2 Points
Sometimes engineers increase output through crossbreeding. This is when
they
O
A. cultivate a variety of plants in one area so that cross
contamination does not occur.
B. combine two plants so that each plant's strength compensates for
the other's weakness.
O
C. cultivate a variety of plants in one area so that one pest does not
destroy all the crops.
O
D. genetically alter the DNA of a plant to produce a desired trait.

The two naturally occurring isotopes of chlorine are 35cl (34.969 amu, 75.77%) and 37cl (36.966 amu, 24.23%). the two naturally occurring isotopes of bromine are 79br (78.918 rm amu, 50.69%) and 81br (80.916 amu, 49.31%). chlorine and bromine combine to form bromine monochloride, brcl. 1. how many peaks will be present in a mass spectrum for brcl? the four combinations of molecule possible given these four isotopes are: 81br37cl, 81br35cl, 79br37cl, and 79br35cl. 2. what are the masses of the four different brcl molecules? express the masses using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.
