Which of the following examples can cause gene flow between populations? an increase in predators to a population of zebra a volcanic eruption that kills half of a population of mice bird droppings that contain seeds from a different location a person that sprays a toxin on a group of mosquitoes

The right option is; bird droppings that contain seeds from a different location

Gene flow is the introduction or transfer of genetic variation from one population of a species to another, thereby influencing the general makeup of the gene pool (the population’s total genetic material) of the affected population. Bird droppings that contain seeds from a different location can cause gene flow between populations because the seeds in the bird droppings will introduce genetic material to another population of species hence, causing gene flow.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction

example: humans, seeweed, cattles, etc.
