Some impacts/after-effects include tidal flooding, habitat destruction, extreme weather, pest propagation, and heat waves
This invention was a commercial failure. Edison resolved that in the future he would only invent things that he was certain the public would want. ... This gave Edison the money he needed to set up his first small laboratory and manufacturing facility in Newark, New Jersey in 1871.

Answer- B. Neuron
Hope this helps :)
Answer:
The letter B is the right answer.
Explanation:
The main objective of the hardin and Weinberg equilibrium is to determine how the allelic frequencies change within a population.
In 1908, Godfrey H. Hardy (1877-1947) and the German physician, Wilhem Weinberg, proposed that if no evolutionary factors act on a given population, the frequencies of their alleles would remain unchanged for several generations. This proposal became known as Hardy-Weinberg's Law (or theorem) or principle of gene balance.
According to this law, the necessary conditions for a population to reach equilibrium are:
a) The population must be large, so that all possible intersections occur.
b) The population must be panmatic (from the Greek pan, all, and from the Latin miscere, mix), that is, the crossings must be carried out randomly, without preconditions.
Within these conditions, without mutation, migration or selection, there will be a genetic balance. Over the generations, genes will not change.
Answer:
The innermost layer of the atmosphere is TROPOSPHERE.
Explanation:
Atmosphere - The gaseous surroundings of earth is known as atmosphere. On the basis of variations in temperature, atmosphere has several layers as follows-
<u><em>Troposphere</em></u>- <em><u>It is the innermost layer of the earth. extending 17 km above sea level at the equator and about 7 km above the earth's poles</u></em>.Weather phenomenon occurs in this layer.It is known as troposphere because of vigorous air current.
<u><em>Stratosphere- </em></u>It is the second layer above troposphere.It extends approx 50 km above the earth surface.Ozone is also found in this layer. ozone plays very important role in maintaining thermal balance.
<u><em>Mesosphere-</em></u> It is the third layer of earth surface.Extending approx 50 to 85 km above the earth.Here temperature remains low.And at the top of this layer i.e, mesopause has the coldest temperature.
<u><em>Thermospher-</em></u> Temperature in this region is slightly high because of absorption of solar light.
<u><em>Exosphere-</em></u> It is the outer most layer of earth. Any particle or object in this layer if moving very fast can escape to the space. The <u>exopause</u> boundary of exosphere is approx 250-500 km above the surface. This is the transition layer between earth atmosphere and space
