What else can I help you with?
True or false the main carbon cycle is conversion from carbon dioxide to living matter and back to carbon dioxide?
True. The main carbon cycle involves the conversion of carbon dioxide into living matter through photosynthesis by plants, which is then released back into the atmosphere as carbon dioxide through respiration and decomposition processes.
True or false removal of forests reduces the earth ability to absorb carbon dioxide from the atmosphere?
True. Forests play a crucial role in absorbing carbon dioxide from the atmosphere through the process of photosynthesis. When forests are removed, this natural carbon sink is diminished, leading to an increase in carbon dioxide levels in the atmosphere.
Magnesium will not decompose when heated to form magnesium oxide and carbon dioxide?
Magnesium will actually decompose when heated to form magnesium oxide and carbon dioxide. This is a common chemical reaction where magnesium reacts with oxygen from the air to form magnesium oxide, and if there is any carbon present, it can also react to form carbon dioxide.
How do carbon dioxide molecules enter the light dependent reactions?
Carbon dioxide molecules enter the light-dependent reactions of photosynthesis through tiny pores on the underside of leaves called stomata. Once inside the leaf, carbon dioxide diffuses into the chloroplasts where it participates in the Calvin cycle to produce sugars.
Is it true or false that the carbon dioxide level in the atmosphere has been increasing since 1900?
True. The carbon dioxide level in the Earth's atmosphere has been increasing since around 1900 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.
What brings air into the body and removes carbon dioxide?
Carbon Dioxide
Do The Krebs cycle produces NAD electron carriers and carbon dioxide true or false?
false. it produces ATP, electron carriers and carbon dioxide.
The exchange of carbon dioxide and oxygen in the lungs is called perspiration.?
False.
Acid rain is a product of carbon dioxide and rain.?
false
When carbonic acid decomposes carbon monoxide is one of the products true or false?
False. When carbonic acid decomposes, one of the products is carbon dioxide, not carbon monoxide. Carbonic acid (H2CO3) breaks down into water (H2O) and carbon dioxide (CO2).
Ash and carbon dioxide coming from the volcano contributes to atmospheric cooling, True or false?
False
Diamond and quartz are both minerals composed of a single element true or false?
False. Diamond and quartz are minerals composed of multiple elements. Diamond is composed of carbon atoms, while quartz is composed of silicon and oxygen atoms.
Is leaves of trees provide freash air because the get rid of carbon dioxide true or false?
is leaves of trees provide fresh air because the get rid of carbon dioxide true or false
Is The exchange of carbon dioxide and oxygen in the lungs is called perspiration.?
False.
Do the lungs exchange carbon dioxide and oxygen true or false?
True
True or false photosynthesis produces the carbon dioxide that most living things need to survive?
FALSE
A catalyst for automobile exhausts removes carbon dioxide. True or False?
that is true
