Answer:
carbon dioxide in the atmosphere
Explanation:
Carbon dioxide in the atmosphere is the major cause of greenhouse effect.
Greenhouse effect is the main cause of global warming.
- This effect is produced as a result of some certain gases called greenhouse gases.
- These gases are carbon dioxide, water vapor, methane etc.
- They prevent short wave radiations from leaving the earth.
- This causes the increase in temperature of the surface.

The circulatory system collects metabolic wastes from the blood, which will be eliminated by the kidneys through urine.
The kidneys are responsible for the elimination of waste, acids and excess fluid from the body, maintaining the balance of water, salts and minerals. Blood flows into the kidney through the renal artery.
<em>Answer:</em>
- Such a alkane has only one ring that is cyclooctane.
<em>Explanation:</em>
- The general formula of alkane is CnH2n+2. Such general formula is applicable for only open chain alkane.
- When alkane form ring, then this formula does not remain valid.
- The general formula of Cycloalkane is CnH2n.
As in this case, there are 8-carbon and 16-hydrogen that is according to above cycloalkane formula.
<span>The only effect that it has is when the magma is cooling (so if it's on the surface, it's now lava), any magnetic elements will align their dipoles with the north and south poles of the magnetic field.

Answer:
= 5.26 × 10^-7 M
Explanation:
We know that;
[H3O+][OH-] = 1 x 10^-14
Therefore;
Given; OH− concentration = 1.9x10^−8 M
Then; [H3O+] = (1 x 10^-14)/[OH-]
= (1 x 10^-14)/(1.9x10^−8)
= 5.26 × 10^-7 M
