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:
The animals could change it. For example, a bunny could dig a hole in the ground, making a home for other animals inside of it, too, changing the animals' living environment.
Or natural disasters could change their environment, too. For example, if a landslide occurred and covered a pond, frogs and snakes could lose their living areas and food, which would make them have to move to a different area, changing another ecosystem.
The antibodies are very unspecific
