Answer:
C
Explanation:
The ozone layer absorbs ultraviolet rays from the sun.
Answer:
Concentration of solution B is
Explanation:
Solution A: Total volume of solution A = (9.00+1.00) mL = 10.00 mL
According to law of dilution,
where and are initial and final concentration respectively. and are initial and final volume respectively.
Here = , = 1.00 mL, = 10.00 mL
So, =
So, concentration of solution A =
Solution B: Total volume of solution B = (2.00+8.00) mL = 10.00 mL
Similarly as above, =
So, concentration of solution B =
Explanation:

Answer:
Explained below:
Explanation:
The global temperature means the fluctuations in the temperature of the atmosphere and the oceans (existing in the earth surface).
Is the Earth’s global temperature is maintained or not depends on how much sunlight hits Earth versus and how much is returned, it also depends on the atmospheric level of carbon dioxide which prevents the earth from extreme cooling during the night.
<span>Nuclear reactions have two main types: fission reactions and fusion reactions. When two light nuclei are joined to create a heavier and more stable nucleus, this process is called the fusion reaction. In the fission reaction, the heavy nucleus split into two nuclei with a smaller mass number. In other words, fission is splitting of atoms although not all atoms undergo fission, only few went through normal circumstances (that is a fact). </span>
