PLSSSA HELPPP Why does the author include this paragraph in the article?
А- to emphasize the urgent threats to biodiversity
on Earth
B- to illustrate that humans are able to create
solutions to the threats to biodiversity
С-to contrast the rate of die-off happening to
certain modern species with that of the
dinosaurs
D- to demonstrate the effects of the loss of
biodiversity on historical ecoystems

This problem has been solved! see the answeryou are investigating two traits in fruit flies controlled by one gene each. the b gene controls for body color (black or brown), while the r gene controls for body sculpture (rugose or smooth). after crossing rugose black flies with smooth brown flies, you obtain an f1 generation of 100% smooth black flies.what are the dominant alleles? (1 pt)what are the genotypes of the two parent flies to perform a dihybrid test cross? (1 pt)after running a dihybrid test cross, you find 1000 offspring with the following phenotypes: , rugose406black, smooth86brown, rugose94brown, smooth4141000fill in the expected column with the expected number of offspring in each class of phenotypes. (1 pt)what phenotype classes represent the recombinant offspring? (1 pt each)calculate the relative genetic distance between the body color gene and the body sculpting gene (show your work). (1 pt).
