Tim scraped his knee during a fall and it needs to be repaired. The closest skin cells begin sending out growth factors through paracrine signaling to tell all nearby skin cells to start replicating to repair the damaged area. What are the next steps once the message is sent?
A) The growth factors are packaged into a vesicle and secreted from a cell that acts upon all nearby cells. The cells start dividing.
B) The growth factors are packaged into a vesicle and secreted from a cell that acts upon target cells near and far. The cells start mitosis.
C) The growth factors are packaged into a vesicle and secreted from a cell that acts upon only a target nearby cell. The cell starts swelling up.
D) The growth factors are packaged into a vesicle and embedded into the plasma membrane where it is detected by other cells. The cells produce more proteins.

In eukaryotes, genetic information is passed to the next generation by processes that include mitosis or meiosis. which of the explanations identifies the correct process and supports the claim that heritable information is passed from one generation to another? a. mitosis, followed by cytokinesis, produces daughter cells that are genetically different from the parent cell, thus insuring variation within the population. b. during mitosis, dna replication occurs twice within the cell cycle to insure a full set of chromosomes within each of the daughter cells produced. c. in asexual reproduction, a single individual is the sole parent and passes copies of its genes to its offspring without the fusion of gametes. d. single-celled organisms can fuse their cells, reproducing asexually through mitosis to form new cells that are not identical to the parent cell.
