Answer:
20 minutes
Explanation:
Divide distance by speed to get time
D/S = t
350/17.5 = 20

Answer:
A- Acetylcholine is released by axon terminals of the motor neuron.
Explanation:
The general mechanism of muscle contraction can be explained as follows:
a) The action potential which is generated, travels along the motor nerve to its ends on muscle fiber (or motor end plate) at the neuro-muscular junction.
b) The nerve endings then secrete small amounts of neurotransmitter called acetylcholine.
c) The actylecholine binds to the receptors on the membrane of muscle fiber and opens the voltage gated sodium channels.
d) Opening of these channels leads to flow of large quantities of sodium ions into the muscle fiber which ultimately results in initiation of action potential in muscle fiber.
e) This action potential depolarizes the fiber including the T-tubules, triggering the release of calcium ions from sarcoplasmic reticulum.
f) The calcium ions thus released initiated the process of muscle contraction.
Plate tectonics have the potential to affect organic evolution due to the fact that the movement of these plates may well cause land masses to shift and cause a change in climate as a result

<span>Answer:
Bacterial DNA is directly exposed to the cytoplasm, which has the ribosomes on which protein synthesis takes place. As the mRNA molecule proceeds for synthesis, ribosomes immediately attach to the free 6' end of the RNA transcript and begin translating it into protein.</span>
Answer:
Given that a colorimeter is an instrument used for chemical analysis by comparing a liquid’s color with standard colors. In an experiment, a scientist used two calorimeters and noted the readings. The first colorimeter showed consistent readings that were five points lower than the actual reading. The second colorimeter provided readings that were the same as the actual reading.
Though consistent, the first colorimeter has a zero error of -5.
Hence whenever first calorimeter is used this adjustment to be made i.e. actual reading +5 should be made to get correct reading
But second can be used as such taking the reading as correct.
