Answer:
a. Comparative molecular studies trace our earliest genetic material to Africa
Explanation:
With the development of the genetics we have been able to come to new findings or confirm some suspicions when it comes to the origin of the humans. The genetic analyses of the human DNA and the other hominids that have died out, as well as out closest ''cousins'' in the animal kingdom, have shown that the earliest human ancestors have evolved in Africa. Over time, as the conditions allowed it, the hominids started to migrate out of Africa and gradually started to settle all around the planet.
Domain (Specifically domain Eukarya)
Answer:
Is this a question? I don't understand
Explanation:
The correct answer is - C) 667 x 10-13.
The constant that is used in the equation for gravity, or rather gravitational pull, is 0.0000000000667. This same number, in proper scientific notation goes in the shape of 667 x 10-13.
The reason for that is very simple. Any number multiplied with 10-13 will give the exact same number, but as the last part of 13 decimal number. The -13 part dictates the number of decimals. So in the case of 0.0000000000667, the last part 667 is the number that is multiplied, but because the multiplying is in minus, the number goes on the back of the number. Since it has three numbers in it, ten zeros are added in front of it, in order to get the 13 decimals.
