Answer:

The correct answer is mesosphere.

Explanation:

The atmosphere exhibits five distinct layers, which are determined by the modifications in temperature that take place with the upsurging altitude. These are troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Of the mentioned layers, the mesosphere, that is, the layer present above the stratosphere is considered as the coldest layer of the atmosphere. The coldest portions of the atmosphere are situated in this layer and can reach up to -90 degree Celsius.

Potential Energy on the way up the rollercoaster
Nana76 [90]

Answer: Because The potential energy you build going up the hill can be released as kinetic energy — the energy of motion that takes you down the hill. Once you start cruising down that first hill, gravity takes over and all the built-up potential energy changes to kinetic energy. Gravity applies a constant downward force on the cars.Potential energy is the energy an object has as a result of its position. Potential energy is stored energy that has not yet been released. Gravitational potential energy is potential energy that results from an object's position in a gravitational field, and is equal to the object's weight multiplied by its height.

hope this helps have a nice day❤️

Allen and andrew both have the same biological parents. Why do they not resemble either of there parents
taurus [48]
This can be because of their genetics. The siblings may not have inherited their parents looks, but maybe they inherited their grandparents looks, or even their aunts looks. This is all due to genetics. It's sort of the same thing, when two caucasian parents have an african-american child. That would be because somewhere along the family tree someone was african-american. 
Anyways, I hope this helps!

Answer:

Explanation:

All living organisms such as fish,plants and animals  need water to survive and also the require certain pH level of water in order to be healthy.Its a acid and base balance reaction.Strong acids dissolve into water and its changes water's pH.if water's pH level drops it becomes acidic suppose a fish waste ammonia releases and dissolves in water to form harmless ammonia ions,carbon dioxide ions and hydrogen ions even some limestone also rises pH level and water becomes more basic.To make the tank water alkaline, add some corals and aerate the tank water by fixing an air pump so that excess of carbon dioxide eliminate out and water pH level comes to neutral this is the reason water becomes slightly alkaline and the fishes are able to reproduce.
