A Petri dish is a flat-lidded dish that is typically 10–11 centimeters (cm) in diameter and 1–1.5 cm high. Petri dishes made out of either plastic or glass are used to hold growth media (Figure 6a). Test tubes are cylindrical plastic or glass tubes with rounded bottoms and open tops...
What is the biology standard for bacteria? What is a general purpose of agar for culturing bacteria in the laboratory? What are the main aspects of microbiology? How are these aspects different from one another? Who is a woman that was very influential in microbiology? List who she was, wh...
The petri dish on the left contains the natural koji mold, whereas the one on the right has been engineered to contain higher levels of a nutrient called ergothioneine and more heme – an iron-based molecule found in many organisms, but is especially abundant in animal tissues, which gives m...
Culture refers to the shared beliefs, practices, and values of a group, while Subculture is a distinct subgroup with beliefs or interests that differ from or coexist with the larger cultural group.
In vitro fertilization (IVF) is a process by which a sperm fertilizes an egg outside a human body, usually in a petri dish (as opposed to an actual test tube). The term in vitro refers to biological processes that occur outside of the normal biological host, often in a laboratory ...

In vitro fertilization or IVF is a widely used assisted reproduction technique that allows couples with infertility problems to achieve pregnancy. It is a technique in which the woman's eggs are extracted by follicular puncture to be fertilized in the la
If we see similar effects in a diverse range of species that span a remarkable amount of time (about a billion years of evolution from the time yeast arrived on the scene to mammals), it increases the chances that what we’re looking at in a petri dish, or cage, is relevant to ...
We all live our lives in different laboratories. Your corner of the world—filled with your experiences, your biology, your environment, your friends, your beliefs—is a different petri dish than mine. There are plenty of fundamentals that apply to all petri dishes, but no matter where you ...
