Answer:
D.The light-dependent reactions absorb sunlight and transfer the energy to electrons.
Explanation:
Firstly, the organelle that was described as small green organelle inside a cell as noticed by Quinlin is the CHLOROPLAST. Chloroplast is an organelle present in the cells of green plants, in fact, it makes plants green. Chloroplast is the organelle where the unique process of PHOTOSYNTHESIS occurs in plant cells.
However, the photosynthetic process is divided into stages namely: light-dependent and light-independent stages. The light dependent stage, which involves the production of ATP (energy carrier) and NADPH (electron carrier), must PRECEDE the light independent stage or Calvin cycle. Chloroplast contains a pigment called CHLOROPHYLL, which absorbs light energy from the SUN in order to power the light dependent stage of photosynthesis.
Hence, the light-dependent reactions, which absorb sunlight and transfer the energy to electrons must occur first in the organelle.
An adaptation occurs when a species is set through a new constraint. This can be change in climate, defense mechanisms, food source, etc. Which will have to occur before an adaptation is made. For an example: in North America the climate slightly swifted. This meant smaller mammals such as rabbits would need to have a thicker coat of fur or shelter. Let's say all the thin furred rabbits died and all that remained were the thick furred rabbits. Over a span of time the rabbits have adapted through the climate. Meaning most of the population is thick furred through their DNA. Conclusively, it's a genetic characteristic that can happen very rapidly or slowly.
I hope this solved your question!

Explanation:
Hello. This question is incomplete. The full question is:
John Allen is scheduled for a diagnosis on tooth #20. This is Mr. Allen's first time to the endodontist, and his subjective comments describe pain when chewing on the affected side and a constant dull pain lasting for approximately a week.
How do you think Mr. Allan knew ro come to a endodentist for dental treatment?
Answer:
Mr. Allan learned that he needed treatment with an endodentist through consultation with a general dentist.
Explanation:
It is likely that when Mr. Allan felt discomfort in the tooth, he made an appointment with the general dentist. Through the analysis of Mr. Allan's case, the general dentist realized that Mr. Allan had a very specific problem and that he should be treated with a professional, someone who could deal with the problem directly and more effectively. For this reason, Mr. Allan's dentist suggested that he look for an endodentist who could help him, since Mr. Allan was having problems with dental pulp.
