During respiration, the energy within the bonds of glucose molecule is released in small amounts in a step-by-step enzyme-controlled reaction.
The correct option from given options is "b", that is <span> it changed ideas about which animals were closely related.
</span>Cladistics<span> was </span>invented for the purpose of improving on taxonomy and it is a way to deal with biological classification. DNA technology lead to more use of cladistics because it changed ideas about which animals were closely related and also it showed new evolutionary relationships between animals.
All other organs, ducts, and glands in the reproductive system are considered secondary, or accessory, reproductive organs. These structures transport and sustain the gametes and nature the developing offspring.
Hope this helps!
Germ-line mutations are mutations that would be passed down to future generations, and recombinations are where the information each parent passes down to the offspring is shuffled.

Only alternate generations would express any genetic variable: False
Body cell mutations would be the only source of heritable genetic variation: False
There would be no new heritable genetic variation possible in the population: True
