Cellular structures shared by all eukaryotes and prokaryotes include which of the following?
choose one or more:
a. cell wall
b. chloroplasts
c. ribosomes
e. cytoplasm
f. cell membrane
g. flagella

Ribosomes, cytoplasm and cell membrane.

Explanation:

Prokaryotic organism does not contain well defined nucleus and lacks the membrane bound cell organelle. Eukaryotic organism has well defined nucleus and membrane bound cell organelles are present.

Despite many difference, all prokaryotes and eukaryotes share some common characters. The ribosomes are present in both prokaryotes and eukaryotes. Cell emmebrane and cytoplasm are also common that are present in all eukaryotes and prokaryotes.

Thus, the correct answer is option (C), (E) and (F).

advantage of using stem cells in medical research:

1.       it provides medical benefits in the fields of therapeutic cloning and regenerative medicine.

2. it provides great potential for discovering treatments and cures to a variety of diseases including parkinson disease, spinal cord injuries, diabetes, alzheimer’s disease and many more.

3. limbs and organ could be grown in lab from stem cells and then used in transplant or treat illness.
