- The unified cell theory proposed in the 1830's states that ?Hello, In the provided picture I am to select the FIVE compunds that would be the most stable in a CELL MEMBRANE. I had selected A,B,C,D,and E and recieved 1.2 out of 2. Can you please help!!! Thank you so MuchConsider the 5 tasks necessary for cell survival that you learned about in Activity 2.

- Mitosis occurs daily in a human being. What type of cells do humans need to produce in large quantities on a daily basis?Calculate the number of cells in the body of an average 68-kg (150-lb) adult. (This will only be accurate to about 1 part in 10 but should give you an idea how scientists estimate this commonly quoted number.) Assume all cells are spheres 20 m in diameter. The volume of a sphere can be determined by the equation v=4/33. (Hint: We know that about two thirds of the water in the body is intracellular and the density of cells is nearly 1 g/mL. The proportion of the mass made up of water is about 60%.)Briefly Mentionabout the important functions of apoptosis & autophagy.
