An additional difference is that humans have much greater fine motor control. Current hypotheses describing these differences are that chimpanzees have fewer motor units for a given number of muscle fibers and human central nervous systems put a limit on the number of motor units that may be stimulated at one time. Explain these physiological differences between humans and chimpanzees using the hypotheses mentioned above. There are 3 types of muscle fibers: fast-twitch TypeI A oxidative (Red), fast-twitch Type II B glycolytic (white), and slow-twitch Type I (Red). Based on the hypotheses mentioned above, most likely chimpanzees have more Type II B fast-twitch glycolytic fibers than fast- twitch type II A and slow twitch type I fibers, and humans have more Type 1 slow-twitch muscle fibers. These 3 types of fibers have different mechanical and metabolic characteristics. For instance, Type 1 (slow twitch- red) muscle fibers have greater quantities of mitochondria, blood vessels, and oxygen bound myoglobin proteins. As a result, they have a greater access to larger amounts of oxygen. Type Ifibers undergo acrobic respiration and produce a great a lot of energy process of producing energy is a multi-step process that takes a while. Because of this, their contraction speed and conduction velocity (receiving of nerve signaling) is slow. These fibens and are fatigue resistance. As well, they have long duration contractions and are great for long term aerobic activities. In sum, these muscle fibers are great for fine motor movement. We in fine motor movement activities like flipping pages in a book or typing and engage in lesser gross fine movements compared to chimpanzees. On the other hand, Type II B fast-twitch glycolytic (white) fibers don't have a lot of J English (US)

Explanation / Answer

1) Inulin clearance is used as a measure of glomerular filteration rate. Here, the value of insulin clearance is 300 mmol/l and the clearance of substance Q is 1440 mmol/l. The clearance of substance Q is greater than that of insulin. Therefore, the substance Q must have been cleared from the body by both glomerular filteration and tubular secretion.
