1. Humans should worry about atmospheric changes as they can affect their health in the sense of their lungs and other important body organs being damaged.

2. Positive effect of humans on ozone layer:

The fact that humas have stopped using CFCs has helped the ozone layer as these had a bad effect on this layer protecting us.

Negative effect:

One thing causing a bad effect on the ozone layer is carbon dioxide and the fact that humans are using it very often it causes the ozone layer to decrease in size meaning that the ozone layer won't be capable to protect us from harmful gases.

4. Scientists think that we should try stop the amount of carbon dioxide from rising because the increase in carbon dioxide leads to the earth becoming warmer and this can lead to a drastic change in the climate.

If blood supply to an arm is cut off, the arm would become ischemic, which means that there would be no blood flow to the tissues in the arm, which could lead to tissue damage or death and after five minutes, the blood in the arm would have decreased oxygen levels, increased carbon dioxide levels, increased acidity, and decreased pH.

The correct option to the given question is option d.

If blood supply to an arm is cut off, the arm would become ischemic. The absence of blood supply means that the cells in the arm would not receive oxygen or nutrients, which are essential for cell function and survival.
After five minutes, if blood in the arm is sampled and analyzed, the following changes would be observed:
Decreased oxygen levels: Since blood is not flowing to the arm, oxygen levels in the blood would decrease. This would lead to hypoxia, which is the condition of not having enough oxygen to meet the body's needs.
Increased carbon dioxide levels: As oxygen levels decrease, carbon dioxide levels in the blood would increase. Carbon dioxide is a waste product of cellular metabolism, and it is normally carried away by the blood to be exhaled by the lungs. If blood flow is cut off to the arm, carbon dioxide would build up in the tissues.
Increased acidity: When cells are deprived of oxygen, they switch to anaerobic metabolism, which produces lactic acid. The accumulation of lactic acid in the tissues would lead to an increase in acidity.
Decreased pH: As a result of the increased acidity, the pH of the blood would decrease. pH is a measure of how acidic or alkaline a substance is. A lower pH indicates higher acidity.thus, correct option is d.

The correct option that represents an example of fungi playing an important role in maintaining ecosystem balance and health is a) Decomposing dead organic matter.

An ecosystem is a balanced, self-contained community of living beings and their environment, with an intricate web of relationships between living things and the environment that is influenced by biotic and abiotic factors. Fungi play an essential role in maintaining ecosystem balance and health, especially through the process of decomposing dead organic matter. Hence, option (a) is the correct answer.
Fungi are organisms that play a vital role in maintaining the balance and health of the ecosystem. They exist in a wide variety of forms and serve many important functions in the environment. Fungi are well-known decomposers that break down dead organic matter, which is important in nutrient cycling.

They break down dead plants and animals, releasing nutrients and carbon into the soil, and recycling them back into the ecosystem. This process ensures that the essential nutrients are available to other organisms in the ecosystem.

In addition, fungi play a crucial role in the formation of mycorrhizae, which are symbiotic relationships between fungi and plant roots. The fungal hyphae penetrate the roots of plants and extract nutrients such as nitrogen, phosphorus, and other minerals from the soil. This relationship benefits both the plant and the fungus.
Moreover, fungi are also used in the production of food and medicines and are important for the functioning of the earth's ecosystems. They are also involved in soil remediation, helping to break down toxins and pollutants in the soil.

Overall, fungi play an essential role in maintaining the balance and health of the ecosystem, and their role should be preserved to keep the earth's ecosystems healthy.

Rats that have a damaged amygdala will show no fear when placed next to a cat.

The amygdala is a part of the brain that plays a crucial role in processing emotions, particularly fear and anxiety. It is involved in evaluating potential threats in the environment and initiating fear responses. Studies have shown that damage to the amygdala can lead to a significant reduction or complete absence of fear responses.

In the specific scenario mentioned, rats with a damaged amygdala would not exhibit the typical fear response when placed next to a cat, despite the cat being a natural predator.

This is because the amygdala is responsible for signaling danger and triggering fear-related behaviors, which would normally be evoked in the presence of a potential threat like a cat. Without an intact amygdala, the rats would not recognize the danger and thus display a lack of fear.

The type of contraction occurring as the elbow flexes is called the concentric contraction, while the type of contraction occurring as the elbow returns to its starting extended position is called the eccentric contraction.

The muscle responsible for the concentric contraction in the bicep curl is the biceps brachii muscle. On the other hand, the muscle responsible for the eccentric contraction is also the biceps brachii muscle.The easiest range to perform the bicep curl is at the mid-range because it provides the best mechanical advantage to lift the weight.

Furthermore, the mid-range allows the maximum amount of muscle fibers to contract at the same time. When the biceps curl is performed at the beginning or end range, there is less mechanical advantage, resulting in fewer muscle fibers contracting at the same time.

Based on the given information and analysis, options B and D are the correct statements about the city's consumption of surgical gowns during the pandemic. The new equilibrium quantity could be higher than the pre-pandemic level, and the new equilibrium price could be lower than the pre-pandemic level.

Option A: Government revenue will fall by $2,000.

This option is not entirely correct because we don't have enough information to determine the exact impact of the removal of tariffs on government revenue. However, we can assume that the removal of tariffs will reduce government revenue, but the exact amount depends on various factors such as the amount of tariffs collected before the pandemic, the current level of demand, and the extent of the tariff reduction.

Option B: The new equilibrium quantity will be 5,000 boxes.

This option could be correct because the removal of tariffs on imported medical supplies could lead to an increase in supply, resulting in a lower equilibrium price and a higher equilibrium quantity. Therefore, if the demand for surgical gowns in the hypothetical city increases due to the pandemic and the removal of tariffs leads to an increase in supply, the new equilibrium quantity could be higher than the pre-pandemic level.

Option C: The supply curve will shift to the left.

This option is not correct because the removal of tariffs on imported medical supplies would likely lead to an increase in supply, resulting in a shift to the right of the supply curve. Therefore, the statement in option C is incorrect.

Option D: The new equilibrium price for a box of gowns will be $100.

This option could be correct because the removal of tariffs on imported medical supplies could lead to an increase in supply, resulting in a lower equilibrium price. Therefore, if the demand for surgical gowns in the hypothetical city increases due to the pandemic and the removal of tariffs leads to an increase in supply, the new equilibrium price could be lower than the pre-pandemic level.

Option E: The removal of the tariff will increase demand.

This option is not correct because the removal of tariffs would likely lead to an increase in supply, which could lead to a decrease in price and an increase in quantity demanded. However, it is unlikely to increase demand directly.
