In the given question we need to convert 0.075 meter into centimeter. For this purpose we need to know the relation between meter and centimeter. Then only this problem can be solved and the correct answer reached.
Now we know that
1 meter = 100 centimeter
Then
0.075 meter = [(100/1) * 0.075] centimeter
We know that any number when divided by 1 gives the same number.
So
0.075 meter = (100 * 0.075) centimeter
= (100 * 75/1000) centimeter
= (7500/1000) centimeter
= (75/10) centimeter
= 7.5 centimeter.
So from all the given options the correct answer to the question is 7.5 centimeter.
The number of electron energy levels in a magnesium atom is: <u>3</u>
<h3>What is electron energy level?</h3>
The set distances from an atom's nucleus where electrons may be found are referred to as energy levels (also known as electron shells). Higher energy electrons have greater energy as you move out from the nucleus. A region of space inside an energy level known as an orbital is where an electron is most likely to be located.
An electron rotating in a shell is connected with a particular amount of energy. When it moves from one energy level to another, or when it leaps to another shell, the energy changes. As a result, a shell also indicates an electron's energy along with its position, and these are known as energy levels.
The distribution of electrons in the electron shells for the magnesium atom is given as : 2,8,2.
So, the total number of energy levels are <u>3.</u>
Correct option: (c)

only metals above hydrogen
Explanation:
On the activity series, only metals above hydrogen will displace it in solution.
The activity series is a list of metals and non-metals that shows how reactive they are.
- Metals high in the series are highly reactive.
- Those that are down below are less reactive.
- As a rule of thumb, any metal higher than another in the series will displace it from the solution containing the lower metal.
- As with hydrogen, only metals that above it will displace it from solutions.
- Reactions of this kind are called single displacement reactions

Answer:
Bilateral: When something is bilateral it has two sides or it affects both sides of something. Discussions between two political parties are called bilateral because both sides get to share their views. Bilateral comes from Latin: bi means "two" and lateralis means "belonging to the side."
Endotherm: is an organism that maintains its body at a metabolically favorable temperature, largely by the use of heat set free by its internal bodily functions instead of relying almost purely on ambient heat
Subspecies: In biological classification, the term subspecies refers to one of two or more populations of a species living in different subdivisions of the species' range and varying from one another by morphological characteristics. ... In the wild, subspecies do not interbreed due to geographic isolation or sexual selection
Arthropod: Arthropoda, such as an insect, spider, or crustacean.
Micrometer: an instrument used with a telescope or microscope for measuring very small distances. 2 : an instrument having a rod moved by fine screw threads and used for making exact measurements. micrometer.
Hypothermia: Hypothermia is a potentially dangerous drop in body temperature, usually caused by prolonged exposure to cold temperatures. The risk of cold exposure increases as the winter months arrive. But if you're exposed to cold temperatures on a spring hike or capsized on a summer sail, you can also be at risk of hypothermia.
Polymorph: Polymorphism is the ability of a substance to crystallize into different crystalline forms. These crystalline forms are called polymorphs or crystalline modifications. Polymorphs have the same liquid or gaseous state but they behave differently in the solid state.
