Explanation:
In science, research questions are generally derived from the observation of phenomena. Also, hypotheses that represent general statements that have not been tested are formulated in such a way that they can be falsified. Hence, for each of the observations in the illustration, the question and their respective hypothesis would be as follows:
1. Observation: a teenager observed that he had three new pimples the night after eating a chocolate bar.
Question: Do chocolate bars cause pimples in teenagers?
Hypothesis: If teenagers eat chocolate bars, they might get pimples.
2. See the attached image
3. Observation: A little boy observed the leaves on trees changed colors when the temperature was lower.
Question: Do lower temperatures cause tree leaves to change color?
Hypothesis: If the ambient temperatures of trees are lowered, their leaves might change color.

Option B, It was made in stars that lived before the solar system formed.
Explanation:
Almost all the carbon that exists today with in the living organisms was produced in the stars. When these stars exploded during the big bang theory all the carbon within hem was introduced in the environment of earth some billions of years ago.

Cyanobacteria is responsible for generation of oxygen on planet earth and thus option D is in correct.
Answer:
sunlight
Explanation:
Undergrowth plants can be defined as the undergrowth or undergrowth that is found within tropical rainforests, also occurring in temperate forests, which forms a vital ecological niche in the forest ecosystem to which it belongs. In this highly humid system shaded by dense upper vegetation predominates the trees, shrubs, terrestrial epiphytes, mosses, fungi and other hundreds of hydrophilic species (which need a humid environment), forming exceptional and specific conditions for the maintenance of thousands of animals. .
As you may already know, plants need a lot of sunlight to stay alive. Undergrowth plants, however, are constantly shaded by tall planes, which could be a problem if these plants had not developed adaptive mechanisms to capture and need limited sunlight.
