answer : the mass of the helium in the blimp is, 1.1216 kg
solution : given,
volume of helium in the blimp =
density of helium in the blimp =
formula used :
now put all the given values in this formula, we get the mass of helium in the blimp.
therefore, the mass of the helium in the blimp is, 1.1216 kg
create and use more electricity then previously used before. a lot of power is created by burning fossil fuels, the burning of them will be increased so more is needed to give power to everyone.
initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ''read'' the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.
i think the answer is b. they have low reactivity.hope this (:
