Jaleesa draws a model of a chemical reaction between two substances. She uses a black circle to represent one kind of atom and a white circle to represent another kind of atom. Which model shows that a chemical reaction takes place and that mass is conserved?

b because they naturally adapt to their environment plz mark brainliest

explanation:

while the heads of the phospholipid structure attract water, the tails are hydrophobic. the model shows how the hydrophilic section folds around the fluid molecules to bring them into the cell so they don’t need to pass through the hydrophobic tails.
