Photosynthesis

фотосинтез

What is photosynthesis? The process of photosynthesis is one of the most important biological processes occurring in Nature. Organic substances are formed from carbon dioxide and water under the action of light; this phenomenon is called photosynthesis. The release of oxygen (vital for the existence of life on our amazing planet) is the most important product of photosynthesis.

Ozone Holes: Causes and Consequences

Ozone Holes

The planet Earth is unique in the Solar System because it is the only planet with life. The appearance of life on Earth was possible thanks to a special protective layer of ozone, which covers our planet at an altitude of 20-50 km. What is ozone? Why is ozone important? The word “ozone” means “smelling” in Greek – it is the smell we can sense after the rain. Ozone is a blue gas consisting of three-atom molecules of oxygen, so ozone is very concentrated oxygen. The importance of ozone is enormous because it protects the Earth from the harmful effects of ultraviolet rays coming from the Sun. Unfortunately, we (people) do not appreciate what was created by Nature (or God) for billions of years, and the appearance of ozone holes was one of the results of the human devastating activity.

Cell Membrane

Cell Membrane

It’s no secret that all living beings on our planet are made up of cells, these countless “atoms” of organic matter. The cells, in turn, are surrounded by a special protective membrane, that plays a very important role in the life of the cell. Functions of the cell membrane are not limited only to the protection of the cell, but constitute the most complex mechanism involved in the reproduction, nutrition, and regeneration of the cell.

June Bug (Cockchafer, May Beetle, Chafer Beetle)

June Bug

The June bug (also known as the cockchafer, May beetle, May bug or chafer beetle) is especially well known to gardeners and not from the best side since it is one of the most dangerous pests. This insect got its name due to the habit of appearing in the spring. In May-June, the June bug begins its active work. What are the habits of the June bug? What is its appearance? How to get rid of May beetle? We’ll talk about this in our article.

Vacuole

Vacuole

Vacuoles are one-membrane cellular organelles and important components of a eukaryotic cell (the eukaryotic cell has a nucleus and a membrane – outer shell). However, not all eukaryotic cells have vacuoles among their organelles. Vacuoles are mainly found in plant and fungal cells. Do animal cells have vacuoles? Yes, animal cells do have vacuoles, but they are smaller, larger in number (plant cells usually have just one or a few large vacuoles) and serve a somewhat different purpose than those of plants.

Universal Law of Gravitation

Newton's apple

It is not a secret for anyone that the law of universal gravitation was discovered by the great English scientist Isaac Newton. According to legend, he was walking in the garden. At that moment, an apple fell from the tree (in one version it fell directly on the head of a physicist, in another it simply fell). Later this apple became famous Newton’s apple. An apple that fell on Newton’s head inspired the discovery of the law of universal gravitation because the Moon in the night sky was not falling, but the apple fell. The scientist probably thought that some force acts on the Moon (causing it to rotate in orbit), and some force acts on the apple, causing it to fall to the ground.

Chemical Reactions

Chemical Reactions

Chemical reactions (their properties, types, flow conditions, etc.), are the cornerstones of an interesting science called chemistry. Let’s find out what a chemical reaction is and what happens in a chemical reaction. So, the chemical reaction in chemistry is considered to be the conversion of one or several substances into other substances. At the same time, the nuclei of atoms do not change (unlike nuclear reactions). During chemical reactions there is a redistribution of electrons and nuclei, new chemical elements appear.
