<span>The correct answer to this question is C - an autotroph is an organism that has to produce it's own food rather than finding sources of food elsewhere, so an example of this might be a primary producer. Plants and certain types of bacteria are all autotrophic.</span>
Experiment that tests the effects of changing salt concentrations on regeneration of brain cells in Alzheimer’s patients.
Explanation:
Experiments are conducted on brain cells by first growing human embryonic stem cells in a Petri dish and then converting them to brain cells. later the Alzheimer’s disease was genetically engineered into those nerve cells through gene mutation.
When these cells are exposed to varying concentrations of salt solution, the cells with shrink or swell according to the concentration due to cellular osmosis.
The cells will undergo chemical changes due to this. The regeneration probabilities of nerve cells affected by Alzheimer’s disease can be studied by such experiments.
Answer:
At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes.
