The following are key characteristics of ape skulls that human skulls do not have:
(1) Prognathic Jaws: A chimpanzee’s maxilla (upper jaw) and mandible (lower jaw) protrude significantly. Typically, the bone from the nose to the tip of upper teeth extrudes out at about a 45 degree angle, whereas a line drawn from the nose to the chin of a typical human is vertical or concave.
(2) Large Brow Ridges above the eye sockets. Humans have negligible brow ridges.
(3) Absent or small laid back forehead: Apes lack significant vertical foreheads. Humans have large vertical foreheads, which provide room for the much larger frontal lobeof our brains. This is an important difference, as the large frontal lobe of the human brain allows us the ability to make decisions and solve problems. It also controls our behaviors, voluntary movements, emotions, and consciousness. Without a forehead, an animal would not have room for a large frontal lobe, and could not perform functions that differentiate animals from humans. The ability to make tools, improve on them, and the ability to remember how to make them, wouldn’t be possible without a forehead and large frontal lobe.
(4) Small Ovoid or Flat Cranium that houses their much smaller brains. Human adult craniums are about two to three times the volume of ape craniums. Ape craniums are narrower than the lateral extents of the eye sockets, whilst human craniums are far wider then the outer extend of their eye sockets.
Breathing is usually controlled subconsciously by the respiratory center at the base of the brain. Breathing continues during sleep and usually even when a person is unconscious. People can also control their breathing when they wish, for example during speech, singing, or voluntary breath holding.

To find the average number of cell cultured per area, you have to divide the total cell count with the total area. The cultured cells contains 7 x 10^5 cells count in 50 ml of medium area. The number would be: 7 x 10^5 cells / 50ml= 0.14x 10^5 cells /ml= 1.4 x 10^4 cells/ml
Answer:
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.
Explanation:
Energy is passed between organisms through the food chain. Food chains start with producers. They are eaten by primary consumers which are in turn eaten by secondary consumers. They are then eaten by tertiary consumers and in a long food day these can be eaten by quaternary consumers
