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:
a. No, because Acetyl CoA goes into the TCA cycle, which will not occur in cells without oxygen.
Explanation:
Fatty acids in the body gets converted to acetyl-CoA by the process of β-oxidation. After the conversion of fatty acids to acetyl-CoA , acetyl-CoA undergoes the TCA cycle which produces NADH and FADH₂ which further undergoes electron transport chain where oxygen gas acts as the final receptor for these molecules and high energy molecules known as ATP are released in the process.
<u>Thus, in the absence of oxygen, TCA will not occur and thus no energy is provided to the body.</u>
