D because just because of all the other effects it has no salt effect on the ocean
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.
Explanation: Natural gas is a limited resource. Natural gas is in the fossil fuel family and it's underground. I think it's pretty plentiful meaning that there's a lot in the United States of America. Many people use it for home heating instead of heating oil. Some people have oil trucks where the oil truck has to come and deliver oil to them.
So, natural gas is limited resource because it's a fossil fuel and it gives off emissions. It's in the ground and it's from years of decaying stuff. It's not like solar or wind power, it's a limited resource.

First, let calculate the volume of the rod shaped-bacteria:
S = length of the bacteria * surface of its side = 4.1 * (0.45 *0.45 * 3.14) = 2.6 µm3
Now, let's convert the moles into molecules (with Avogadro's law):
0.0037mol/L = 0.0037 * 6.023 *10^23 = 2.22 *10^21 molecules / L
Now let's convert The volume and the concetrnation into µm3 (molecules / µm3)
1 L = 1 dm3 = 1000 cm3 = 1000000 mm3 = 10^9 µm3
so 2.22 *10^21 molecules / L = 2.22 10^ 12 molecules / µm3
The answer is 2.22 10^ 12 molecules / µm3
