What would happen to temperatures on earth the suns heat were distributed throughout the atmosphere

Answers

If the sun's heat is distributed uniformly throughout the atmosphere, this will ensure that each point on the earth gets a moderate level of heat and temperature in these locations will be within the acceptable level.
If the sun's heat is concentrated in one part of the atmosphere, the location that correspond to the point of concentration will receive enormous amount of heat from the sun, which will shoot up the temperature of that location. This will leads to all manner of disruptions in the ecosystem that is found in that location.

For example, California's water cycle was on hold because we did not have any rain. The weather has been dry warm, so all of the water is being evaporated, but never reaching the precipitation phase of the cycle.

What are the Respiration effects on the pH?

Answers

Our blood have a pH around the 7.0, when we hold the breath our cells still breathing, and the release $CO_2$ , this compound react with water (hydrolysis).

$H_2O+CO_2\leftrightharpoons H_2CO_3$

This compound formed by this reaction is acid, carbonic acid.

Them the pH will get lower them normal, and our buld send an action to our body, and this reaction will be the breathing.

The concentration of a solution can be expressed in(I ) milliliters per minute
(2) parts per million
(3) grams per Kelvin
(4) joules per gram

Answers

Answer:

(2) parts per million

Explanation:

Concentration of a solution can be expressed in terms of parts-per-million (ppm).

ppm is usually used in the context of measuring very small concentrations particularly the amount of contaminants. It represents 1 part of the contaminant in 100000 parts of the total.

It is expressed as:

1 ppm = 1 mg / L

1 ppm = 1 mg/ Kg

(I ) milliliters per minute
(2) parts per million
(3) grams per Kelvin
(4) joules per gram
