c this is the answer because if you go back to any other ones they dont make sense so :(
The theory of evolution can be proved by the comparison of DNA genetic sequences of organisms.
<u>Explanation:</u>
The evolution can be proved by following
- Homologous organs - they are organs that have similar basic structure but perform different functions. example: Human, Bird.
- Analogous organs-they are organs that perform same function but have different structure or basic design. example: Bird and insect.
- Fossils- the remains of dead animals and plants.
Dead organisms get decomposed by microbes, due to the absence of oxygen and moisture some body parts does not decompose.
The soft parts of body gets decomposed hard parts take time to decompose and get covered by sea, at these deep levels the decomposition stops and the hard parts remain preserved called fossils.
The answer is; T
The convection currents in the mantle are similar to those of water in a vessel being heated from below. As the mantle is heated by the core below, the hotter part of the magma begins to rise and the cooler mantle above begins to dive to replace the rising hotter mantle. It is these currents that cause the tectonic plate movements of the earth’s crust.
Well, A humans brain is bigger than a Sheeps brain, And a human has more Ridges and Contours also, Hope this helps
