The hydrogen and helium in our solar system were created from subatomic particles about years ago. a. 14 billion b. 10.5 billion c. 7.0 billion d. 4.5 billion

The correct answer is: a. 14 billion.

According to Big Bang theory, during the formation of the universe 14 billion years ago, only the hydrogen and helium were formed (with a trace of lithium and beryllium). Other elements were created in nuclear reactions (in huge stellar explosions).

the answer is g1

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
