In the previous article we learned about cell structure and functions. Now in this article we will learn about Prokaryotic and eukaryotic cells. Introduction Hey, if I told you, that you are surrounded by 100 trillion bacterial cells, would you believe? Yes, If you look closer than you will find trillions of bacterial cells on … Read more
A cell is like the tiny building block that makes up all living things, from plants and animals to bacteria. Imagine it as a microscopic bag filled with stuff that keeps life going. Every cell has a thin outer layer called a membrane, which holds everything inside and controls what goes in or out. Inside, … Read more
Principles Of Biotechnology Biotechnology has grown and changed a lot over the years. The old way of doing it was to use microbes to make products that people could use. Now, the new way is to use genes to make vaccines. So, the European Federation of Biotechnology (EFB) has come up with a new definition … Read more
Biosafety guidelines provide guidelines, policies, and procedures that must be observed by all personnel who work in facilities handling microbiological agents, such as bacteria, viruses and parasites, fungi and prions. These guidelines are required for all institutions, including clinical and microbiological labs, biomedical research laboratories, teaching and training laboratories, and other healthcare institutions (e.g. hospitals, … Read more
What is Biosafety Cabinet? A biosafety cabinet (BSC), also known as a biological safety cabinet or microbiological safety cabinet, is a specialized laboratory workspace designed to handle materials contaminated with or potentially contaminated with pathogens requiring a specific biosafety level. The primary purpose of a biosafety cabinet is to provide a safe working environment for … Read more
Definition of Simple columnar epithelium The simple columnar epithelium, which is one type of epithelium, is made up of a single layer consisting of long, elongated cells. These cells are located in areas where absorption or secretion are the primary functions. The cells of the columnar epithelium can also be modified, just like cuboidal epithelium. … Read more
Definition of p-value The p-value, or estimated probability represents the most reliable probability of providing the lowest amount of significance, that the null hypothesis isn’t the case. Formula of p-value How to find p-value? P-values can be determined through comparing test results against the table of p-values for various scores. The scores calculated by the … Read more
What is Stratified cuboidal epithelium? Definition of Stratified cuboidal epithelium Stratified cuboidal epithelium is a type of epithelial tissue characterized by multiple layers of cells, with the surface layer consisting of cube-shaped cells. It is primarily found in glandular structures and plays roles in protection, selective absorption, and secretion. Stratified cuboidal epithelium labeled Stratified cuboidal … Read more
Definition Glandular epithelium The glandular epithelium comprises a set of tissues that is not the epithelium that covers and lines that is specifically designed to secrete and produce of different macromolecules. Due to its primary role it is often referred to as”the secretory epithelium. It is situated under the lining and covering epithelium. It may … Read more
What is hypotonic solution? Definition of Hypotonic solution A hypotonic solution is one that has a lower solute concentration compared to another solution, leading to a net movement of water into the region of higher solute concentration, typically across a semipermeable membrane. What Happens to Cells when it is placed in a hypotonic Solution? When … Read more
