Answer: B
Explanation:
In Active transport, an input of energy in the form of ATP is needed to transport substances against the concentration gradient, I. E it allow the movement of molecules from an area of low concentration to one of higher concentration. And hence it is called active transport because energy is required to drive this process.
Active transport is the opposite of passive transport, where molecules move from a region of higher concentration to a region of lower concentration without the input of ATP.
Answer:
Albert Einstein is a German-born physicist and scientist who has created many ideas and theories relating to the study of relative. He is famously known for creating the famous equation 
(Energy equals mass times the speed of light squared).
He was involved in the help of creating nuclear powered- mechanisms (not for destroying things, but for helpful, everyday things). Matter has an inherent amount of energy to it, mass can be converted (under the right conditions) to pure energy, and energy can be used to create massive objects that did not exist previously. Nuclear fission takes place when a heavy atomic nucleus, such as uranium, breaks into two or more smaller pieces with the release of some energy. During this process some of the mass of the original atom is converted into energy in accordance with the equation .
Fertilizer Runoff
The excess nutrients provided by the fertilizer allow for rapid growth of algae and microorganisms. This fertilizer runoff can come from agricultural lands, or from residential areas.
Predator/prey web relationship is found in all ecosystem. A rise in the snowy owl population would have what effect on the snow goose in that The snow goose population would rise due to lemming, and subsequently fox, populations declining.
- Food webs often has predator/prey relationships. They show the direct relationships in ecosystems such as the predator-prey relationships.
- Predators includes big cats such as cheetahs and lions. They often hunt prey in temperate grasslands.
In North America, predators such as wolves, coyotes and foxes mostly hunt for mice, rabbits and deer.
