Explain why the body switches to utilizing more carbohydrates during higher intensities of exercise.
Explain why males sustain anaerobic work for longer durations than females.
At higher intensity of exercise, the energy demand increases; the oxygen supply fell short of that required for sustaining aerobic respiration.anaerobic respiration yields lesser amount of energy per unit of carbohydrates used hence more amount of carbohydrates are required to produce an equivalent amount of energy.
Males can sustain longer duration of anaerobic work due to a greater disturbances of acid- base balance post exercise and due to the fact that they can tolerate higher amount of blood lactate concentration than females during the exercise.

Given that girls naturally gain substantially more body fat than boys during puberty, why would any culture create physical ideals that demand thinness in females once they reach puberty?
There are more cells than organelles in the human body. Briefly explain why it is false or reword it to make it true.
Dr. Fletcher is interested in understanding whether joining a fraternity/sorority causes people to become more concerned about their attractiveness and appearance. He recruits a group of 55 freshmen (25 males, 30 females) who are planning to go through fraternity/sorority recruitment on his campus. After they join, he gives them a measure of attractiveness concern/appearance concern (the Body Concern Scale, where higher scores indicate higher body concerns). Could you explain why Dr. Fletcher is conducting a quasi-experimental design rather than a...
Explain why the first 2-3 minutes of aerobic (steady-state) exercise feels more difficult than when you are in the middle of the exercise.
Explain why are women in old age more likely than men to live in poverty during the retirement years? Describe end-of-life issues that can arise and how they can be managed
Explain why thunderstorms are more likely in the summer than in the fall during rainstorms, after calculating the energy released under each condition. Assume a summer temperature of 90°F and fall 40°F and that the rain is 40°F. Note that the specific heat of water is 4.184 J/g-˚C, and that the heat of vaporization of water is 2600 J/g.

According to Robert Trivers, why are men generally larger and more physically aggressive than women? Because women are more reproductively “valuable” than men, hence competition for mates is fiercer among men Because men invest more heavily in reproduction than women Because men secrete more testosterone Trivers’ theory does not speculate on the origin of the sex difference in size and physical aggression Although some women are interested in casual sex (short-term mating), research has suggested that there are differences in...
