Fossil fuels are made from the decomposition of plants and animals. These fuels are present in the earth's crust and contain carbon and hydrogen which is usually burned to obtain energy. Nuclear Power comes now in the place of fossil fuels. The correct option is A.
The use of nuclear reactions to generate the electricity is defined as the nuclear power. The nuclear fission, nuclear fusion and nuclear decay results in the formation of nuclear power. Now a days majority of the electricity from nuclear power plants is produced by the fission of uranium and plutonium.
The nuclear power plants heat water to produce steam. The steam is used to rotate large turbines which generate electricity. They use heat produced during nuclear fission to heat water. The nuclear power is the clean and efficient way of boiling water to form steam.
Thus the correct option is A.

Answer:
Nuclear Power
Explanation:
The job a part does within an organism, whether it is a cell, tissue, organ, or organ system, is crucial for the life and health of the organism. Each part is designed to carry out certain functions, which collectively ensure the organism’s survival, growth, and reproduction.
The role a part plays within an organism, also known as its function, depends on whether the part is a cell, tissue, organ, or organ system. In a multicellular organism, all parts work together to maintain the life and health of the entire organism. For example, an organ such as the heart has the function of pumping blood to distribute nutrients and oxygen around the body.
Each part is uniquely designed to suit its function. A living organism is capable of performing all physiologic functions independently, and these functions are determined by the anatomy (structure) and physiology (functionality) of its cells, tissues, organs, and organ systems.

Answer:
Usually lung cancer.
Explanation:
It causes cells in your lungs to be damaged, which can lead to lung cancer.
Usual symptoms include
persistent cough
coughing up blood
wheezing
shortness of breath
hoarseness
chest pain, especially when you cough or laugh
frequent infections such as bronchitis and pneumonia
Radon is part of the environment and generally isn’t harmful. But long-term exposure to high levels of radon can put you at risk of developing lung cancer, especially if you smoke
Answer:
0.172 mol·L⁻¹
Step-by-step explanation:
1. Write the chemical equation for the reaction.
HBr + LiOH ⟶ LiBr + H₂O
===============
2. Calculate the moles of LiOH
c = n/V Multiply each side by V
n = Vc
V = 0.0375 L
c = 0.215 mol·L⁻¹
Moles of LiOH = 0.0375× 0.215
Moles of LiOH = 8.062 × 10⁻³ mol LiOH
===============
3. Calculate the moles of HBr
1 mol HBr ≡ 1 mol LiOH
Moles of HBr = 8.062 × 10⁻³× 1/1
Moles of HBr = 8.062 × 10⁻³ mol HBr
===============
4. Calculate the molar concentration of the HBr
V = 47.0 mL = 0.0470 L
c = 8.062 × 10⁻³/0.0470
c = 0.172 mol·L⁻¹
The molarity of the HBr solution is 0,172 M.
The neutralization reaction between LiOH and HBr is the following:
HBr(aq) + LiOH(aq) → LiBr(aq) + H₂O(l)
Answer:
3.325×6.022×1023=2×1024 3.325 × 6.022 × 10 23 = 2 × 10 24 atoms.
