Answer:
Stem cells are cells in the human body that have the ability to develop into many other body cell types. Stem cells are very useful for drug development, research, they aren't likely to be rejected in transplants, and are used to repair damaged or diseased cells and tissues. However, they cannot be grown for long periods of time, there are very small numbers in each tissue and cell making them very hard to find, and for certain studies they have been shown to cause cancer. To be honest, using them in research does have its pros and cons, they are very useful and easier to use in research, plus they can help repair damaged and diseased cell tissues. But at the same time they can be difficult to use correctly and properly, it can cause serious health problems if cancer doesn't take place. I think that using them in research is okay, as long as they are used correctly and properly.
Hope this helps! :)
Answer:
Phospholipid is the molecules that are amphipathic in nature means the molecule has both hydrophobic as well as hydrophilic regions. The phospholipids are the important constituent of the plasma membrane.
The water and oil gets separate when mix together. If the phospholipid is mixed with the oil and water solution than the oil part is mixed with the hydrophobic part and water will mix with the hydrophilic parts. They can form micelles together.
I think the answer should be B as well hope it helps
