<span>The evidence that led to this classification was the different sequences in ribosomal RNA in the different organisms. That factual information led to scientists figuring about how long ago different organisms shared the same ancestor.</span>
Hope this helps :)
Answer: D) A car with the windows rolled up gets very hot on a summer day.
A radiation can be defined as the transmission of energy in the form of waves, particles or rays through space or through a material medium. A radiation is being transmitted from one source till it reaches it's destination. A radiation transfers heat energy. A car with the windows rolled up gets very hot on a summer day would be evidence that heat was transferred by radiation because the glass pane of the window of the car being transparent will absorb the heat energy coming from the solar radiation.
The number of molecules in some water isn't affected by changing its temperature. But to know if you have the same number of molecules in two water samples, you need to compare their masses, not their volumes. When you heat some cool water, it expands. (When you slightly warm some ice-cold water, it contracts a little, but let's keep this simple.) So hot water takes up more space than cold water. The amount of space something takes up is called volume. If you were to have 2 cups of water, one of hot water and one of cold water with equal volumes, the cold water would have more molecules.
<span>Hot and cold water are made of the same type of molecules. Each molecule has one oxygen and two hydrogen atoms. The difference between them is the speed of the molecules jiggling around. </span>
