DNA replication needs to occur because existing cells divide to produce new ones . It needs to be copied before cell division so each new cell created can receive a new full set of “instructions”
The offspring will be all blue. The answer to your question is A. I hope that this is the answer that you were looking for and it has helped you.
DNA is transcribed to RNA, which is translated into proteins. So DNA is in charge of making proteins (this narrows it down to either A or D). When there is a change in a person's genetic information, it will not result in a contagious disease. Those are usually caused by bacteria or viruses. A change in DNA could potentially result in a genetic disease. Therefore, answer A is correct. Hope this helps! :)
There is a physical barrier (small village in a mountain valley) that does not let those traits to escape the region. In other words, the physical barriers prevent gene flow occurring. This is what makes that specific gene for polydactylism to be prevalent in that area.
hope this helped.
Answer:B stabilize the ecosystem
Explanation: Negetive feedback processes are initiated in the ecosystem to stabilize the ecosystem. These negative feedbacks counteract on a particular process im other to create an equilibrium in the entire ecosystem. A good example of negative feedback process is population control. In other to keep regulate and stabilize the ecosystem, predators and preys act to keep population of an environment in equilibrium so that the resources present, which are limited, can sustain the population.
