Ответ:
Lampreys resemble eels with regards to their scaleless, elongated bodies. They lack paired fins, and adult lampreys are characterized by a toothed, funnel-like sucking mouth. Of the 38 known extant species, parasitic lamprey species are most well-known. They feed by boring into the flesh of other flesh in order to suck out blood. Adult non-parasitic species do not feed but instead live off on reserves that they have acquired as larvae through filter feeding.

answer:
12 cups of popcorn
step-by-step explanation:
first, find the amount of popcorn 20% constitutes. it is given that the old box holds 15 cups of popcorn.
multiply 15 with 20%. note that:
20% = 20/100 = 0.20
first, multiply 15 with 0.20
15 x 0.20 = 3
now, subtract 3 from the original number:
15 - 3 = 12
the new bags of popcorn holds 12 cups of popcorn.
