As a greenhouse gas that absorbs heat, CO2 raises the temperature of the atmosphere. We refer to this as global warming. The glaciers will melt more quickly as the world's temperature rises, raising sea levels and bringing on disaster. More power is consumed for air conditioning as the temperature rises, which further raises the air's CO2 level.
Since coal is the primary fuel utilized in the creation of power. This creates a vicious cycle.

Answer:
A. More hydrogen ions inside the membrane than outside it
Explanation:
During electron transfer from water molecule to PS II and then through electron transport chain to the PS I pumps the hydrogen ions inside the thylakoid lumen. ATP synthesis is driven by energy of proton concentration gradient that moves the hydrogen ions (protons) from lumen of thylakoid membrane towards the stroma. Hence, ATP synthesis requires presence of more hydrogen ions inside the membrane.
Answer:false
Explanation:the cell wall is a rigid , protective wall that surrounds the plasma membrane.
The rigidity of the cell wall is due primarily to the presence of cellulose and other materials such as lignin and pectin.
Cellulose is a polysaccharide and the plant cell wall is made up of several molecules of it.
Lignin is a rigid and impermeable material and deposited on the cellulose as an extra reinforcement on the cell wall.
Pectin are found in the middle lamellae and helps to cement the adjacent cell walls.
There is also hemicellulose which binds to the cellulose mifilaments.
The cell wall may also possesses plasmodermata,which are pores through which water and nutrients pass adjacent cells.
This rigid covering of the cell prevents it from expanding and shrinking due to water movement in and out of the cells
