ILL GIVE BRAINLIEST HELP ASAP A watershed, also known as a drainage basin, is an area of land where the water drains to a central point like a lake, river, or an ocean. Natural vegetation in the landscape, helps maintain the natural flow regime of water and rapid changes in water levels in lakes and wetlands. Imagine a portion of a wetland that has changed as seen in the image . Predict what will happen to the natural flow of water as natural vegetation is replaced by impervious surfaces.

Groundwater flow will increase to its end point causing flooding.

Runoff will increase and less water will penetrate the soil to become groundwater.

Ground water will puddle up and remain in one place instead of flowing to a central point.

Impervious surfaces such as roads and parking lots will divert water flow and it will not reach its end point.

Achemical reaction (also known as a chemical change) produces substances that are chemically different from the starting materials. an example of a chemical reaction is the formation of water from hydrogen and oxygen gas.in a physical change, a substance changes its physical appearance but not its chemical identity. an example of physical change is the formation of liquid water from solid water, a familiar process called melting. physically, liquid water looks very different from solid water (ice) but the chemical identity, water, is the same for both. which of following changes that affect the composition of our atmosphere involve physical changes and which involve chemical reactions? oxygen gas changes to ozone during thunderstorms carbon dioxide is produced by the combustion of gasoline in an automobile engine. when coal, oil, and natural gas are decomposed in landsills they produce methane gas. freezing rain develops when a warm air mass overrides a cold air mass. fog forms from water vapor when the temperature drops below the dew point

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

Chen drew a diagram to compare the ways in which different organisms obtain nitrogen. which label belongs to the area marked z?
