Viable cells will take up the dye by active transport and
incorporate the dye into lysosomes, whereas non-viable
cells will not take up the dye. After the cells have been
allowed to incorporate the dye they are briefly washed
or fixed. The incorporated dye is then liberated from the
cells in an acidified ethanol solution. An increase or
decrease in the number of cells or their physiological
state results in a concomitant change in the amount of
dye incorporated by the cells in the culture. This
indicates the degree of cytotoxicity caused by the test
material.

Why does the red blood cell lyse in an isosmotic solution of urea?
Urea is isosmotic to the intracellular fluid of red blood cells, but because the membranes of the blood cells are permeable to urea. Urea enters the cell at a much more rapid rate than other permeable solutes (because of the steep concentration gradient) and the cell fills to it bursts.
Trace the path of a red blood cell from the lungs to the aorta?
Trace a drop of blood from the left knee to the right arm
Which is the Hot wire and which is the Neutral wire if the wires you see are a Black a Red and a Yellow wire?
Black red and yellow is three-phase. there is no neutral.
What color is phenol red at neutral pH?
it becomes an orange-red color
What does Babesia microti do?
Babesia microti is a tick-borne parasite that infects and destroys red blood cells in humans. It causes babesiosis, a disease characterized by symptoms such as fever, fatigue, muscle aches, and anemia. In severe cases, it can lead to complications like organ failure.
If the mitochondrion is fundmental to the mtt assay which organelle plays a key role in the neutral red viability assay and why?
lysosome
How oxygen enters a red blood cell from alveoli in the lungs?
Diffusion along the (partial) pressure gradient.

Why chloroform is used in the assay of potassium iodide?
Chloroform displace iodine from KI and the solution become red.
When oxygen enters the blood it combines with the red blood cells and forms what?
Oxygen enters the blood stream via the erythrocyte (Red blood cell, RBC), I am not sure what you are asking but the hemoglobin inside the RBC has 4 "oxygen holder molecules" called Heme's where an iron molecule (Fe++) is stored, the Fe++ is what oxygen attaches to.
Trace the path of a red blood cell from the lungs to the aorta?
Trace a drop of blood from the left knee to the right arm
Which is larger the egg cell or the sperm cell?
Egg cells are the biggest: you could only fit one on the head of a pin. But I'm not sure if a sperm cell is bigger than a red blood cell or vice versa.
Bloodcells that carry oxygen?
red blood cells carry oxygen. That would be red blood cells. Haemoglobin. Due to the haem component of the cell. It attracts and binds oxygen to carry it around the body. When it meets a cell, for example a muscle cell, lacking in oxygen the oxygen unbinds from the red blood cell and enters the muscle cell. Well that's it simply. You can get some pretty good diagrams of structure from various ite on the web. It may be worth while having a look at those.
Is red indicator neutral?
Yes.
What is the name of the normal protein and a red blood cell?
and a red blood cell or in a red blood cell? if its in a red blood cell i would say haemoglobin
When is a red blood cell red?
a red blood cell is red when it reaches oxegen.
What is a Red cell carrier?
