The correct answer is b: cattle on rangeland. A point source of pollution occurs from a single identifiable and usually spatially narrow source. These sources of pollution are usually relatively easily to quantify and manage. In contrast, a non-point source of pollution, such as cattle on rangeland or irrigated agriculture, is variable on both spatial and temporal scales. These sources of pollution are difficult to quantify and manage.
Answer:
b. Pollen tubes did not enter all of the ovules in such pods
Explanation:
Quite sometimes, ovules fail to mature seeds because most of their flowers do not receive enough pollen to fertilize all of their ovules and are eventually aborted, thereby resulting in some ovules becoming mature seeds and others do not get matured.
Heredity increases diversity because when we inherit traits from our parents, we become a mix of both. Then, when we have children, they will inherit some of our traits and some of the other parent's traits. That increases diversity because different people get mixed together and create a new kind of person.
Answer:
They could have an overproduction of their offspring then being able to survive, and they will need to find different food. Two different species cannot live together its needed to be the same species.
