Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.
The human body comprises of more than 600 muscles differentiated in three classifications, and all are under the control of the nervous system. The activities like picking up a dropped pen or leaning over incorporate the combined effort of various muscle groups.
The alert mind relays this instruction to the central nervous system that conducts it in the form of electrical impulses. These are then mediated via the somatic segment of the peripheral nervous system to the nerves accountable for monitoring the essential muscles.
When the signals arrive, a chemical known as acetylcholine gets discharged from the nerve terminals, activating the membranes of muscle fibers and making them to contract. The receptors present in the muscles provide the brain with the instruction regarding the movement and position of the body, the brain monitors the contraction of skeletal muscles.
Answer:
D) H in glucose and water; O in O2
Explanation:
In green photosynthesizing plants, photolysis occurs during the light-dependent phase. Photolysis is the splitting of the water molecule in the presence of sunlight. The oxygen atom of water molecules forms oxygen gas that is released as a by-product of photosynthesis. Photolysis also releases electrons and protons from water molecules that finally reduce the NADP into NADPH.
The light-independent phase of photosynthesis fixes reduces CO2 into glucose. NADPH serves as reducing power during the light-independent chemical reactions and therefore, the H atoms from water molecules are incorporated into glucose and water molecules formed during light-independent reactions of photosynthesis.

Neurotransmitters are intracellular messengers that mediate transmission of impulses in the nerve cells whereas hormones regulates the functioning of various body organs. Norepinephrine and epinephrine are both hormones and neurotransmitters since they transmit impulses and at the same time regulate activity of organs in the body.
