Answer:
The relative size of the crest height and width of offspring raised in the tank without chemical cues is lower as compared to the parent Daphnia.
Explanation:
The size of the crest of Daphnia is directly related to the chemical cues secreted by the Notonecta. If the water has Notonecta , the size of the crest of Daphnia is increases because the crest is sensitive with the release of the chemical cues of Notonecta. So if the water has no chemical cues, the size of the crest height and width of offspring is lower as compared to the parent Daphnia.
GMO I think. Genetically modified organisms.
Answer:
The correct answer is option C. up-regulation.
Explanation:
When the body requires the increased level of the hormone, target cells increase the synthesis of more receptors on the cell surface of the target organ. This process is known as the up-regulation of the receptors for the hormone.
Up-regulation is an increase in the receptors present on the cell surface of target cells so that cells can easily bind to the hormone. Up-regulation makes the cells increase the sensitivity to a hormone.
Thus, the correct answer is option C up-regulation.
