A class 1 lever has the fulcrum positioned between the effort and resistance, allowing for the amplification of force or the achievement of balance.
The class of lever with the fulcrum located between the effort and resistance is called a class 1 lever. In this type of lever, the fulcrum is positioned in the middle, with the effort applied on one side and the resistance on the other. Class 1 levers are commonly seen in tools such as seesaws and crowbars. They can be used to amplify force or achieve balance. When the effort is applied closer to the fulcrum than the resistance, a mechanical advantage is gained, allowing a smaller effort to move a larger resistance. On the other hand, if the effort is applied farther from the fulcrum, a mechanical disadvantage is created, requiring a larger effort to move a smaller resistance.For more questions on force

Based on a cost–benefit analysis, society’s cost incurred due to _____
will be reduced as the amount of pollution _____
. However, at the same time, the cost of pollution control will increase.
Based on a cost-benefit analysis, society's cost incurred due to pollution will be reduced as the amount of pollution decreases. However, at the same time, the cost of pollution control will increase.
Pollution poses various negative impacts on society, including environmental degradation, health problems, and economic losses. To mitigate these effects, efforts are made to reduce pollution through measures such as stricter regulations, cleaner technologies, and sustainable practices.
As pollution levels decrease, society experiences several benefits. First and foremost, there is an improvement in public health. Reduced pollution means lower rates of respiratory diseases, cardiovascular issues, and other illnesses associated with pollution exposure. This leads to a decrease in healthcare costs, improved productivity, and an overall better quality of life for individuals.
Furthermore, a cleaner environment supports ecosystem health and biodiversity. Reduced pollution contributes to the preservation of natural resources, such as clean air, water, and soil. This, in turn, sustains the ecosystem services that support agriculture, tourism, and other economic activities.

In photosynthesis, the inputs include 6 carbon (C) atoms, 12 hydrogen (H) atoms, and 18 oxygen (O) atoms. These atoms are obtained from carbon dioxide ([tex]CO_{2}[/tex]) . Glucose [tex]C_{6} H_{12} O_{6}[/tex], which contains 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. Additionally, oxygen (O2) is released as a byproduct.In cellular respiration, the inputs are the same as the outputs of photosynthesis. This is because the products of photosynthesis, such as glucose and oxygen, serve as the inputs for cellular respiration. Glucose is broken down during cellular respiration to release energy. The process involves the consumption of 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. The energy released is captured in the form of adenosine triphosphate (ATP), which is the energy-carrying molecule used by cells for various metabolic processes.For more such question on photosynthesis
