For each of the examples, simple diffusion, carrier, and channel mediated, each type involves the flow down a concentration gradient. This means that the molecules flow from an area of high concentration to an area of low concentration. In turn, this allows for a passive process, meaning no ATP is needed! I hope this explains your question.
Answer and explanation;
-Stem cells, Adult stem cells and skin cells , have a similarities and they may also differ in a number of ways.
-A stem cell has not gone through the process of differentiation, so they have the potential to become any type of cell.
-Adult skin cells have gone through differentiation and cannot become another type of cell. Same case applies to the skin cells, they have already undergone differentiation;
-Similarity; The cells that are taken from the same person would have the same DNA.
-Difference; The skin cells and the adult stem cells have already gone through differentiation, whereas embryonic stem cells have not. The different genes that the types of cells have are turned on and off causing the differences.
I'm fairly sure the answer is C.
There are different types of pathogens, but we're going to focus on the four most common types: viruses, bacteria, fungi, and parasites. (:
Answer:
C. mitosis
Explanation:
Mitosis is one of the two types of cell divisions in which a single cell divides into two genetically identical daughter cells. Mitosis is used for growth and repair of tissues in living organisms.
Mitosis is also the process by which cells multiply/duplicate themselves. Hence, the process of a cell increasing its size, doubling its genetic contents, dividing into two independent cell, and repeating the process over and over again is called MITOSIS.
