Answer:
ATP ???
Explanation:
atp molecules store and transfer energy
My answer -
<span>There are typically two
planets that are dubbed as Earth's twin. The first one, Venus, is called
Earth's twin because of its similar size, and how it is the closest
planet to Earth. But, scientists discovered that Venus's atmosphere and
temperature were totally different from Earth's. The other planet also
called Earth's twin is Mars. Mars is believed to have a large ocean on
the past. Some even say that life may have developed on Mars for a short
period of time. Furthermore, Mars has an average temperature of -70
degrees Fahrenheit, closest to Earth than any other planet. It seems that
water and life define the Earth, and if Mars has these characteristics,
it would truly be Earth's twin.
P.S
Have an AWESOME!! day :)

The answer is B because men only have one X chromosome. Their chromosomes are xy.
<span>The answer is molecular clocks.
Molecular clocks use rates of mutation to measure evolutionary time. This technique is based on the fact that 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 and vice versa.</span>
