The correct response is this: NATURAL SELECTION FAVORED THE EVOLUTION OF LARGER BRAINS, THIS SUGGESTS THAT THE BENEFITS OF LARGE BRAIN OUTWEIGHS THE COSTS.
In fossils record, the shift from Australopithecus to homo is characterized by larger body and brain sizes and all through subsequent evolution, brain size has to continue to get bigger. The possession of large brain make man to be much more advanced in thinking than all other animals.

Answer: False
Explanation:
Protozoans are not the organism that fix nitrogen for the plants. The organism that fix nitrogen to convert it into a form which can be used by plants are known as diazotrophs.
These are bacteria and archae that fix nitrogen gas found in the atmosphere into more usable form such as ammonia.
These organism can grow without any external source of fixed nitrogen. Example: Rhizobia and azospirillium.
Answer:
thermophile.
Explanation:
A thermophile is a kind of bacteria that belongs to the Archaea Domain and they are the kind of animals that can live in a region of high or extreme temperature. There has been a research on a kind of thermophile which is known as Methanopyrus kandleri which can exist in an extreme temperature of up to 500° C.
So, if we take a look at the question again we can see that after 48 hours and at 37°C 20,000 bacteria per milliliter are already in the tube and at more higher temperature of 55°C we have 1,568,000 bacteria per milliliter which means that at higher temperature more of the bacterial is produced.
C hope it helps you. Thanks and have a great day
