Imagine that you are a graduate student working in a cancer lab. you accidentally mix unlabeled tubes of carcinoma cells with tubes 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.

The correct answer will be option-C

Explanation:

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.

Thus, Option-C is the correct answer.

option a is correct i.e.

explanation:

in context to the membrane of nerve impulse, the outer membrane of neuron is semi permeable that is only sodium ions can pass through the membrane i.e. smaller ions can pass through the membrane while larger ions cannot pass through it.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
