Answer:
D, to repair the damged cells is noy a reason that cells reproduce by siving in order to maintaon homeostasis.
Explanation:
B. The heat from the reaction turns water to steam, which runs a generator.
<h3>Explanation</h3>
Here's what's going on within a <em>typical</em> nuclear power plant.
- The fuel bundle undergoes fission to release heat.
- A coolant such as molten salt flows across the reactor and transfers heat away from the fuel.
- The coolant is then passed into a heat exchanger. Cold water goes through the heat exchanger to absorb the heat. The coolant cools down and is recycled. Water heats up and boils to produce steam.
The rest of this process resembles that of a coal power plant.
- Steam from the heat exchanger goes through a turbine, which drives a generator.
- Some water condenses and is recycled.

Answer:
0.024M
Explanation:
Data obtained from the question include:
C1 = 6M
V1 = 2mL
C2 =?
V2 = 500mL
The molarity of the diluted solution can be obtained as follows:
C1V1 = C2V2
6 x 2 = C2 x 500
Divide both side by 500
C2 = (6 x 2) /500
C2 = 0.024M
The molarity of the diluted solution is 0.024M

The unknown compound consists of only carbon and hydrogen. The oxygen comes from the air. So you need to first determine the relative moles of hydrogen and carbon that are present in the CO2 and H2O. First, look up the molar masses of Carbon, Hydrogen, and Oxygen. Then determine the molar masses of CO2 and H2O.
Carbon = 12.0107
Hydrogen = 1.00794
Oxygen = 15.999
Molar mass of CO2
1 * 12.0107 + 2 * 15.999 = 44.0087
Molar mass of H2O
2 * 1.00794 + 1 * 15.999 = 18.01488
Number of moles of CO2
22.1 g / 44.0087 g/mol = 0.502173
Number of moles of H2O
10.5 g / 18.01488 g/mol = 0.582852
Since there's 1 carbon atom per CO2 molecule, there are 0.502173 moles of carbon.
Since there's 2 hydrogen atoms per H2O molecule, there are 2 * 0.582852 = 1.165703 moles of hydrogen.
Now we need to find a simple ratio of small integers that comes close to the ratio of 0.502173 / 1.165703 = 0.43079 to determine the empirical formula.
3/7 = 0.428571, an error of only 0.002219. The next closest ratio has an error of 0.013654, over 6 times larger.
So the empirical formula is C3H7</span>
