and potatoes and so were able to survive with humans.</em>
Explanation:
Organism of a population might have genetic variations in them due to many reasons. The species of a population which are better adapted to live in a particular area are able to survive and produce more offsprings. As a result, that particular area increases in that genetic variant.
In the above scenario, some of the wolves had variants in their digestion which made them better adapted to live with the humans as they could eat wheat, rice etc. The wolves which did not have variants in their digestion couldn't survive in the human areas.

Answer:
c. recognize a member of their own species.
Explanation:
Imprinting is a form of social earning that occurs in a critical period based on early experience, in which an animal develop a sense of identity usually within few hours or days after birth.
In birds, for example in ducks, once an egg is hatched, the ducklings imprints on the first moving object they see which happens to be the mother. In other to keep track of the mother, they learn to respond to a characteristic sound that have been emitted by the mother. Through imprinting, they are able to distinguish their mother from the rest of the ducks. Imprintng helps birds to form an identity during early stage at birth, which helps them to recognize members of their own species.
Trees are examples of biotic factor which includes living things in which the size ranges from minute or small to large, referred to as micoorganism or macroorganism. Abiotic factors on the other hand, are non-living things which are soil, temperature and sunlight, in this case.
