How might the conditions that caused the 1930s dust bowl disaster have been avoided

Answers

 It was mostly prevented by planting trees.

To prevent a disaster like the 1930s Dust Bowl, sustainable farming practices, better water resource management, and cultivation of drought-resistant crops and methods were required.

The Dust Bowl was an ecological catastrophe that struck the Southern Great Plains between 1933 and 1939. Prevention of such a disaster would have involved several key actions. First, farmers needed to apply more sustainable agricultural practices, such as crop rotation, contour plowing, and maintaining natural vegetation to prevent soil erosion. Heavy reliance on plowing and failure to use these soil conservation techniques led to the exposure of prairie soil, which, compounded by drought, turned fertile land into dust.

Secondly, a more careful management of water resources was necessary. The over-pumping of water from underground aquifers for irrigation led to the failure of grain crops, leaving the soil dry and vulnerable. Lastly, to avoid another disaster of this magnitude, it is essential to develop drought-resistant crops and farming methods suitable for the local climate, which doesn't naturally support non-native grain crops without supplemental irrigation.

Joe's boss allows him to leave early while others must stay to clean the store because he offers customers excellent service during his shift. This is an example of which of the following?

Positive reinforcement

Negative reinforcement

Punishment

Classical conditioning

Answers

Answer:

Positive reinforcement.

Explanation:

Positive reinforcement is a method in psychology, that refers to the introduction of a desirable or pleasant stimulus after the behavior.

Desirable stimulus reinforces the behavior, which makes it more likely that the behavior will reoccur in the future.

In this case, Joe's boss allowed him to leave early because he did a good job that day, so he got to finish his shift early and enjoy his free time. His boss is hoping that he will continue to do good work due to his generous act.

Answer:

Negative reinforcement.

Explanation:

Negative reinforcement is used in behavioural psychology. The term was used by Skinner, the father of operant conditioning. Through this theory, Skinner said that we respond to daily stimulus and our behaviour is a result of that situations.

In addition, Skinner used technical terms like negative and positive reinforcements. He defined negative reinforcement as a reinforced behaviour by avoiding a negative stimulus or situation, knowing negatives situations as those that make people uncomfortable.

Therefore, Joe avoided a negative situation, an uncomfortable outcome, because he could leave early; not being able to leave is a negative outcome for him. That's why this is an example of negative reinforcement.

Two minerals mentioned in this section which are stored in the bones are:

Magnesium
Calcium
Potassium
Phosphorus

Answers

Two minerals mentioned in this section which are stored in the bones are:

- Calcium

- Phosphorus

Calcium and phosphorus are the two minerals stored in the bones, both vital for bone structure and strength. While magnesium is also present in bones, potassium is not stored in bones but is important for muscle and nerve function.

The two minerals mentioned that are stored in the bones are calcium and phosphorus. These minerals are essentially involved in the structure and hardening of the bones. Calcium is the most abundant mineral in the body, with about 99% of it found in the skeleton. Phosphorus works closely with calcium and is stored in the bones, where the two minerals together form hydroxyapatite crystals, which provide bones with their rigidity and strength. Besides their structural roles, these minerals also participate in various physiological processes.

Magnesium is another mineral that is present in bone structure but in smaller quantities than calcium and phosphorus. Potassium, on the other hand, is mostly involved in muscle and nerve function and not stored in the bones. Knowing which minerals are stored in the bone is critical for understanding bone health and the prevention of bone-related diseases such as osteoporosis.
