How is mass wasting different from other forms of erosion?
Romashka-Z-Leto [24]

Answer:

A

Explanation:

Examples of mass wasting are slides, falls, creeps, and flows.  Mass wasting processes are easily observable because they happen fast and suddenly and the changes are vividly evident in very short bit of time.   However, other methods of erosion such as mechanical and physical weathering occur very slowly and it would take many years for the changes associated wth their proceses to be vivid to the naked eye.

How does the cell recognize that lactose needs to be metabolized?
erastova [34]
Lactose metabolism is regulated by lac operon in prokaryotic cells. When in the environment lactose is present, the cell signals the presence of lactose and synthesizes the enzyme required for the degradation of lactose. Removal of lactose from the environment leads to the termination of the enzyme synthesis. Thus, the metabolism of lactose is environment dependent.

The metabolism of lactose is also dependent on the presence of glucose. Glucose is the favorite food for bacteria. If glucose and lactose both are present in the environment, the bacterial cells prefer glucose over lactose and lactose is not metabolized. In the absence of glucose, the cells will metabolize lactose.

What is a way to prevent eutrophication?
Anon25 [30]

Answer:

Agricultural fertilizers are one of the main human causes of eutrophication. Fertilizers, used in farming to make soil more fertile, contain nitrogen and phosphorus. The use, or overuse, of fertilizers can cause these nutrients to runoff of the farmer's field and enter waterways. Eutrophication can have serious effects, like algal blooms that block light from getting into the water and harm the plants and animals that need it. If there's enough overgrowth of algae, it can prevent oxygen from getting into the water, making it hypoxic and creating a dead zone where no organisms can survive.

The following is a list of methods that can be used to control eutrophication:

planting vegetation along streambeds to slow erosion and absorb nutrients.

controlling application amount and timing of fertilizer.

controlling runoff from feedlots.

The best, easiest, and most efficient way to prevent eutrophication is by preventing excess nutrients from reaching water bodies. This can be done in a number of ways, the simplest of which is just being aware of the chemicals and fertilizers that we are using.
