The answer is D. Exosphere
Exosphere is the outermost Layer of the Atmosphere that goes out about 500 - 10,000 Km in altitude.
It's the place where satellites and the space shuttle orbit the earth. Because it's difficult to define the boundary between exosphere and the outer space, exosphere may be considered as a part of outer space
Answer:
Drought is a condition, not a hypothesis. Drought is the lack of rain, or evaporation in excess of precipitation.
The CAUSE of drought is a multi-pronged hypothesis. It can be due to cyclic changes in ocean temperature (El Niño/La Niña). It can be due to rain shadow downwind of a mountain range. It can be due to fluctuations in the sun’s brightness. It can be the result of urban sprawl and resulting shifts in upwind evaporation/transpiration. It can be the result of climate bands shifting in response to changing atmospheric composition. It can be the result of agricultural practices upwind. It can be just bad luck, with a location consistently not being the whatever-percent chance of where it’s raining.
Answer:
Si y No
Explanation:
la contaminacion de los automoviles es definitivamente es mala, pero piensa el dia a dia de todas las personas de tu pais sin ningun automovil?. Las armas son muy malas, pero piensa que seria de la policia o el ejercito sin las armas para poder defender el pueblo? Los experimentos en Animales son muy malos, pero piensa que seria de las vacunas, todas las investigaciones y el conocimiento que hemos tenido gracias a la realizacion de experimentos en animales? digo, es malo, pero piensa lo indispensable que ha sido para que la humanidad la tenga mas facil?
Mainly because of the fact that in January the Earth is tilted away from the sun, reaulting in those cold winter nights. However, in July the earth is tilted more toward the sun resulting in those warm sunny days.
Solution :
a). Let x denotes ACT scores.
ACT scores = 
Mean, 
Sample variance, 
= 11
b). To test whether or not variance of ACT scores of population (say 
) of the UTC students is significantly more than 8.
Consider the hypothesis :
vs 
It is a right tailed test and α = 0.05
We have
So test statics is
= 8.25
Since our 
and it falls in a acceptation region, hence we fail to reject 
and conclude that variance is not greater than 8 significantly.
