Answer :Erwin Chargaff a Biochemist
Explanation:
He formulated the base paring of double helix of DNA. He reasoned that since the percentage of four DNA bases are of this proportions in human;
Adenine=30.9% and Thymine =29.4%;
Guanine=19.9% and Cytosine =19.8%
Then, the amount of adenine will always be equal to thymine,
And the amount of Guanine equals to cytosine based on this percentages of distribution.
(Adenine and Guanine are large, molecule of Purines, while thymine and Cytosine are Pyrimidine)
He concluded (although scientist believed, he did not explicitly stated this) that this should be the base paring patterns in DNA molecule. This is the first Chargaff Rule.
His second rule is that the DNA composition, in the relative amount of the four bases Adenine, Thymine, Cytosine and Guanine varies in proportion from one organisms to another. And this is the basis of molecular diversity.
Answer:
They used to extract iron ore from this site.
Explanation:
First of this should probably be under physics and not biology... nevertheless for your question. Newton's first law basically says that an object in motion will stay in motion unless acted upon by another force. Initially, you are traveling at the same velocity as your car, however if the car suddenly stops and you are not wearing a seat belt you will continue to move forward at the same velocity until you smack against the steering wheel or dashboard. A seatbelt basically connects you to the car so when the car suddenly stops you stop by hitting into the seatbelt which would prevent the injuries of hitting the dashboard or breaking and flying through the windshield.
