Osmosis is the diffusion of water. Water tends to diffuse to the area with a higher concentration of solute. (Particles) In this case, Im assuming the fertilizer is the solute because it contains chemicals. Therefore, since water tends to diffuse to higher concentration of solute, the water in the grass will diffuse out to dilute the fertilizer on the surface of the grass. Without water, the grass will be dehydrated and shrivel up and die. Hopefully you find my answer helpful!
If you have both parents with long ears and some of the offsprings have short ears, you can say both parents are heterozygous for this. Both have a dominant (long ear), and a recessive allele (short ear).
To prove this, you can draw a Punnett square, and you'll see the probabilities of the offsprings.

They lived for a fairly short period of time. An index fossil allows a scientist to determine the age of the rock it is in. Hope that this helps you :)
