Answer: D. Dwarf Planets
Explanation:
Dwarf planets have round shape and orbit the sun. They do not clear their orbits due to smaller gravitational pull and hence, cannot be classified as a planet. A dwarf planet may or may not have moons. Dwarf planets are smaller in size than planets.
Pluto was once classified as planet but was demoted to dwarf planet as many other similar sized objects were found in its neighborhood in Kuiper belt (Eris, Haumea, Makemake) . One dwarf planet is present in asteroid belt as well. It is the largest object in the asteroid belt.

Answer: Sterilization refers to any process that eliminates, removes, kills, or deactivates all forms of life (in particular referring to microorganisms such as fungi, bacteria, viruses, spores, unicellular eukaryotic organisms such as Plasmodium, etc.) and other biological agents like prions present in a specific surface, object or fluid, for example food or biological culture media. Sterilization can be achieved through various means, including heat, chemicals, irradiation, high pressure, and filtration. Sterilization is distinct from disinfection, sanitization, and pasteurization, in that those methods reduce rather than eliminate all forms of life and biological agents present. After sterilization, an object is referred to as being sterile or aseptic.
Explanation:
Answer:
Amphibians lay eggs.
Explanation:
Amphibians include frogs, toads, and salamanders. They are vertebrates, so they have a bony skeleton. Most amphibians live part of their lives underwater and part on land. Amphibians reproduce by laying eggs that do not have a soft skin, not a hard shell. Most females lay eggs in the water and the babies, called larvae or tadpoles, live in the water, using gills to breathe and finding food as fish do. As the tadpoles grow, they develop legs and lungs that allow them to live on land (aka metamorphosis). Even after they change, amphibians still have soft moist skin, and nearly all of them have to live in damp places, so they don't dry out.
