Answer:

A. Obligate

Explanation:

An obligate relationship is one where both organisms are interdependent with one another in a way that one cannot survive without the other.

A parasitic relationship is where one organism benefits, and the other is harmed.

A mutualistic relationship is one where both organisms "work together," therefore benefiting one another.

A facultative relationship is where both species benefit off of one another, but are not fully dependent on one another to the point they cannot survive without their symbotic partner.

Using a microscope, Quinlin notices a small green organelle inside a cell. Which of the following is most likely to occur first
jek_recluse [69]

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.
