Answer:
Phanerozoic Eon is divided into three eras on the basis of prevailing climatic conditions on earth and dominant life forms present during the time.
Explanation:
The Phanerozoic Eon is divided into three eras namely the Paleozoic, the Mesozoic, and the Cenozoic era. The basis for classification of the Phanerozoic eon into three eras are the prevailing climatic conditions on earth and dominant life forms present during the time. Changes in climatic conditions of earth altered the species composition and dominant life forms present in each era.
Answer:

igneous rocks are the rocks which are formed by the cooling of molten magma cooling can be on the surface or below the earth surface.
sedimentary surface is the rocks which are formed by the weathering or some chemical action upon the rock due to the passage of time.
metamorphic rocks are those rocks which are formed due to the high pressure and temperature acted on the rocks.
so, the best answer will be sedimentary rock
hence, the correct answer is option B

The reaction that was catalyzed by amylase is hydrolysis.
The answer is; B

Genetic shuffling in sexual reproduction, also called gene recombination occurs during meiosis and also when different organisms exchange genetic material such as in bacteria.
