Not really sure about the human part but I know that most captive born predators die if they are released most likely because they have no wildlife instincts
Explanation:
If lions attack the slowest animal in a herd, it is beneficial to the herd in the following ways:
1.) Evolutionarily, the faster herd members survive and breed, increasing the speed of the offspring and guaranteeing better survival for the future population.
2.) The lions focus on the straggling animal, allowing the rest of the herd to escape.
3.) The death of one herd member ensures the survival of many more.
The independent variable of an experiment is the one that is intentionally changed or manipulated to see the results of changing said variable.
We are told that in each different group, the amount of caffeine that is given to the dogs changes - in the control group, they get no caffeine, in the 2nd group, they get 10 mg of caffeine each, and in the 3rd group, they get 50 mg of caffeine each.
Therefore, since the amount of caffeine that is given to the dogs is the only variable that is being manipulated, this is the independent variable.
Answer:
Kettlewell thought that if natural selection caused the change in the moth population, the following must be true: Heavily polluted forests will have mostly dark peppered moths. Clean forests will have mostly light peppered moths. Dark moths resting on light trees are more likely than light moths to be eaten by birds.
