Imagine that you are a graduate student working in a cancer lab. You accidentally mix unlabeled tubes of carcinoma cells with tu
bes of normal epithelial cells. Which of the following is NOT a possible strategy to allow you to distinguish which tubes contain carcinoma cells? a. Plate the cells in culture and look for the culture that stops dividing once a monolayer is reached. b. Suspend the cells in liquid agar culture and monitor which culture continues to grow. c. Monitor the rate of cell division. d. Monitor telomere length over time during multiple cell divisions.
Cancer is a disease caused by the uncontrolled division of the cell. Certain carcinogens cause the mutation in the DNA of the cells in response to which the normal cells divide continuously without differentiation which leads to the growth of the mass = of undivided cells.
In the given question, when student placed the cancer cells with normal cells than the cancer cells after few days will form a mass of undivided cells which is the result of the continuous cell division without differentiation not observed in the normal cells.
There are guard cells surrounding each stoma that cause them to open or close throughout the life cycle of the plant. This occurs in response to water and ions concentration in the plant cell.
Explanation: oxygen poor blood from the right ventricle into the lungs, where the oxygen enters the bloodstream. The pulmonary veins bring oxygen rich blood to the left atrium.
The moon has phases because of where the sun shines on it. Only yhe part wiyh light of the moon is visible. As the moon moves, the sun light hits is at different angles and creates the different shapes we call phases.
