The nitrogen cycle is impacted by humanswhenever fertilizer is applied to farmland to help crops grow. This adds nitrates to the soil. If soil erodes, the nitrates are transported and deposited in the nearest body of water. This can cause algae to overgrow in a process called eutrophication. The lake will run out of oxygen as the algae die off and bacteria begin their decomposition.Sessile organisms are greatly affected.
Answer:
Nitrate
Nitrate is the form of nitrogen most used by plants for growth and development. Nitrate is the form that can most easily be lost to groundwater. Ammonium taken in by plants is used directly in proteins. This form is not lost as easily from the soil.
Explanation:
The hypothalamus sends signals to the pituary glands. The hypothalamus releases dopamine, so I think dopamine is a good answer?
The reason is to help in seed dispersal. Seed dispersal is the movement or transport of seeds away from the parent plant. Due to the fact that plants have very limited mobility they have to rely upon variety of dispersal; vectors to transport their seeds, including both abiotic and biotic factors. Seed dispersal is important because if seed are not dispersed, many germinating seedlings will grow very close to the parent plant which would result to competition between every one of the seedlings as well as the parent. The competition for essential growth factors such as light, space, water and nutrients.
Explanation:
C. They make it more fluid
Lipids are composed of fatty acids which form the hydrophilic head and glycerol which forms the hydrophilic tail; their arrangement can give these non-polar macromolecules hydrophilic and hydrophobic properties. Via diffusion, small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds.
The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water to diffuse across the membrane along the concentration gradient.
Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers. Cholesterol, which is comparatively rigid, anchors other molecules attached to the membrane, maintain membrane stability or structural integrity and aid in separating some lipids, helping with membrane fluidity at low environmental temperatures.
