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.
Answer:
It is B all the other answers are for other types of injuries, knee scrapes don’t swell, it might divide, and it would produce more protein
Explanation:
Tim scraped his knee during a fall, and it needs to be repaired, so the growth factors are packaged into a vesicle and secreted from a cell that acts upon target cells all nearby cells. The cells start dividing, which is present in Option A.
What happens during cell repair?When the cell breaks, then the nearby cells release the paracrine signaling that goes to the cells and stimulates the cells to make the mitosis process and divide, which includes DNA replication, protein synthesis, and RNA synthesis, and then from the original cells, the daughter cells are formed and fill the gap that is formed in the injury and the far cells don't get the signal as the paracrine factors acts nearby.
Hence, Tim scraped his knee during a fall, and it needs to be repaired, so the growth factors are packaged into a vesicle and secreted from a cell that acts upon all nearby cells. The cells start dividing, which is present in Option A.

This tall, branching saguaro cactus provides nesting sites, food, and water
to other animals of the Sonoran Desert.
Which term best characterizes the role of the saguaro cactus in its desert
ecosystem?
The term biotic factor best characterizes the role of the saguaro cactus in its desert ecosystem.
What is an Ecosystem?An ecosystem may be defined as a place or an area where members of different species live together and interact with one another for the purpose of food, space, and shelter.
Saguaro cactus provides nesting sites (space), food, and water to other animals of the Sonoran Desert and allows them to survive and reproduce in a much better way. This refers to the biotic factor of an ecosystem.
Therefore, the term biotic factor best characterizes the role of the saguaro cactus in its desert ecosystem.

The Galapagos Islands contain 15 species of finches that mainly have different beak types and sizes. These finches evolved from a common ancestor that moved to these islands and occupied different parts of it.
What was the most likely reason these finches evolved into different species?
A. They interbred with other bird species.
B. They adapted to different food sources.
C. The beaks provided a variation for survival in extreme climates.
D. The beaks prevented them from being seen by predators
Answer:
The breaks provided a variation for survival in extreme climates.
Explanation:
The most likely reason these finches evolved into different species is the beaks provided a variation for survival in extreme climates.
What do you mean by Species?Species may be defined as a group of organisms that can reproduce naturally with one another and create fertile offspring.
The finches evolved to have different beak shapes because they adapted to different food sources. But when these variations are passed on to the next 10 to 12 generations, reproduction isolation has been observed. From here it can be said that a new species have been evolved.
Therefore, the most likely reason these finches evolved into different species is the beaks provided a variation for survival in extreme climates.

in wetter climates plants usually have more stomata and grow faster. Suggest why
Answer:
A wetter climate slows the rate of transpiration allowing for there to be more stomata present on each leaf. Plants lose a lot of water when they open their stomata to get carbon dioxide for photosynthesis, especially in hot, dry deserts. Cacti lose less water by only opening their stomata at night.
