The test (independent) variable in this experiment is the color of the water. An independent variable is a variable that can be manipulated or vary in an experimental study to explore its effects. The independent variable is the cause.
Independent variables are the variable which the experimenter changes to test their dependent variable. A switch in the independent variable directly causes a change in the dependent variable. The result on the dependent variable is studied and noted.
There are two main types of independent variables; Experimental independent variables and Subject variables.
The independent variable is the component that can be changed in an experiment.

Ribosomes are small round bodies attached to the endoplasmic reticulum (rough endoplasmic reticulum) in the cytoplasm of cells. They serves as site for protein synthesis due to the presence of ribosomal RNA, rRNA in them.
Thus, cells that are in active protein
synthesis are filled with ribosomes.

Answer:
Invertebrates have a very quick life cycle and die very easily, as a result, they evolve very quickly into many different types of animals. also, they are often very small and their ecosystems are subject to much quicker change than that of vertebrates, meaning that mutations in their genes become relevant more often. Many invertebrates span very large areas (sea animals span most of the oceans, insects span entire continents) and so they evolve to be different species in different places.
Or
They do not have bones, they live on water or land, they can have soft bodies or exoskeletons, and others are parasites.
