The First step in DNA replication is the unzipping the two strands. This process is carried out by the DNA helicase
The total magnification of a compound light microscope can be calculated by the product of the ocular lens and the objective lens magnifications which would be 10 x 40 = 400x.
The total magnification would be 400x.
Answer:
At a level in the spinal cord
Explanation:
The gate theory was elaborated in 1965 by P.D. Wall and r. Melzack, to explain the influence of tactile skin stimulation on pain relief. It essentially admits that there exists in the medullar posterior horns (located behind the central canal of the spinal cord) a gate-acting neural mechanism that can control the passage of nerve impulses transmitted from the peripheral fibers to the CNS through the medulla.
The gate regulates the influx of nociceptive impulses even before a perception of pain is created. The variation in the passage of action potentials (nociceptive) that the gate produces is determined by the activity of the thick (A-alpha and A-beta) and thin (A-delta and C) fibers, as well as cognitive influences.

Answer:
Rainforests provide us with plenty of trees and without trees there is no reducing carbon dioxide. If there were no trees, humans and animals will be taking up all the oxygen and making carbon dioxide and there is nothing to change that carbon dioxide . Humans and animals NEED oxygen to survive so if the earth is filled with carbon dioxide, every animal and human will die. Therefore, breaking the food chain. And in the end, everything will die.
