Answer:
Here you go bud A functional adaption is an adaption that helps an organism survive. So, the color and shape of a flounder allows it to camouflage itself among the sea floor to hide itself from predators. Flounders ability to camouflage protects them, so they can survive Hope this helps good luck
Diffusion is a spontaneous process in which molecules move with their concentration gradient. For example, if you place food coloring in water, the food coloring will slowly diffuse through the water until the entire solution has been balanced.
Osmosis is specifically the movement of <em>water</em> through a semipermeable membrane - meaning a membrane that can let some substances in but keep others out - and, similar to diffusion, it moves with its concentration gradient. For example, if you place a glucose solution sealed in plastic in water, water will move into the plastic to even out the concentration of glucose in the entire solution because glucose is too large to diffuse freely.

Pollen grain is odd one among all the other three. Pollen grain in a male gametophytic structure. Whereas all the other three are found inside ovule (nucellus, micropyle and embryo sac).

The structure that are subunits of ribosomes manufactured in the nucleolus, inside the nucleus.
In eukaryotes the ribosomes are produced and assembled in the nucleolus. Here, the ribosomal proteins enters the nucleolus and combines with new four ribosomal RNA strand and create the two ribosomal subunit one is larger subunit 60s and another is smaller subunit 40s.
Then the ribosomes are connected by the 12 molecular bridges and both unit overlap to form 80s ribosome. The assembly of the ribosomes also took place in the nucleolus. Now the ribosomes undergoes the translation, formation of proteins.
