Species: Describe Its Types, & Examples

A species is a group of organisms with a genetic inheritance that can cross and create breeding offspring. Different species are separated from each other by a reproductive barrier. These barriers may be geographical barriers, such as mountains that separate two populations, or genetic barriers that do not allow reproduction between two populations. Throughout history, […]

prokaryotic cells vs eukaryotic cells: Define its Structure and Examples

The basic difference between prokaryotic and eukaryotic replication is that prokaryotic replication takes place inside the cytoplasm, the difference between prokaryotic and eukaryotic replication has the same origin of replication and that DNA eukaryotic replication is required in the gyrase, and in eukaryotic replication. it happens. Replication has many origins in the nucleus. Replication does […]

Immune System: Definition, Function, Disease, and Types

The immune system is the body’s defense against infection. The immune system (ih-MYOON) attacks bacteria and helps us stay healthy. or Collection of internal structures and processes — to prevent diseases or other foreign objects that may be damaged. During normal operation, the immune system recognizes various threats, including viruses, bacteria, and parasites, and distinguishes […]

Fungi: Definition, Types, and Structure

Fungi is a state usually made up of multicellular eukaryotes. They are heterotrophic organisms (cannot make food by themselves) and play an important role in the nutrient cycle in ecosystems. Fungi can breed sexually and botanically, and they also mate with plants and bacteria. However, they are also responsible for some diseases of animals and […]

Chromosome: Describe its Structure

In the nucleus of each cell, DNA molecules are packed into linear structures called chromosomes. Each chromosome is made up of DNA that is tightly wound several times around a protein called histone that supports its structure. When the cell is not dividing, even under the microscope, the chromosomes do not appear in the nucleus. […]

Nucleus: Define its Structure & Function

The nucleus is a membrane-bound organ that contains the genetic material (DNA) of eukaryotes. In this way, it maintains cell integrity by facilitating transcription and replication processes. It is the largest organelle of the cell, accounting for about one-tenth of the entire cell volume. This makes it one of the most easily identified organisms under […]

Cloning: Define its Process and Importance

“The process of producing multiple individuals with similar characteristics through asexual reproduction is called cloning.” or “Production of identical copies of genes of organisms or cells through asexual reproduction.” Cloning: The process of producing identical copies of genes in cells or organisms. Cloning typically occurs in nature, for example, when cells orbit themselves without any […]

Enzymes: Its Structure, and Characteristics

Enzymes are biological catalysts. The main feature of enzymes is that they have biologically active proteins that can accelerate chemical reactions in cells, but they will not alter the reactions. As proteins, they are always bound in chains of amino acids with specific shapes and bonds. or Enzymes can increase the efficiency of biological reactions. […]

Laboratory: Its Apparatus and Uses

Many types of equipment in the laboratory are used for scientific research. However, we have compiled 20 laboratory instruments and all possible general and special lists of their use. They enable us to experiment successfully and make accurate measurements or observations. All common laboratory equipment should be prepared only with the outline diagram and the […]

Bunsen burner: Its Parts and Their Function

Bunsen burner are commonly used in laboratory equipment. It is named by inventor Robert Bunsen. The basic functions of Bunsen burners in the laboratory are heating, sterilizing, and burning. It produces a single open flame. There are six main Bunsen burner parts such as barrel, collar, air hole, air inlet, air valve, and bracket. A […]
