Earthquakes occur all the time all over the world, both along plate edges and along faults. Most earthquakes occur along the edge of the oceanic and continental plates. The earth's crust (the outer layer of the planet) is made up of several pieces, called plates.
Taxonomy used to have two groups of vertebrates and invertebrates. But invertebrates are far more diverse when it comes to the phylogenetic tree. Vertebrates all share same characteristic which is a back bone made of vertebrae, but invertebrates don’t share a common anatomical structure that all have; they are radically different in structure so they can’t be grouped in a single group. You have Arthropoda, which all have jointed limbs and segmented bodies and molt their cuticles. There’s Cnidaria, which most have tentacles and nematocysts and are radially symmetrical. And Mollusca, which have a muscular foot and a part of their body called a mantle. All these groups are invertebrates, but there’s nothing they share in common WITHOUT referring to the fact that they don’t have vertebrae. So basically that’s just an example why they can’t be grouped into one category; they all have different characteristics and are placed in different areas of the animal kingdom’s phylogenetic tree.

Answer: a. adaptation
Explanation:
Sensory adaptation can be define as the reduction in sensitivity to a stimulus after a constant exposure to the stimulus. When the awareness and sensitivity towards the constant stimulus reduces, then the attention of the receives diverts to another stimulus present in the environment around it.
The given situation demonstrates the sensory adaptation this is because of the fact that Sariah developed the sensory adaptation towards the constant stimulus that is chirping. Now her attention diverts and she was able to talk to her friends, and she lost awareness of chirping although it was still there.
A microorganism (or microbe) is any microscopic living organism or virus, that is too small to see with the unaided human eye without magnification. Microorganisms are very diverse. They can be single-celled or multicellular and include bacteria, archaea, viruses and most protozoa, as well as some fungi, algae, and animals, such as rotifers and copepods. Many macroscopic animals and plants have microscopic juvenile stages. Some microbiologists also classify biologically active entities such as viruses and viroids as microorganisms, but others consider these as non-living.
