ANSWER ( Convergent plate boundaries )
At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.
What do you mean <span>It has been observed that certain species of insects which had not previously caused significant harm have become serious pests. the best explanation for this phenomenon is that the pesticide killed off predators which had previously held this species in check. a mutation occurred in the species. the pesticide increased the vigor of the species. was able to be used by the pest as an additional food source is also a reproductive for some insect species. </span><span />
Answer:
towards the inside hyperpolarising the neuron
Explanation:
GABA(gamma amino butyric acid) is an inhibitor neurotransimitter. When it attaches to the post-synaptic segment it causes an influx of anions that makes is harder to generate an action potential.
Answer:
<u>Option-</u> "If a flock’s beak type made it easier to pick up the available food, the flock grew."
Explanation:
- We can simplify the whole answer by having argument about the structure or alignment of the birds in a given way which provides more food sources or options for the 1st generation and then the third generation can be found in a more scattered form inside the herd, as there are no more food requirement as much was before.
The statement that it causes light to slow down significantly best describes the high index of refraction.
<u>Explanation:</u>
Index of refraction is the amount a medium will be refracting the incident light. As it is a measure of amount of light getting refracted, the medium decides the index of refraction of that type.
If the index of refraction of any medium is high, then it will refract most of the incident light and so the light' speed travelling through the medium will get slower.
So increase in refractive index decrease the light' speed. Thus, if the light' speed decreases or slows down significantly then the substance has high index of refraction.
