The answer is the cerebrum. It is sometimes called the telencephalon,
is the biggest and most extremely advanced part of the human brain. It covers
about two-thirds of the brain form and lies over and from place to place most
of the structures of the brain. The cerebrum is separated into right and left
hemispheres that are joined by the corpus callosum.
Explanation:
This experiment was conducted to investigate the selective permeability of dialysis tubing. The permeability of the tubing to glucose, starch, and iodine (potassium iodide) was tested. The dialysis tubing was clipped to form a bag so that glucose and starch were fed into the bag through the other end, and was also clipped to avoid the seeping of the solution.
I think you forgot to give the options along with the question. i am answering the question based on my knowledge and research. "One group of bears was less highly evolved less than the two other groups and was destined to die out" is the one that explains why only one group of bears were extinct. I hope the answer has helped you.
Under the leaf, but a microscope must be used.
Hope this helps!
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.
