Why do you think during the evolutionary process there was a correlation between brain size increasing while cecum size decreased in the omnivores? How does insect respiration differ from that of vertebrate respiration? How do they manage to respire?

Brain size increase due to find out improved quality diets whereas cecum size decrease due to reduction of its need.

Explanation:

Brain size increased due to the need to increase the mental capacity of an organism in order to explore the environment for the survival such as search for improved quality diet and the cecum size decreased because omnivorous diet improved due to the reduction of its need as a component of the digestive system. Insects have different respiration system as compared to vertebrates because vertebrates uses lungs for respiration whereas the insects uses tracheal tubes for the absorption of oxygen and removal of carbondioxide gas.

this is math not biology xd

c: warm water flows from the western tropical pacific toward south america. that should be the right answer! hope it .
