Answer:
The correct answer is - 10³ seconds.
Explanation:
The nerve impulse is an electrical signal in which fluctuation in membrane potential occurs and forms an electrical signal that takes place that travels along the axon to the synapses.
Suppose a nerve impulse starts only when the first impulse ends according to the question so the one impulse last for the 10⁻³ second or 1 ms.
Thus, the nerve impulse fires per second will be equal to impulse generate in each second which is 1/10⁻³ = 10³.
Thus, the correct answer is - 10³ impulse per second or 1000 impulse per second.
Answer:
It is called the S-A node, or rather sinus node.
The answer is restriction enzymes. These staggered ends are important in recombination of DNA since they allow DNA strands with complementary sticky ends to be easily joined into one piece by DNA ligase. Other restriction enzymes produce blunt ends. These are harder to join by DNA ligase. An example of a restriction ezyme if EcoRI
