What chemical triggers your brain to control breathing?
The primary chemical that triggers the brain to control breathing is carbon dioxide (CO2). As CO2 levels rise in the blood, it leads to a decrease in pH, making the blood more acidic. This change is detected by chemoreceptors in the body, which signal the brain, particularly the medulla oblongata, to increase the rate and depth of breathing to expel excess CO2 and restore normal levels. Oxygen levels also play a role, but CO2 is the main driver for regulating breathing.
What are the key effects supposed to be of global warming?
Global warming is an increase in the earth's temperature caused by an increase of CO2 gases in the amosphere. This increase in temperture has affected the earth in a number of ways, one example is that the ice caps are now melting due to the temperature rise, which in turn has caused sea levels to rise.
Will the rise in carbon dioxide cause the surface temperature to rise?
Yes, the rise in carbon dioxide (CO2) levels in the atmosphere contributes to an increase in surface temperatures through the greenhouse effect. CO2 traps heat radiated from the Earth's surface, preventing it from escaping into space, which leads to warming. This phenomenon is a key driver of climate change, resulting in various environmental impacts. As CO2 concentrations continue to rise, we can expect further increases in global temperatures.
What would be a direct affect of increase in the amounts of this gas?
An increase in the amounts of carbon dioxide (CO2) in the atmosphere would lead to enhanced greenhouse effect, resulting in global warming. This rise in temperature can cause climate change, leading to more frequent and severe weather events, rising sea levels, and disruptions to ecosystems. Additionally, higher CO2 levels can affect ocean acidity, impacting marine life and biodiversity.
Why might an increase in atmospheric CO2 result in an increase in global temperatures?
This is so because CO2 is a green house gas which does not allow the harmful UV rays of the sun trapped by the Earth to go back , which increases the temperature of the Earth. So if carbon dioxide will increase , surely the temperature would also increase.
When blood CO2 levels increase does the pH increase or decrease?
When blood CO2 levels increase, it leads to an increase in hydrogen ion concentration, which lowers pH, making it more acidic. This phenomenon is known as respiratory acidosis.
How does an increase in CO2 levels affect pH levels in the environment?
An increase in CO2 levels in the environment can lead to a decrease in pH levels, making the environment more acidic. This process is known as ocean acidification and can have harmful effects on marine life and ecosystems.
How does the increase or decrease of CO2 levels affect the pH balance in the environment?
When CO2 levels increase, more carbonic acid is formed in the environment, leading to a decrease in pH levels, making the environment more acidic. Conversely, when CO2 levels decrease, the pH balance tends to become more alkaline.
What is the main stimulus for breathing?
The main stimulus for breathing is the level of carbon dioxide (CO2) in the blood. As CO2 levels rise, it leads to an increase in acidity (lower pH), which is detected by chemoreceptors in the brain and blood vessels. This triggers the respiratory center in the brain to increase the rate and depth of breathing to expel excess CO2 and restore normal levels. While oxygen levels also play a role, they are secondary to the regulation of CO2.
Does CO2 levels in the atmosphere rise or fall over time?
Carbon dioxide (CO2) levels in the atmosphere have been rising over time due to human activities such as burning fossil fuels and deforestation. This increase in CO2 is a major contributor to global warming and climate change.
What do CO2 and atmospheric CO2 levels and the global temperature from the last 150 years have in common?
They're both increasing, in pretty good correlation with each other. Most of the increase in carbon dioxide is a result of human activities. Additionally, and similarly, much of the observed increase in temperature is a result of humans.
What will happen to CO2 levels if light is blocked from reaching leaves?
Co2 levels will rise as a result of both animal and plant respiration

When you hold your breath for half a minute the carbon dioxide concentration kn the blood?
When you hold your breath for half a minute, carbon dioxide (CO2) levels in the blood begin to rise because it is still being produced by cellular metabolism but not being expelled through breathing. This increase in CO2 leads to a corresponding decrease in blood pH, making the blood more acidic. The body detects this rise in CO2 and the drop in oxygen levels, eventually triggering the urge to breathe in order to restore normal gas exchange.
What causes an increase in CO2 levels inside a house?
An increase in CO2 levels inside a house can be caused by poor ventilation, burning fossil fuels, and the presence of many people or pets.
What is the relationship between CO2 levels and pH?
As CO2 levels increase in the atmosphere, more CO2 is absorbed by the oceans, leading to ocean acidification. This process reduces the pH of the oceans, making them more acidic. The lower the pH, the higher the acidity, which can have detrimental effects on marine life and ecosystems.
