Answer:
Dust bowl resulted from extreme drying and loosening of the soil that resulted in soil erosion by wind. Thus, it can be related that poor agricultural practices like over plowing , over grazing and leaving the land barren are human activities that must have contributed to the dust bowl.
Explanation:
- Dust bowl is referred to a period in early twentieth century when the the American and Canadian prairies faced severe dust storms.
- These dust storms resulted from severe drought and failure of practices to prevent soil erosion.
- Several people and livestock died as a result of choking.
- Over plowing, removal of top soil and small grasses exposed the soil to eroding winds and caused the dust storms.
Answer:
There are plenty of animals that live in wetlands, such as lizards, turtles, snakes, newts, Alligators, Invertebrates, and along with sea life. Scientists need to consider taking farmland and constructing it into a wetland; they would need to consider the influx and the outflow of the groundwater levels and the duration of ground saturation. Wetlands can have both positive and negative effects on humans. Some negative side to wetlands is how to release of chemicals coming from swamps could affect the environment for people. Also, how fast pollution could arise from these released chemicals. Waterlands could also change the water quality, quantity, and flow. Although there are negative points, we do have positive ones as well; This includes how the wetlands will be protecting endangered species and how it will clean the lakes and seas. The water quality, quantity, and flow also could increase instead of decrease. If I was to make a wetland regeneration project, I would monitor its success by making charts on what increased positively like the native plants and the nest platforms.

Answer:
THE DIAPHRAGM
Explanation:
The diaphragm is present beneath the stage and above the condenser in a microscope. It is that rotating disk that can be seen just underneath the stage. The function of the diaphragm is to control the amount of light once the specimen or slide is placed on the microscope.
The diaphragm consists of holes of different sizes. These holes majorly function in varying the amount and intensity of light on the slide or specimen.
