Explanation:
I think it is: acetylcholine (neurotransmitter) - motor neuron - contract
second question: diffusion because of opening of ca2+ channels
There are choices for this question namely:
a. What is your name and where do you live?
b. How much poison did you swallow?
c. How long have you been feeling this way?
<span>d. What have you recently had to eat or drink?
</span>
The correct answer is "what have you recently had to eat or drink". This will confirm the suspicion by first ruling out potential reactive foods or drinks that may have caused a similar reaction (i.e. allergic reactions). If that is ruled out, then the probing about the history of intake of poison will come next in the interview.
I would say your answer is <span><span>The Earth’s surface is responsible for a small fraction of heat radiation to space</span>

Answer:
Water has a high Cohesion because of Hydrogen bonding. This is important as transport of water in the Xylem in plants relies on water being pulled up. Cohesion also gives the water a high surface tension, allowing small organisms, such as Pond Skaters, to walk along it.
Explanation:
Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions.
Plants obtain the hydrogen they need from water molecules. Don't try to feed your plant hydrogen gas -- your plant wouldn't know what to do with it if you did. As long as they have water, plants can readily obtain all the hydrogen they need. :)
