Animal Diversity
Nematodes are commonly known as roundworms. They are free-living, very tiny organisms. They have an elongated and tubular body. These organisms have a nervous system and are mostly act as parasites to both animals and plants.
Platyhelminthes
Platyhelminthes are also known as "flatworms" because as they are dorsoventrally flattened from head to tail. They are invertebrate, soft-bodied, acoelomate, unsegmented and have bilateral symmetry.
Concisely explain the graphs below showing different patterns of adaptations of animals to their environment.

This process is called the Bradford Assay; it is a colorimetric assay. A special reagent turns blue when it binds to amino acids present in protein. The intensity of the color is best measured with a spectrophotometer (a device for comparing two light radiations, wavelength by wavelength). In the case of the Bradford Assay the greater the absorbance, the higher the protein concentration. A series of tests were performed on some samples and spectrophotometer: following measurements were obtained using a Protein Concentration (mg/ml) Absorbance (A) 0.26 0.098 0.56 0.213 0.383 0.84 1.12 0.473 1.40 0.527 TASKS: 1.
