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
that has similar variations?

Answer:
Oranges
Explanation:
Oranges have a lot of genetic diversity within them, since oranges were already well versed in growing in winter months, oranges have gentically modified themselves through natural selection into be able to prouduce in warmer climates. Oranges also have changes in genetics which gives them a lot of gentic diversity that effects their, size, taste, texture, acidity and ability to reproduce.

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.

O 5:4
Answer:
5:4
Explanation:
The equation given is balanced. There are 5 O2's on the left (reactant side) and then 4 H2O's on the right (product side). Thus, it's a 5:4 ratio.
how many periods are there in the modern periodic table of elements?
Answer:
There are seven periods in the modern periodic table.
Answer:
Seven periods
Explanation:
There are seven periods in the periodic table, with each one beginning at the far left. A new period begins when a new principal energy level begins filling with electrons. Period 1 has only two elements (hydrogen and helium), while periods 2 and 3 have 8 elements.

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.

A gas mixture contains oxygen, nitrogen, and carbon dioxide. It has a pressure of 250 mmHg. If the pressure of oxygen is 50 mmHg and the pressure of nitrogen is 175 mmHg then what is the pressure for carbon dioxide?
Answer:
[tex]P_{CO_2}=25mmHg[/tex]
Explanation:
Hello there!
In this case, according to the Dalton's law, which explains that the total pressure of a gaseous system equals the sum of the partial pressures of the gases composing, for the gaseous mixture composed by oxygen, nitrogen and carbon dioxide it would be possible to write:
[tex]P_{tot}=P_{N_2}+P_{O_2}+P_{CO_2}[/tex]
Now, given the pressure of the system and those of oxygen and nitrogen, we calculate that of carbon dioxide as shown below:
[tex]P_{CO_2}=P_{tot}-P_{N_2}-P_{O_2}\\\\P_{CO_2}=250mmHg-50mmHg-175mmHg\\\\P_{CO_2}=25mmHg[/tex]
