A population of insects is sprayed with a new insecticide. Most of the
insects are killed but a few survive. In the next generation, many more of the
insects are unaffected by the insecticide. Which of the following BEST
explains these results?
Answer: This shows that over time, some insects can become "pesticide-resistant" meaning that pesticides don't affect them anymore. And this only happens every few generations. Therefore, each generation is being naturally selected and accumulating variations that make them resist the chemicals. This shows that each cockroach's genes are changing to give them variation from the rest of the population.

why was soil in wheat farms so much more vulnerable to erosion?
Explanation: The potential soil erosion increases if the soil has no or very little vegetative cover of plants/grass and/or crop residues. Plant and residue cover protects the soil from rain impact and splashes from it. It tends to slow down the movement of runoff water and allows excess surface water to infiltrate.

In a multicellular organism, it is cell-to-cell communication that allows the trillions of cells to coordinate activities, including during development and regeneration. The three stages of cellular communication include: reception, transduction, and response. This study determined the key steps of a cell communication pathway involved in salamander limb regeneration. After amputation of a front salamander limb, the severed axons retract within the stump and grow back along the nerve sheath. To elucidate the molecular mechanisms, the researchers set up a series of controlled experiments to determine the events in salamander limb regeneration. Drag the general cell communication steps of the regeneration experiment into the correct order.
The process of amputation will interfere with the ability of cells to communicate with each other.
What is cell to cell communication?The body of whole multicellular organisms have a lot of cells which are differentiated hence they perform diverse functions. The essence of cell differentiation is to allow different cells to perform different functions.
The question is incomplete hence we can not give here the process of cell regeneration. However, we know that the process of amputation will interfere with the ability of cells to communicate with each other.

Why doesn't a gummy bear grow as much in sugar water as it does in normal water?
Answer:
In comparison to the gelatin molecules in the candy, salt or sugar ions in water are significantly smaller. Water molecules go to a location with more solute to balance things out due to osmosis. The problem is that the water is trapped inside the candy and cannot escape. Because the Gummy Bear can't get any smaller, it keeps the same size.
