Question

Explain how human embryonic stem cells, and skin cells taken from the same person would be the same and how they would be different. explain what causes the differences you describe

Answer 1

Embryonic stem cells are pluriponent while adult stem cells are multiponent. This means that embryonic stem cells have more possibilities to what they can be specialized as. This occurs because an embryo isn't fully developed yet, so it's stem cells are less specialized. For example, if you took stem cells from a fertilized egg, those stem cells could be virtually anything because they haven't been "told" what to be yet. Regular skin cells however are already differentiated, meaning they don't have the ability to be anything other than what they already are.

Answer 2

I had this same question in the Unit 3 test and I got 100% for that question. I hope it helps :) if you need a further explanation, I'd be happy to help!

Answer 3

*for that answer

Answer 4

yes pleas can you help me with the question that says
Explain the processes that take place in the stroma including the reactants going in and the products produced from these processes in (a) bright sunlight and in (b) darkness(c) what happens over an extended period of darkness of many days

Answer 5

Sorry.. my grandparents called unexpectedly and I'm not good at multitasking XD

Answer 6

Okay.. time to answer the question :)

Answer 7

First off, photosynthesis 2 is what takes place in the stroma. The light-dependent reactions.

Answer 8

The light-dependent reactions include using light energy from the sun and water (H2O) to create NADPH and ATP with O2 as a by-product. The light-independent (in the stroma) with the addition of carbon dioxide (CO2) to the NADPH and ATP create high energy sugars. With light, this process works smoothly as I described. Without light, the light-dependent reactions won't be able to occur. Because the light-independent reactions feed off of the light-dependent reactions, a prolonged period of darkness would stop both sets of reactions.

Answer 9

( I made a mistake with the first comment. I meant thylakoid XD)
