Explanation;
-Semi-permeability is one of the features of a cell membrane, which means that the membrane allows selective movement of materials in and out of the cell; that is only certain molecules can enter or leave the cell.

What about blood group?</h3>
- According to the presence or absence of antibodies and hereditary antigenic compounds on the surface of red blood cells, blood is classified according to its type.
- Depending on the blood group system, these antigens could be proteins, carbohydrates, glycoproteins, or glycolipids.
- The genes that a person got from their parents determine what blood type they have.
- There are numerous systems for classifying blood types, but ABO is the most popular one.
- The ABO group is divided into four main categories: A, B, O, and AB.
- There are eight more blood types within these groupings.
- Each of the eight blood types has a particular ability to save lives.
- The majority of people (37% of the population) have the blood type O+, which is the most prevalent. This indicates that there is a greater need for this blood type for blood transfusions.

Electricity is the flow of electrical power or charge. Everyday, we use electricity to do many jobs for us from lighting and heating/cooling our homes, to powering our televisions and computers. We get electricity from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources. Electricity can be broken down into some very simple, natural elements. The biggest of which is the atom. Atoms are everything.
Not only that we are made of atoms, but atoms are everywhere. It's a known fact that almost anyone should know.
