What is Periodic table?All identified chemical elements are arranged in rows (referred to as periods) and columns (referred to as groups) in the periodic table of chemical elements, also known as the periodic table, in ascending order of atomic number.Groups are the names given to the periodic table's columns. In the table, individuals who belong to the same group make bonds of the same kind and have an equal number of electrons in their atoms' outermost shells. The periods refer to the horizontal rows.Elements in the periodic table can be divided into groups and eras. The periodic table is organized into horizontal rows for periods and vertical columns for groupings. As you advance, the atomic number grows.To learn more about Periodic table refer to:

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.

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.

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.
