Molecular clocks use rates of mutation to measure evolutionary time.Mutations add up at a fairly constant rate in the DNA of species that evolved from a common ancestor. The more mutations that happened in each lineage, the greater is the differences between these lineages.
Answer:w
when a gas is compressed, its' volume decreases.
Explanation:
When a gas is compressed, its volume usually decreases which also causes an increase in temperature. The pressure in addition increases which causes and increase of gas molecules. The molecules collide more frequently which is the reason why temperature will increase.
Summer
, for the northern hemisphere, summer is the warmest time of year. It's not because the planet is that much closer to the Sun, it's because the top part of the Earth is facing the Sun for a amount of time.
The Sun is directly over the Equator during the autumnal equinox, and heating the northern and southern hemispheres equally. As the northern hemisphere is moving towards shorter days and the cold winter, the southern hemisphere is watching the snows melt and the flowers bloom during their spring.
Summer is the season where the Earth is tilted way from the Sun and the South Pole is getting all of the light
Spring is a bit of a mirror image to our position in autumn. The Sun is directly over the Equator during the equinox and the northern and southern hemispheres
