how many grams of nitrogen -16 will br left from a 16g sample after 21.6 seconds if its half life is 7.2 seconds

From Radioactivity

N/N° = (1/2)^t/t•

Where

N=Remaining Mass

N°=Initial Mass

t=Time of decay Or Time spent on decayingb

t•=Half life

N=N°(1/2)^t/t•

N=16(1/2)^21.6/7.2

N=16(1/2)³

N=16(1/8)

N=2g.

Have a great day✌✅

prokaryotic cells do not have a nucleus in which the dna is stored in, it floats freely inside the cell.

eukaryote cells do have a nucleus in which the dna is stored in.

a

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
