DNA can illustrate that evolution has occurred since in the process of natural selection advantegeous genes or traits have been selected to pass on through generations and further more evolve as long as the species survies and is successful in reproducing.
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.
Answer: food and drug administration
Explanation:
Based on this diagram, the organism is classified based on some similarities. In the upper-division, the similarities should be more general in the lower division, the similarities will be more specific. It was mostly based on an organ, for example: vertebrate.
An organism with the same phylum could be put in a different order.
But the organism with the same order should have the same phylum and class too since the order is located below the phylum. Those similarities are tightly correlated with the evolutionary relationship.
