carbon dioxide
Oxygen makes up about 21% of the Earth's atmosphere by volume. This level has been relatively consistent for the past few million years and provides the necessary amount of oxygen for humans and many other organisms to survive.
Because due to the over pollution and cutting down the tree's level of Oxygen is decreasing .The level of Nitrogen always remains constant in the atmosphere . The level of Nitrogen doesn't' depend on the level of the Oxygen level.
The pH level for most humans is around 7.4, which is slightly alkaline. The body tightly regulates pH levels to maintain homeostasis and proper function of organs and systems. Any significant deviations from this range can be harmful to health.
The current oxygen concentration in the Earth's atmosphere has been relatively stable at around 21% for the past 300 million years. This level is maintained through processes like photosynthesis by plants and phytoplankton, which convert carbon dioxide into oxygen.
That is ozone.
Humans have greatly increased the level of carbon dioxide in the atmosphere. This is primarily due to the burning of fossil fuels for energy production, transportation, and industrial activities. This increase in carbon dioxide is a major contributor to global warming and climate change.
Humans have greatly increased the level of carbon dioxide in the atmosphere through activities such as burning fossil fuels, deforestation, and industrial processes. This has led to the greenhouse effect and global warming, resulting in climate change and its associated impacts on the environment and societies worldwide.

False. Increased frequency refers to the number of times a specific training session or exercise is performed within a given time frame, not the level of intensity or difficulty of the training.
The level of carbon dioxide in the atmosphere has increased significantly over the past century due to human activities such as burning fossil fuels and deforestation. This increase in carbon dioxide is a major contributor to global warming and climate change.
If humans continue to do nothing to reduce their impact on the carbon cycle, the level of carbon in the atmosphere will continue to increase. This will lead to a rise in global temperatures, resulting in more severe climate change impacts such as extreme weather events, sea-level rise, and loss of biodiversity.
True. Increased intensity refers to the extent to which the level of training is raised, such as by adding more weight, increasing repetitions, or shortening rest periods. It is an important factor in progression and adaptation in exercise.
Increased frequency refers to how often a particular training session or exercise is performed within a timeframe. It does not directly relate to the level or intensity of training, but rather to the number of times a specific routine is repeated.
The highest safe decibel level for humans is around 85 decibels for prolonged exposure. Above this level, there is an increased risk of hearing damage. Sound levels above 120 decibels can cause immediate harm to hearing.
