Only the strongest live on to pass on their genes. the weak die
The answer is (3) an increase in the proportion of offspring <span>that have favorable characteristics.
</span>In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited. Peppered moth color variation is a good example of natural selection.<span>During the Industrial revolution, due to pollution, trees become darker in the urban area. Light-colored moths were, thus, easy prey. The dark-colored moths were able to camouflage on dark trees and avoid predators. The phenomenon is known as industrial melanism. So, in polluted urban areas, the number of dark-colored peppered moths increased. In the clean environment, were much effective in hiding from predators and they outnumbered the dark-colored moths.
Therefore, the </span>proportion of offspring <span>that have favorable characteristics in such environment will increase.</span>
The nervous system is responsible for voluntary/involuntary movement. The glands of the endocrine system produce hormones that are responsible for growth, metabolism, sexual function, etc.
Answer:
The life cycle of a goldfish starts out as an egg. The female fish will lay about 25 eggs, but unfortunately only some grow up. The eggs usually hatch within 5 days and if you have a fish tank then you should take the adult fish out or else it may eat the eggs. After the egg hatches, it turns into a fry,(this is what a baby goldfish is called) Once they hatch, they will stay attached to the plants for two days, after that, you should start to feed them. Once they are not fry anymore, they turn into adult goldfish. If you take care of them properly, they could last up to 15 years! Once the fish are complete adults, they can lay eggs. The females rub up against plants and lays eggs while the male Goldfish sprays the eggs to make them fertilize and turn into fry.
