Which of the following describes the structure formed when a probe hybridizes to a gene?

A. A double-stranded DNA structure in which one strand is the probe.

B. A double-stranded DNA structure in which different genes are
linked together.

C. A single-stranded structure consisting of labeled DNA from the
probe.

D. A single-stranded structure consisting of unlabeled DNA from the
gene.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.

genetic variation will increase because of a new habitat and food source.
