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?
O The growth factors are packaged into a vesicle and secreted from a cell that acts upon all nearby cells. The cells
start dividing
O 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.
O 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.
O 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.

Sea levels are rising due to climate change while increasing numbers of people are moving into coastal areas. to accommodate more people, there has been increased construction of beachfront resorts and condominiums. how is this impacting sea turtle numbers and biodiversity and why? a. the increased human population in coastal areas has meant that more food is available to the turtles (e.g., dropped food, waste from restaurants), which has led to an increase in the numbers and diversity of sea turtles. b. there has been very little change in the numbers and biodiversity of sea turtles because the planet is so vast that they can simply relocate to less crowded beaches. c. this has resulted in a decrease in numbers and diversity of sea turtles because it is restricting available nesting sites, and hence reproduction. d. this has resulted in an increase in numbers and diversity of sea turtles because people are around to protect them from natural predators.
