What 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.
The fur of polar bears consists of hollow fibers. (Sometimesalgae will grow in the hollow regions, giving the fur a green cast.)Explain why hollow hairs can be beneficial to the polar bears.

Both A & Carrow_forwardA Hippogriff is a magical beast that had the front legs, wings, and head of a giant eagle and the body, hind legs and tail of a horse. It is very similar to another magical creature, the Griffin, with the horse rear replacing the lion rear. A slightly different breed of Hippogriffs, living in the Rathlin Island—the northernmost point in Northern Ireland, was known to have a growth rate of 0.2 individuals per individual—year. From an initial population of N0, it grew to 35 individuals after 5 years. After 17 more years, the total population of hippogriffs in Rathlin Island rose to 1588 individuals. Solve for the carrying capacity of Rathlin Island and the initial population of the said specie.

Fat is a good form of energy storage because it provides the most energy per unit mass: 1.00 grams of fat provides about 9.40 (food) Calories, compared to 4.20 (food) Calories per 1.00 grams of carbohydrate. Remember that Calories associated with food, which are always capitalized, are not exactly the same as calories used in physics or chemistry, even though they have the same name. More specifically, one food Calorie is equal to 1000 calories of mechanical work or 4184 joules. Therefore, in this problem use the conversion factor 1 Cal = 4184 J.
