Answer:
<u>acetylcholine</u>
Explanation:
In the pre-synaptic knob there are vesicles which contain a transmitter substance called acetylcholine. When an impulse reaches the synaptic knob, it stimulates the vesicles to move towards the pre-synaptic membrane releasing the acetylcholine.
The transmitter substance makes the membrane permeable. The neuromuscular junction contains the sensory neurone(afferent), motor neurones(efferent) and the relay neurones(connector).
The answer is all of the above
B - They have different arrangements of atoms.
Answer:
The correct answer would be "Can prevent genetic diseases".
Cloning refers to the process of making an identical copy of organism, cell or DNA fragments.
One of the applications of cloning is eradication or prevention of genetic diseases.
It is done by isolating the correct or functional gene and make copies of it in in-vitro conditions.
The gene or DNA fragment is then inserted back into the cell.
With advancement in cloning process and understanding of stem cells, cloning process also favors tissues and organ harvesting which also help in reducing diseases.
The carbon fixation occurs in the stroma, which is the colourless fluid that bathes the grana inside the chloroplast. It is in the stroma that the biochemical <span>reactions of reduction take place, one of them being</span><span> </span><span>carbon fixation. This is a light-independent reaction that is part of Calvin cycle. The stroma is where the enzymes that catalyse these reactions can be found.</span>
