Blood flows to the brain through the internal carotid and vertebral arteries and away from the brain through the internal jugular vein. The internal carotid artery supplies the brain, while the external carotid nourishes other portions of the head, such as the face, skull, scalp and the meninges. The vertebral arteries provide supply to the upper spinal cord, brainstem, cerebellum, and the posterior part of the brain.
Answer:
Charles Ehler: incorrect.
Wendell Mullison: correct.
Robert Rodriguez: correct.
Judy Johnson:correct.
Explanation:
-Charles Ehler´s statement is incorrect because in order for a chemical company launch a new product it must pass several tests, that´s why products lasts years in proves, there are several tests such as the environment test that proves that the product doesn´t affect other species, or the human safety that makes sure the product doesn´t affect human health.Wendell Mulison´s statement proves to be correct with this as well.
-Robert Rodriguez´s statement is correct because even though there are several tests that take care human healt there are just a few based on the damage pesticides produce to the land where are used.
-Judy Johnson´s statement is correct because science has proved that the resistant of parasites as being increasing with the products tat are used to combat them. Bacterias are an example of it, many drugs used against bacterias are now useless for some people because of the resistantthey have developed.
-One specie that can be taken as a pesticide can be the ground snail, that affects some plants and also may contain a parasite aclled "Hepatic fasciola" that affects sheeps and goats of farmers.
-One viable method to control pesticides is the sue of other species to control them, this specie has to be adequate to the land, for example, if a farmer wants to get rid of the ground snails because of the parasite and the damage they do to their platings, they can introduce ducks to the farm that eat them without damaging the land with any kind of chemical product.
Answer:
Population
Explanation:
Population is a group of individuals that live in the same geographical area which have the ability to interbreed because they belong to the same species. So organisms of the same species when live in a particular area are considered in population but members of the same species that are geographically isolated and can not interbreed do not make a population.
Many population comes together to form community and many communities together forms an ecosystem. An ecosystem is a functional unit which is made up of many communities with interacts with its physical environment. So the correct answer is population.
