Answer:
Biosphere
Explanation:
The biosphere is the part of the earth that supports life forms. It includes hydrosphere, atmosphere, and lithosphere. Various ecosystems, aquatic or terrestrial, are present in the biosphere. Biotic and abiotic components of a geographical region that interact with each other together make an ecosystem.
The biotic component of an ecosystem includes all the organisms present in it. Organisms may be unicellular or multicellular. All the organisms are made up of one or more cells. Cells are made up of various biomolecules that interact and enable cells to perform the life processes.
Answer:
Solutions are formed when the water's polar molecules separate the polar molecules of an ionic or molecular compound
Explanation:
Water can hydrogen bond to other molecules due to the O-H bond present in water with partial charges. Water can form hydrogen bonding with other polar molecules. The answer would hence be Solutions are formed when the water's polar molecules separate the polar molecules of an ionic or molecular compound(because polar water dissolves polar molecules in between their interactions).
The correct answer for your question is C.
Answer:
The mechanism is natural selection.
Explanation:
Natural selection is the mechanism that these air-breathing fishes have gone through to survive. This mechanism allows species to survive and reproduce due to differences in the phenotypes of every individual in the specie, throughout the time the heritable traits that every individual inherits changes according to the environment and the characteristics of its ancestors.
