It is false, every country has their own unique way of using agricultural practices.
Answer:
Oxygen is essential to enabling many of the Earths life forms to survive -- without access to oxygen, humans cant live for more than a few minutes. The air that enters human lungs contains about 21 percent oxygen. The process responsible for producing most of the Earths oxygen is known as photosynthesis. In this process, plants and certain other organisms convert sunlight into oxygen and other products.
Explanation:
Artificial selection is the breeding of the best species by humans. For example, the fastest horse or something like that. This means breeding with species with the traits that produce offspring with the desired traits. To do this variation is needed. Not all species are going to have the desired traits but not all are going to have the undesired traits. However, if there is no variation, all animals of the same species are either going to have the unwanted traits or the desired traits. Now, if they all have the traits that us, humans, don't want, then such a concept and process like artificial selection would not exist.
Passive Transport in Cells: Simple and Facilitated Diffusion & Osmosis. A cell membrane is selectively permeable - not permeable to everything. In this lesson, we'll talk about methods of passive transport along a concentration gradient, including simple and facilitated diffusion and <span>osmosis.</span>
