This diagram seems to begin with Multicellularity. So, as you follow the line, the next is tissues, then three-germ layers, bilateral symmetry
So, right before 3 germ layers is tissues
So, the answer is D
The answer should be D, water; reach equilibrium.
Osmosis is only the movement of water, down the water potential gradient. Movement of other substances should be involved in diffusion or active transport instead.
The goal of osmosis (also diffusion) is to make the concentration of substance (water potential for osmosis) the same. This is the meaning of equilibrium. Water molecules won't stop moving after equilibrium is reached, but there no net flow, meaning the amount of water molecules flowing from the left to right for example is same as the molecules flowing from right to left. So, the second answer is to reach equilibrium.
The answer is D.
are there answers your supposed to choose from?
The products that are derived from invertebrates are the following:
1. food - crabs, lobsters, oysters, octopuses: all of these are invertebrates (meaning they have no spine) and are used as food
2. shell - seashells are invertebrates and their shells are used for various purposes
