Genetic and biochemical analyses have shown that chimps are more closely related to humans than they are to orangutans.
a. true
b. false

b.True

Explanation:

Yes it is true that chimps are closely related to human.

Chimps ,bonobos and gorillas have same genetic and biochemical function like humans.That is why they are also called human ancestor.Some of chimps could able to transfer their body according to the environment and slowly slowly become human,but some of them could not able to transfer their body and they are still chimps.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
