Blood transfusion is the process of transferring blood products into a person's circulation intravenously. [ 1] Transfusions are used for various medical conditions to replace lost components of the blood. Early transfusions used whole blood, but modern medical practice commonly uses only components of the blood, such as red blood cells, plasma ...
This process of the second bacterial cell taking up new genetic material is called transformation. In molecular biology and genetics, transformation is the genetic alteration of a cell resulting from the direct uptake and incorporation of exogenous genetic material from its surroundings through the cell membrane (s).
Paper marbling is a method of aqueous surface design, which can produce patterns similar to smooth marble or other kinds of stone. [ 1] The patterns are the result of color floated on either plain water or a viscous solution known as size, and then carefully transferred to an absorbent surface, such as paper or fabric.
The history of science is often seen as a linear story of progress [27] but historians have come to see the story as more complex. [28] [29] [30] Alfred Edward Taylor has characterised lean periods in the advance of scientific discovery as "periodical bankruptcies of science". [31] Science is a human activity, and scientific contributions have ...
An inoculation needle is a laboratory equipment used in the field of microbiology to transfer and inoculate living microorganisms. [1] [full citation needed] It is one of the most commonly implicated biological laboratory tools and can be disposable or re-usable. [1] A standard reusable inoculation needle is made from nichrome or platinum wire ...

Bacterial conjugation is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells. [ 1] This takes place through a pilus. [ 2][full citation needed] It is a parasexual mode of reproduction in bacteria. A micrograph displaying Escherichia coli undergoing bacterial ...
