Primary cultures are cell cultures derived from normal animal tissue, tissues are treated with a protease such as trypsin or collagenase to breakdown the extracellualr matrix.
Continous cell lines are tansformed cell lines which have lost normal apoptotic controls and are capable of indefinite growth and culture, they are usullay derived from a cancerous tumor or transformed in culture via a mutation.

What are two examples of continuous cell lines and primary cell lines?
Continuous cell lines include HeLa cells derived from cervical cancer and CHO cells derived from Chinese hamster ovary. Primary cell lines are freshly isolated cells that have not been sub-cultured extensively, such as human primary keratinocytes isolated from skin tissue and primary rat hepatocytes isolated from liver tissue.
What is continuous cell lines?
Continuous cell lines are cells that can be grown indefinitely in culture and have the ability to divide continuously without reaching senescence. They are commonly used in research and industry for studying cell behavior, drug testing, and production of biological molecules. These cell lines are often derived from cancer cells or immortalized normal cells.
Which of these would be a classic continuous spectrum a rainbow the sunlight a neon light fluorescent light or a glowing nebula?
A rainbow would display a classic continuous spectrum because it contains a full range of colors blended seamlessly together, whereas a neon light, fluorescent light, and glowing nebula would exhibit line or emission spectra with distinct lines of color instead of a continuous spread.
What is the difference between endothelium and mesothelium?
Endothelium is a type of epithelium that lines blood vessels and the heart, while mesothelium is a type of epithelium that lines body cavities such as the abdominal and thoracic cavities. Endothelium helps regulate exchange of substances between blood and surrounding tissues, while mesothelium mainly provides a protective barrier and lubrication for organs within body cavities.
Why arent vertical lines allowed in tables on biology reports or journals?
When biology papers first came out on the typewriters continuous vertical lines was not possible. Even though computerized technology has gotten much better, biologists continue to eliminate vertical lines.
What is the difference between finite and continuous cell lines?
Finite cell lines have a limited lifespan and eventually stop dividing, while continuous cell lines are immortal and can divide indefinitely. Continuous cell lines are derived from cancer cells or genetically modified to overcome cellular senescence.
What is the difference between line art and continuous tone?
line art is like clip art. it is art created only with lines. continuous tone art is art that uses a tonal range such as a photograph.
What are two examples of continuous cell lines and primary cell lines?
Continuous cell lines include HeLa cells derived from cervical cancer and CHO cells derived from Chinese hamster ovary. Primary cell lines are freshly isolated cells that have not been sub-cultured extensively, such as human primary keratinocytes isolated from skin tissue and primary rat hepatocytes isolated from liver tissue.
What are continuous lines?
Continuous lines are ones that never seem to end
What is the name for the elevation difference between adjacent and contour lines?
The name for the elevation difference between adjacent contour lines is the contour interval.
What is the difference between interior lines and exterior?
The difference between interior lines and exterior lines are thatInterior lines: Are the lines that are in the inside of the shape or whatever you are trying to find the interior of.Exterior Lines: Are the lines that are outside of the shape or whatever you are trying to find the exterior of.
What is the difference between vertical and horizontal lines?
vertical lines run from top to bottom, horizontal lines run from left to right the difference between the two is 90 degrees if you place vertical lines next to horizontal lines.
What is the time difference between two meridian lines?
The Greenwich Meridian, also known as the prime meridian or International Meridian, bisects the primary division of time zones. Each time zone is 15 degrees of longitude in width, with local variations, and observes a clock time one hour earlier than the zone immediately to the east. The time difference between two meridian lines is one hour (the time difference between two longitudinal lines is 4 minutes and consequently the time difference between 15 longitudinal lines; or two meridian lines; would be one hour). Refer to link below.The Greenwich Meridian bisects the primary division of time zones. Each time zone is 15 degrees of longitude in width, with local variations, and observes a clock time one hour earlier than the zone immediately to the east. The time difference between two meridian lines depends on where you draw the lines. There is no official standard set of lines that everyone is required to use, and a line can be drawn at ANY longitude. Whatever the longitude difference is between the two meridians you decide to consider, the time difference between them (in hours) is nominally 1/15 of that angle.
On a topographic map where would you locate the contour interval in the margin?
It would be the difference between the two darker lines, or index lines, and then divide the space in between with your difference.
What is the difference between slurs and ties in music notation?
In music notation, slurs are curved lines that indicate to play or sing notes smoothly and connected, while ties are lines that connect two notes of the same pitch to indicate they should be played as one continuous note.
What were the difference between the north and south supply lines?
we have textbooks
What tells the difference in elevation between two adjacent lines on a topographic map?
The contour lines on a topographic map represent the difference in elevation between two adjacent lines. The closer together the contour lines are, the steeper the terrain. If the lines are spaced far apart, it indicates a gentle slope. The contour interval, which is typically shown in the map's legend, specifies the difference in elevation between each contour line.
