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.

Immotile flowering plants accomplish fertilization with the help of Insects and other pollen from organisms that carry pollen to other flowers.
Explanation:
- The transfer of pollen from anther to the stigma of flower is called pollination.
- Pollination is of two types: a) Self pollination b) cross-pollination
- Transfer of pollen from anther to the stigma of same flower or flower of same plant is called self pollination.
- Transfer of pollen from anther to the stigma of different plant is called Cross-pollination.
- Pollination is the process by which angiosperms carry out sexual reproduction.
- Since, plants are immobile they need some agents for pollination like, <u>insects birds, wind, water etc </u>
