Genetic Diversity
• The variation in genes that exists within a species
• Organisms with a large gene pool have a greater
chance of surviving and flourishing than a
population with limited genetic variability.
• Ex: resistance to disease, tolerance to cold
• Darwin termed this process "natural selection."
To the left you can see the variety of genes that exist
in types of fruit. Can you think of another species

25.2 g of CuSO4 6H20 (mm: 267.72 g/mol) is dissolved in 28.0 mL of water, calculate the molarity.
Answer:
3.36 M
Explanation:
Step 1: Given data
Mass of CuSO₄.6H₂O (m): 25.2 gMolar mass of CuSO₄.6H₂O (M): 267.72 g/molVolume of solution (V): 28.0 mL (we will assume it is equal to the volume of water)Step 2: Calculate the moles (n) of CuSO₄.6H₂O (solute)
We will use the following expression.
n = m/M
n = 25.2 g / (267.72 g/mol) = 0.0941 mol
Step 3: Calculate the molarity
Molarity is equal to the moles of solute divided by the liters of solution.
M = 0.0941 mol/0.0280 L = 3.36 M

3. Explain why ionic compounds are "fixed" in their chemical composition.
Answer: Ionic compounds are "fixed" in their chemical composition as forces present between atoms of these compound are strong electrostatic forces of attraction due to which these compounds have fixed chemical composition.
Explanation:
Compounds formed by transfer of electrons from one atom to another are called ionic compounds.
For example, sodium atom on losing its one valence electron forms [tex]Na^{+}[/tex] ion and when a chlorine atom gains this electrons then it forms [tex]Cl^{-}[/tex] ion. These ions when come closer then an electrostatic force of attraction will pull them together forming NaCl compound.
Therefore, one atom of sodium is chemically combining to one atom of chlorine to form NaCl.
As the forces present between atoms of an ionic compound are strong electrostatic forces of attraction due to which these compounds have fixed chemical composition.
Thus, we can conclude that ionic compounds are "fixed" in their chemical composition as forces present between atoms of these compound are strong electrostatic forces of attraction due to which these compounds have fixed chemical composition.
Ionic compounds are formed when there is a donation of an electron from one element to another that receives the electron. This causes the donating atom to attain a positive charge and the receiving atom to attain a negative charge. The ions thus formed are held by strong electrostatic forces that hold them together.
Ionic bonds are formed through the transfer of electrons from one element to another which receives the electron.Positive and negative ionic charges are thus acquired by the respective elements. Strong electrostatic forces that act in all directions hold the ions together. This also gives them the fixed state that makes it more difficult to break them up when compared to the covalent bonds. So, the strong electrostatic forces cause the fixed state of ionic compounds.

What is the coefficient in front of the O₂ when the equation below is balanced C₂H₆O₂(g) + O₂ (g) → CO₂(g) + H₂O (g)
Answer:
The balanced equation is:
2C₂H₆O₂ (g) + 5O₂ (g) → 4CO₂ (g) + 6H₂O (g)
Therefore, the coefficient in front of O₂ when the given equation is balanced is 5.
Explanation:
In order to balance a chemical equation, it is necessary to ensure that there is an equal number of atoms for each element on both sides of the equation. This can be achieved by adding coefficients to chemical symbols or formulas as required.
Given equation:
C₂H₆O₂ (g) + O₂ (g) → CO₂ (g) + H₂O (g)
This equation is not balanced, because there are:
2 carbon atoms on the left side of the equation and only one on the right side.6 hydrogen atoms on the left side of the equation and only 2 on the right side.4 oxygen atoms on the left side of the equation and only 3 on the right side.Add the coefficient 2 in front of CO₂ and the coefficient 3 in front of H₂O on the right side of the equation:
C₂H₆O₂ (g) + O₂ (g) → 2CO₂ (g) + 3H₂O (g)
The carbon and hydrogen atoms are now balanced, but there are 4 oxygen atoms on the left side and 7 oxygen atoms on the right side. To balance the equation, double the coefficients on the right side and add the coefficient 2 in front of C₂H₆O₂ on the left side of the equation:
2C₂H₆O₂ (g) + O₂ (g) → 4CO₂ (g) + 6H₂O (g)
Now we have 6 oxygen atoms on the left side and 14 oxygen atoms on the right side. So if we add the coefficient 5 in front of O₂, there are14 oxygen atoms on the left side, and thus the equation is balanced.:
2C₂H₆O₂ (g) + 5O₂ (g) → 4CO₂ (g) + 6H₂O (g)
[tex]\begin{array}{|l|c|c|}\cline{1-3}\vphantom{\dfrac12}&\sf Left\;side&\sf Right\;side\\\cline{1-3}\vphantom{\dfrac12}\sf Carbon&2 \times 2=4&4\\\cline{1-3}\vphantom{\dfrac12}\sf Hydrogen&2 \times 6=12&6 \times 2=12\\\cline{1-3}\vphantom{\dfrac12}\sf Oxygen& 2\times 2+5 \times 2=14&4 \times 2+6 =14\\\cline{1-3}\end{array}[/tex]
Therefore, the coefficient in front of O₂ when the given equation is balanced is 5.

Which component of the universe contains all of the other components listed below and would have the
greatest mass?
The galaxy is the component of the universe which contains all of the other components and would have the greatest mass.
What is a galaxy?A galaxy is a system of stars, stellar remnants, interstellar gas, dust, dark matter, bound together by gravity.The word is derived from the Greek galaxias , literally 'milky', a reference to the Milky Way galaxy that contains the Solar System. Galaxies, averaging an estimated 100 million stars, range in size from dwarfs with less than a hundred million stars, to the largest galaxies known – supergiants with one hundred trillion stars,each orbiting its galaxy's center of mass.
Most of the mass in a typical galaxy is in the form of dark matter, with only a few percent of that mass visible in the form of stars and nebulae. Supermassive black holes are a common feature at the centres of galaxies.
