The correct answer is B. Protection and dispersal of seeds
Explanation:
In plants, fruits are structures that form as a result of fertilization, which makes ovules become seeds and flowers maturate to become fruits. This is necessary for the reproduction of plants, as fruits contain seeds or genetical material that is protected by different layers and leads to new plants if seeds are dispersed. The process of dispersal commonly occurs as the fruit falls from the plant or is eaten by other organisms and then disperse in other areas, which allow plants to reproduce. According to this, the main function of fruits is protection and dispersal of seeds.
Answer:
Atmosphere and geosphere is the part of the earth which is utilized in the nitrogen cycle.
Explanation:
In nitrogen cycle, the nitrogen which is present in the atmosphere comes down to the earth surface through rainfall. This nitrogen is absorbed by the earth and taken by roots of plants. Some amount of nitrogen is taken by many bacteria such as denitrifying bacteria which converts the soil nitrogen into atmospheric nitrogen and the nitrogen goes again to the atmosphere.
Answer:
because the more alike species are The more they have to adapt to try and compete with one another So the more different a species is the less they have to compete
According to the image, the fish underwent sympatric speciation. The new species of fish had mating seasons that were different from that of the original fish. Because of the differences in mating seasons, the fish underwent reproductive isolation. This mode of isolation would be temporal.
Sympatric speciation happens within a population of an organism that gets isolated reproductively due to differences in their mating periods. This time dependent isolation is called temporal isolation. Example, a fish population can split into two if some of the fishes start mating early in the spring while the rest mate late in the autumn. The spring-mating population will not become compatible to mate with the late-autumn-mating population.
