Answer:D.D.) Suspend the cells in liquid agar culture and monitor which culture continues to grow.
Explanation
Options A-C are correct except D.
→Increase in Telomere length is indicative of abnormal growth, cancer cells can reactive telomerase to increase cell's length.
→Once a monolayer is reached; this a stage of a complete normal cell division , a cell that goes beyond this stage must be mutated. assuming all other factors are constant .
Uncontrolled cell division is an indication of virulent growth in mutated cells.
<u>Cancer cell requires a ,medium of living host to thrive, alga medium will not support growth for carcinoma cells -the correct answer. </u>
<u></u>

: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.)Monitor telomere length over time during multiple cell divisions.
B.) Plate the cells in culture and look for the culture that stops dividing once a monolayer is reached.
C.) Monitor the rate of cell division.
D.) Suspend the cells in liquid agar culture and monitor which culture continues to grow.
<h2>Genetic diversity </h2>
Explanation:
If the environment changes, the species runs the risk of not having the genetic diversity to be adaptable to that change and could go extinct
- Genetic diversity is the diversity or genetic variability within species
- The huge variety of different gene sets defines an individual or a whole population's ability to tolerate stress from any given environmental factor
- While some individuals might be able to tolerate an increased load of pollutants in their environment, others carrying different genes might suffer from infertility or even die under the exact same environmental conditions;the former will continue to live in the environment the latter will either have to leave it or die
- Any change in the environment - natural or human induced causes a selection of events that only the fittest survive
- In case of elephant seals,overhunting reduces the sum of genes available,thus leaving behind a population that is less capable of tolerating any further natural or human disturbances in environment
- The loss of genetic diversity within a species can result in the loss of useful and desirable traits
That would be C. The control group is the group where no variable has been changed for it and it’s how something normally would be.
For example if we’re experimenting the effect of excess water on plant growth the plant getting normal amount of water is the control group and the plant getting excess water is the test group(or groups in most cases there is more than one).
You can use the growth of the control plant as a reference of how the growth of the other plant has been affected(wether it has been increased or decreased or stayed the same)

The ribosome contains enzymes that are associated with protein synthesis.
