define amphibian ?
Amphibians are four-limbed, ectothermic animals that belong to the class Amphibia. The phylum Lissamphibia includes every extant amphibian. They live in a broad range of habitats, with the majority of species being found in freshwater aquatic, terrestrial, fossorial, or arboreal settings. Therefore, amphibians normally begin their lives as aquatic larvae, but certain species have evolved behavioural adaptations to get around this.
The young typically transition from a larval stage with gills to an adult form with lungs. Some tiny terrestrial salamanders and frogs rely solely on their skin for respiration, whereas amphibians use their skin as a supplementary respiratory surface. Although they resemble lizards on the surface, reptiles, like mammals and birds, are amniotes and do not need bodies of water to survive.

Explanation:
uracil is not because uracil is only RNA.
Answer:
10 H atoms combine with 5 oxygen to form 5 water molecules.
Explanation:
those substances which having low boiling point or low melting point such as water they form covalent bond.
Covalent bonds form between non-metal atoms. Each bond consists of a shared pair of electrons, and is very strong. Simple molecular substances and giant covalent structures have different properties.
Answer:
33.3
Explanation:
Normally there are 4000 to 11000 WBCs in a microliter of blood averaging almost 7500. While there are 150,000 to 350,000 platelets in a microliter blood of a normal person averaging almost 250,000. Thus the ratio can be as 250,000 :7500 resulting in 33.3. If a range is to be given, it ranges from 31.8 to 37.5 per microliter of blood.
