RNA polymerase (green) synthesizes RNA by following a strand of DNA. RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, duyring the process of transcription.
Answer:
Explanation:
Make an observation.
Ask a question.
Form a hypothesis, or testable explanation.
Make a prediction based on the hypothesis.
Test the prediction.
Iterate: use the results to make new hypotheses or predictions.
A.Petals. Usually, petals are the most prominent part of a flower structure, owing to their vivid color (in most flower examples) and sometimes scent. Their main function is to attract pollinators and also protect the inner reproductive structures of a flower. In some flowers, petals are absent or reduced.
B.Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther. Anther: The part of the stamen where pollen is produced. Pistil: The ovule producing part of a flower. The ovary often supports a long style, topped by a stigma.
C.Pistil interaction precedes fertilization in the flower. Important changes occur in the pistil, which play a role supporting, but also controlling pollen-tube growth
D. The ovule is the organ that forms the seeds of flowering plants. It is borne in the ovary of the flower and consists of nucellus protected by integuments, precursors of embryo/endosperm, and seed coat, respectively.
The answer is D. This is an exmaple of incomplete dominance. Red and blue make purple. Because there is no purple alleles, C is false. Because there you can only have 2 alleles total B is false. A is false because having two red alleles makes a red flower.
