Captive-bred trout reduce the fitness of wild populations.1.00.80.6-0.40.2Relative fitness0WildCaptiveCaptive×WildWildCaptiveWhat can be said about the fitness of wild steelhead trout populations and captive-bred steelhead trout? (see figure above)The gene flow between hatchery-reared and wild populations is leading to a decline in fitness of wild populations.This data does not help us understand effects of gene flow on fitness.The gene flow between hatchery-reared and wild populations is neither helping nor hindering the fitness of the wild population.The gene flow between hatchery-reared and wild populations is increasing the fitness of the wild populations.

Option a): The gene flow between hatchery-reared and wild populations is leading to a decline in…

Answered: Captive-bred trout reduce the fitness…

(a) About how many microorganisms are found in the human intestinal tract? (A typical bacterial length scale is one micron = 106 m. Estimate the intestinal volume and assume bacteria occupy one hundredth of it.) (b) Discuss your answer to part (a). Are these bacteria beneficial, dangerous, or neutral? What functions could they serve?
Bacteria and other prokaryotes are found deep underground, in water, and in the air. One micron (106 m) is a typical length scale associated with these microbes. (a) Estimate the total number of bacteria and other prokaryotes on the Earth. (b) Estimate the total mass of all such microbes.
What is your favorite home-cooked meal? In terms of the three types of energy transport, how w it cooked?
(a) What is the order of magnitude of the number of micro organisms in the human intestinal tract? A typical bacterial length scale is 106 m. Estimate the intestinal volume and assume 1% of it is occupied by bacteria. (b) Does the number of bacteria suggest whether the bacteria are beneficial, dangerous, or neutral for the human body? What functions could they serve?
Angioplasty is a technique in which arteries partially blocked with plaque are dilated to increase blood flow. By what factor must the radius of an artery be increased in order to increase blood flow by a factor of 10?

When a person feels that he is about to fall, he will often put out his hand to try to break the fall. Explain why this natural reaction usually leads to bruises or minor broken bones such as in the wrists instead of major broken bones such as the skull.

A major artery with a cross-sectional area of 1.00 cm2 branches into 18 smaller arteries, each with an average cross-sectional area of 0.400 cm2. By what factor is the average velocity of the blood reduced when it passes into these branches?
Discuss the relative effectiveness of dieting and exercise in losing weight, noting that most athletic activities consume food energy at a rate of 400 to 500 W, while a single cup of yogurt can contain 1360 kJ (325 kcal). Specifically, is it likely that exercise alone will be sufficient to lose weight? You may wish to consider that regular exercise may increase the metabolic rate, whereas protracted dieting may reduce it.
