d. mesosphere

Stratosphere is the layer of atmosphere that is different because it doesn't have mixture of gases, it has layers of single gases.

Explanation:

The layer of atmosphere present above the Troposphere is called Stratosphere.  Hence, it is the second layer of the atmosphere.

Stratosphere is also the layer where ozone is formed. The higher layers of the stratosphere are higher where the lower layers, closer to the earth are cooler. The higher layers are warmer due to the absorption of ultraviolet radiation from the sun.

Above the Stratosphere is the Mesosphere. Above Mesosphere, the atmosphere forms the Thermosphere and finally, above thermosphere is the exosphere.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
