Answer:
Enhancer sequence.
Explanation:
Enhancers may be defined as the transcription factors that are used to enhance or increase the activity of the gene. Enhancers bind with the transcription factors to regulate and increase its expression.
The mutation in the enhancers decrease the transcription of of the other gene. These sequences lies far away from the transcription site but still known to increase the rate of transcription. Hence, the mutation has been done in the enhancer sequences.
Thus, the correct answer is option (b).
Answer:
A group of parasites called myxozoans have traditionally been considered simple multicellular protists. However, because these organisms possess stinging cells, some scientists consider them to be animals in the phylum that is named for such cells, the <u>cnidarians</u>.
Explanation:
Cnidarians are animals with radial symmetry, that is, their bodies can be divided, by different planes, into equal parts. It includes hydras, jellyfish, anemones and marine corals. Its body is a kind of sac with an opening (the mouth) surrounded by a circle of tentacles. Some have a dominant jellyfish phase, others polyp, or both. They present defensive nematocysts with stinging action.
Answer:
Renewable resources make cleaner energy. It takes longer to replenish renewable resources. Renewable resources are more easily located and harvested. It often costs much less to produce energy from renewable resources.
It's both! Scientists really can't agree on it.
