Question

the unicorn is a legendary creature that has been described as resembling a horse, with a single spiraling horn in the center of its forehead. what role, if any, could the unicorn have in the science of biology?
a. the unicorn could be the subject of an investigation of horses.
b. the unicorn could be used to test new ideas about animal evolution.
c. the unicorn could provide data for the body structure of real animals.
d. the unicorn is not a real animal and, therefore, has no role in biological investigations.

evolutionary theory has become the central organizing principle of biological science. could this scientific theory ever become a scientific law?
a. yes, if scientists decide that enough evidence supports the theory.
b. yes, if the theory is shown to predict future events.
c. no, because a theory is a complex explanation that does not become a law.
d. no, because a theory can be proven correct while a law cannot be proven.

Explanation:

1. Unicorns are mythical and not real animals, so they cannot contribute to biological investigations which are based on real - world specimens.
2. A scientific theory is a well - substantiated explanation of some aspect of the natural world, while a scientific law is a statement that describes an observed phenomenon. Theories do not become laws as they serve different purposes in science.

Answer:

1. d. The unicorn is not a real animal and, therefore, has no role in biological investigations.
2. c. No, because a theory is a complex explanation that does not become a law.
