Biology is the branch of science that primarily deals with the structure, function, growth, evolution, and distribution of organisms. It’s a methodological study of life and living things.
Biology is the scientific study of life. It spans multiple levels, from biomolecules and cells to organisms and populations12. All living things share common biological phenomena, such as reproduction, cell division, and the transmission of genetic material.
What is Botulism ? A toxin generated by the bacterium Clostridium botulinum causes the uncommon but deadly disease known as botulism. This toxin causes paralysis by interfering with the neurological system. It is One dangerous and sometimes fatal illness. See a doctor right away if you think you or someone you know may have it. […]

Binary Fission Certain protists and bacteria that are single-celled creatures use asexual reproduction called binary fission. One parent cell divides into two identical daughter cells; it is a simple process. Single-celled organisms such as bacteria and certain protists use an asexual reproduction mechanism called B. fission. The division of a single parent cell into two identical daughter cells is a straightforward procedure. Steps of B. Fission DNA Replication The genetic material is duplicated twice, exactly by the circular DNA molecule. Cell Division As new components for the cell wall and plasma membrane are created, the cell grows. DNA Division The two DNA molecules adhere to the cell membrane in distinct places.

Brucella Agar The purpose of Brucella agar is to isolate and identify the bacteria that cause brucellosis, a zoonotic illness that affects both humans and animals. It is a selective and differential culture medium. Brucella Blood Agar (BRU) is designed to isolate, quantify, and partially identify clinical specimen-derived obligate anaerobic bacteria. If properly incubated, this

Blood group, or blood type, is the classification of blood based on the presence or absence of particular antigens on the surface of red blood cells. These antigens determine compatibility for blood transfusions and play an important role in immunological responses. What is Blood Group? A blood group, also known as a blood type, is

Blastocyst stage is an important step in the early development of animals, including humans. It occurs after fertilization but before implantation into the uterine wall. It is essential for embryo and placental development after implantation into the uterine wall. What is Blastocyst? It is an early stage in the development of mammalian embryos, including humans,
What is Biuret test for protein? Biuret Test for Proteins are made up of fundamental building blocks called peptide bonds, which can be found using the straightforward and accurate Biuret test. It takes its name from the chemical biuret, which exhibits a corresponding color change. The peptide bonds that bind amino acids together to make proteins can be found using a chemical test called the Biuret test. It is a widely used, rather easy test in analytical and biochemistry. Principle of Biuret Test for protein The Biuret

Bone vs cartilage are two different kinds of connective tissue—bone and cartilage—each having special qualities and purposes. Cartilage is flexible and resilient, providing cushioning and shock absorption, whereas bone is hard and solid, providing structural support. What is a Bone ? In most vertebrate animals, a bone is a hard organ that is a part of the skeleton. In addition to producing red and white blood cells, storing minerals, giving the body structure and support, and allowing mobility, bones also safeguard the body’s other organs. The
