Answer and Explanation:
The signs that prevent us from swimming on the beach are signs that indicate some kind of danger, which can compromise our life, the well-being and the fun that the beach can provide. In other words, these signs are danger signs and are presented to keep us safe. The last time I went to the beach, I saw a sign that forbade people from entering the water because there were sharks in it, but recently, we can see many signs that prevent us from entering places without wearing a respiratory protection mask. This is done as a prevention to coronavirus.

How to Calculate Magnification on a Light Microscope
Updated April 30, 2018
By Karen G Blaettler
Microscopes magnify the tiniest inhabitants of this world. From the minute details of cells to the delicate cilia of paramecium to the intricate workings of Daphnia, microscopes reveal many miniscule secrets. Calculating total magnification uses simple observation and basic multiplication.
Basic Microscope Design
Microscopes use lenses to magnify objects. A simple microscope uses only one lens; a magnifying glass could be called a simple microscope. The magnification of a simple microscope doesn't need any calculation because the single lens is usually labeled. A hand-lens, for example, might be labeled with 10x, meaning the lens magnifies the object to look ten times larger than the actual size.
Compound microscopes use two or more lenses to magnify the specimen. The standard school microscope combines two lenses, the ocular and one objective lens, to magnify the object. The ocular or eyepiece is found at the top of the body tube. The objective lens points down toward the object to be magnified. Most microscopes have three or four objective lenses mounted on a rotating nosepiece. Rotating the nosepiece lets the viewer change the magnification. Different objective lenses provide different magnification options.

Finding Lens Magnification
Finding the magnification of each lens requires examining the casing of each lens. On the side of the casing is a series of numbers that includes a number followed by x, as 10x. This 10x shows that the lens magnifies an object to appear ten times larger than reality. Depending on the manufacturer, this magnification number may appear at the beginning or at the end of the number sequence. To calculate total magnification, find the magnification of both the eyepiece and the objective lenses. The common ocular magnifies ten times, marked as 10x. The standard objective lenses magnify 4x, 10x and 40x. If the microscope has a fourth objective lens, the magnification will most likely be 100x.
Calculating Magnification
Once the magnification of each individual lens is known, calculating total magnification is simple math. Multiply the magnification of the lenses together. For example, if the eyepiece magnification is 10x and the objective lens in use has a magnification of 4x, the total magnification is 10 × 4 = 40. The total magnification of 40 means that the object appears forty times larger than the actual object. If the viewer changes to the 10x objective lens, the total magnification will be the ocular's 10x magnification multiplied by the new objective lens's 10x magnification, calculated as 10 × 10, for a total magnification of 100x.

Explanation:
All living and nonliving things are made of matter and all matter consist of microscopic particles called atoms. Life, in connection to matter, requires a constant supply of matter. Matter can exist in different states, and plasma is a state of matter that composes the bulk of the entire universe. Matter is conserved and stores energy.
To sum up everything, human beings are made up of matter and so is everything else in the universe. Matter is life and it is true to say that “Matter makes up reality”. It is not objectively important or unimportant, it is only valuable as it is to the observer.
Matter is fundamental to the universe's existence and functioning. It comprises all physical substances, from atoms to galaxies, forming stars, planets, and life itself.
Matter's gravitational pull shapes the cosmos, creating galaxies, clusters, and cosmic structures. Stars, fueled by matter, produce energy and light, driving the universe's dynamics. Planets, including Earth, sustain life due to matter's interactions and chemical properties.
From the smallest subatomic particles to the vastness of cosmic bodies, matter plays a crucial role in shaping the universe's evolution and complexity. Understanding the properties and behavior of matter deepens our comprehension of the universe's past, present, and future.
Therefore, matter is fundamental to the universe's existence and functioning.
