It is much easier to extract DNA from the softer cellular structures of the inner cheek than the tougher exterior skin layers.
With smaller cells, there is a greater surface area.
no answer :I srry
they both are cells
No, you cannot determine a person's blood type from a urine sample. Blood type is determined by antigens on the surface of red blood cells, which are not present in urine. To determine blood type, a blood sample is needed for testing.
In humans, squamous cells are found in the epidermis of the skin, in the lining of hollow organs and in the respiratory and digestive tracts. Squamous cells in urine may indicate contamination due to the presence of bacteria.
Question doesn't make sense. You can be group B and rh + or group B and rh -. The B antigen and the D antigen (which causes you to be rh+ or lack of makes you rh-) are seperate things stuck to the surface of red blood cells.
What about: "The doctors had to do a biopsy on their patient so they could find out the problem in her leg." or more specifically: "After doing a biopsy through a small incision in her leg, her doctors checked the tissue sample for cancerous cells."
Doctors harvested cells from Henrietta Lacks by taking a small tissue sample from her cervix without her consent during a medical procedure. The cells were then cultured in a laboratory setting by providing them with the necessary nutrients and environment to multiply and grow continuously, becoming the famous HeLa cell line.
The answer is small intestine.
NSS (normal saline solution) is used instead of water in preparing a fecal smear to prevent lysis (rupturing) of red blood cells in the sample. Using water can cause hemolysis, which may interfere with the accurate interpretation of the fecal sample. Normal saline is isotonic and helps maintain the integrity of the red blood cells in the smear.
You are probably thinking of the surface area to volume ratio. When you have two small cells instead of one big one, there is more 'outside'.
Cells are typically placed on a glass slide before being viewed under a microscope. The glass slide provides a stable and transparent surface for the cells to be observed. A cover slip is often placed on top of the cells to protect them and to help focus the microscope's lenses on the sample.
