The air that is inside a ship is much less dense than water. That's what keeps it floating! ... As a ship is set in water, it pushes down and displaces an amount of water equal to its weight
The correct answer is: "Chimpanzees and modern humans shared a common ancestor."
The chimpanzees are not the ancestors of modern humans as because humans did not come from chimpanzees but from a common
<em>Hominin </em>ancestor. Neanderthals on the other hand, are also not ancestors of the humans but also shared a common ancestor albeit an earlier one compared to the chimpanzee. Most ancestors of humans originated in Africa, not in Europe.
Attached is a phylogenetic tree involving the evolution of humans and other primates from a common ancestor.
Answer: <u>Guanine
</u>
According to Chargaff's rule, the base pairing in the DNA and RNA is fixed. Adenine always pairs with Thymine in DNA and Uracil in RNA. Guanine pairs up with cytosine. This complementary base pairing is universal and constant. That's why amounts are also equal. It means if cytosine is 20% in any DNA sample, then amount of guanine would be 20% as well.

Scientific laws explain phenomena that have been proven to be true by the scientific community. In general, theories explain how a phenomenon occurs, whereas laws predict what will happen in a particular scenario based on an equation.
A scientific law foretells the outcomes of particular initial circumstances. It may tell you what color hair your unborn child would have or how far a baseball will travel when launched at a specific angle. In contrast, a theory seeks to offer the most plausible justification for why events take place the way they do.
The five most well-known scientific laws are:
- Bernoulli's law of fluid dynamics.
- Dalton's law of partial pressures.
- Hooke's law of elasticity.
- Fourier's law of heat conduction.
- Archimedes' Principle of Buoyancy.
