WILL MARK BRAINLIEST Ella puts a few drops of food dye into a beaker full of water. After letting it sit for 20 minutes she notices all the water has turned that color. This is an example of , which is a passive transport process. (hint: there is no semipermeable membrane to pass through) *

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)

the answer is learned

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
