HEL ASAA how many plant species of the tropical rain forest are identified as having some measure of cancer-fighting ability?

The National Cancer Institute (NCI) has screened approximately 35,000 plant species for potential anticancer activities. Among them, about 3,000 plant species have demonstrated reproducible anticancer activity

it enhances antibody production by t cells of the adaptive immune system.

hope i'm right

explanation:

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
