,1. A student is observing a cell under the microscope. It is observed to have
nm nm nm nm nm nm nm nm nm nm nm nm nm
supercoiled DNAwith histones. Which of the following would also be observed by
nm nm nm nm nm nm nm nm nm nm nm nm nm
the student? a. A single circular chromosome
nm nm nm nm nm nm nm
b. A nucleus nm
c. Free-floating nuclear material nm nm
d. No organelles nm
ANS: B nm
The cell described is a eukaryotic cell, so it has histones and a supercoiled DNA within
nm nm nm nm nm nm nm nm nm nm nm nm nm nm nm
its nucleus; thus, the nucleus should be observed. A single circular chromosome called

neighboring alphacells. This action is an example of which of the following signaling
nm nm nm nm nm nm nm nm nm nm nm nm nm nm
types? a. Paracrine

b. Autocrine
c. Neurohormonal
d. Hormonal
ANS: A nm
Paracrine signaling involves the release of local chemical mediators that are quickly taken
