Tonicity is responsible for determining which direction water will diffuse across the plasma membrane of cells.
I believe the correct response would be A. Elements arranged by increasing atomic mass, this was not included in Dmitri's periodic table. Since elements are arranged according to atomic number, the heavier elements are in fact placed in the rows closer to the bottom of the table.
The answer is 10 O2, it should de 13 O2.
To know if a reaction is well balanced between the reactants and the products, you have to calculate the number of atoms of each element on both sides of the reaction and to check if they are equal.
*For carbon, on both sides, there are 8 carbon atoms.
*For hydrogen, on both sides there are 20 hydrogen atoms.
*For oxygen, there are 20 oxygen atoms in the reagents and 26 in the products, so it is necessary to increase the number of oxygen in the reactants (without touching the others). For this we put 13 O2 in the reactants instead of 10, to have 26 oxygen atoms on each side.

Answer: A) Solar</h3>
=========================================================
Explanation:
The sources of wind, hydro, and fossil fuels all use a turbine. So we can rule out choices B,C, and D.
A turbine is basically a wheel that spins to generate motion energy into electrical energy. Think of it like one of those stationary bicycles and the bike powers up a nearby lamp (the faster you pedal, the brighter the bulb gets). Another example that's similar to a turbine would be those flashlights where you can rotate a crank to have the light come on (which is useful for when the batteries are completely dead). The windmill blades act as a giant turbine that the wind spins around. Hydroelectric turbines are spun by the falling water. Fossil fuels are burned to create very hot steam which then powers a turbine. Even nuclear power uses turbines as well. With fossil fuels and nuclear energy, the idea is to heat up a vat of water and then turn that intensely hot steam into electrical energy through a turbine.
With solar panels however, the electrical energy is converted through a process of sunlight interacting with the solar cells that <u>doesn't require a turbine</u>. This explains why you can use solar panels to power up devices such as phones or laptops without having any moving parts. All you need is a flat set of solar panels.
There is a slight variation of solar power known as "concentrated solar power", aka "concentrated solar thermal", where solar panels are not used. Instead, a vast array of mirrors are set up to aim the suns rays at a very specific narrow area. Think of it like a magnifying glass to focus the suns rays. The place where the narrow beam hits has a very high temperature. This high temperature heats up water to turn to steam, and the process from here is effectively the same as fossil fuels or nuclear energy. So that means turbines are involved with concentrated solar power. I'm assuming your teacher is specifically referring to solar panels when they mentioned choice A.
The answer is <em><u>not</u></em> Organisms would be classified based only on physical characteristics!!
I strongly feel that it would be....
<em>--the existing classification system may change to accommodate the new information.--</em>
<em>Reason:</em> Some things would not just be classified by appearance. Rather, this would add more possibilities to classification. We know that plants and dogs look nothing alike yet they are still related through the Domain (Eukarya).
I also took this test and relied on the other answer, sadly, it was incorrect.
I hope i could help! Let me know if this is incorrect. ~ Ninja Cat :D
