. Explain how Verchow’s cell theory (every cell comes from a previously existing cell), coupled with his idea that cells are the basis of health or disease, lead to the development of a major cancer treatment strategy. 2. What are the limitations of this single strategy, and what was the effect of “pushing to the limit“ on the patient? 3. Why did most physicians of the time think that cancer could not be treated with a chemical? 4. What lead...

ANSWER 1: 1.56*10^7, ANSWER 2: 1.579*10^-10, NEED 3 & 4
A red blood cell typically carries an excess charge of about -2.5 times 10-12 C distributed uniformly over its surface. The red blood cells can be modeled as spheres approximately 7.0 mu m in diameter and with a mass of 9.0 times 10-14 kg. How many excess electrons does a typical red blood cell have? Does the mass of the extra electrons appreciably affect the mass of the cell?...

State rational for your answer: 6) In unstimulated muscle cells, the glucose transporter Glut4 is present in the membrane of endosomes. Upon stimulation of these cells with insulin, the endosomes fuse with the plasma membrane, thereby depositing Glut4 in the plasma membrane, where it serves to transport glucose into the cells. In order for insulin to elicit this change in Glut4 localization, insulin...

Please explain the steps
How fast would two nuclei have to move so that in a head-on collision they would get close enough to fuse? (Treat the nuclei as point charges, and assume that a separation of 1.0 × 10-15 m is required for fusion.) Express your answer using two significant figures. Constants If two deuterium nuclei (charge +e, mass 3.34 x 10-27kg) get close enough together, the attraction of the strong nuclear force will fuse them to make an...
