Answer:
relaxes
Explanation:
Acetylcholine is the substance responsible for the transmission of nerve impulses from pre-postganglionic neurons, in the ganglia of the autonomic nervous system. At the level of the parasympathetic nervous system, the transmission between the postganglionic neuron and the effector organ also mediates. In addition, it is the mediator of the nerve transmission of the terminal motor plate.
There are large differences in the effects that Acetylcholine triggers at different cholinergic transmission sites
Intra-arterial injection near Acetylcholine produces muscle contraction similar to that caused by motor nerve stimulation. Decreased resting potential in isolated intestinal muscle and increased frequency of spike production, accompanied by increased tension. In the cardiac conduction system, nodes S-A and A-V, it produces inhibition and hyperpolarization of the fiber membrane; and pronounced decrease in depolarization speed. Central regulation of extrapyramidal motor function. Exciting effect of the basal ganglia that counteracts the inhibitory action of Dopamine. Although cholinergic innervation of blood vessels is limited, cholinergic muscarinic receptors occur in sympathetic vasoconstrictor nerves. The vasodilator effect on isolated blood vessels requires the presence of an intact endothelium. The activation of muscarinic receptors causes the release of a vasodilator substance - <u>relaxing factor derived from the endothelium - that diffuses to the smooth muscle producing </u><u>relaxation</u><u>.</u>
Find the attachment for the answer.
Note: I have added the complete question in the attachment.
The correct answer is: D. The red blood cells were placed in a hypotonic solution. Water moved from the outside of the cells to the inside of the cells until the cells burst.
Hypotonic solution can be described as solution that has less solute and more water (H2O) than another solution. In order to maintain homeostasis, the water will move (via osmosis) into the cell, through the semipermeable membrane of the red blood cell.
Answer:
Option D, The work done by each force is negative
Explanation:
When both the forces are negative, then irrespective of which force is large or small, the net force will definitely negative. A negative force indicates reduction in kinetic energy of particle. Since mass is constant , it is the speed which reduces and produces negative work. Reduction in speed is contrasting to the statement give in the question. Hence, option D is not possible.
USLANTCOM had been active from 1947
to 1993 as a main U.S. Navy command, focused upon the wartime defence of the
Atlantic sea lanes against Soviet Union attack. After the end of the Cold War,
a 1993 reorganization gave the Command a new acronym, USACOM, and make United
States Army Forces Command and Air Combat Command under its authority. USJFCOM
was established in 1999 when the old United States Atlantic Command was change
its name and given a new mission: leading the transformation of the U.S.
military through experimentation and education.
