Answer:
Carbon dioxide is added to the atmosphere by human activities. When hydrocarbon fuels ( wood, coal, natural gas, gasoline, and oil) are burned, carbon dioxide is released. During combustion or burning, carbon from fossil fuels combine with oxygen in the air to form carbon dioxide and water vapor.
These natural hydrocarbon fuels come from once-living organisms and are made from carbon and hydrogen, which release carbon dioxide and water when they burn.
Explanation:
So the answer is Fossil Fuels.
Because bryophytes do not have a vascular tissue they
D) grow close to the ground
In order for cells to become whole organisms, they must divide and differentiate. Cells divide all the time. That means that just one cell, a fertilized egg, is able to become the trillions of cells that make up your body, just by dividing. Those trillions of cells are not all the same though.
Just a little while after you started out as a fertilized egg, your cells started performing specific tasks, even started to look different because of that. Differentiation means that one cell performs a different function than another cell, depending on where it is in your body.
Not sure if this will help.
So the teachers ratio was 9 yellow: 6 blue, which can be simplified to 3 yellow :2 blue
Gina's ratio was 4 yellow: 3 blue
They are not the same
teacher- 3:2
Gina- 4:3
This ratio is in terms of yellow to blue
