Chapter 26: Animal Systems II Review

Front

What are the diploid (2N) stages of the Aurelia life cycle?

Back

The diploid stages include the Female medusa, Male medusa, Young medusas, Swimming larva, and stages 3 and 4.

Front

What is the advantage of alternating between asexual and sexual reproduction in Aurelia?

Back

It increases genetic diversity and allows rapid population growth.

Front

What is the role of interneurons in a neural circuit?

Back

Interneurons allow for the processing of sensory information, enabling more complex responses to stimuli.

Front

How can you accurately model the exoskeleton of a grasshopper?

Back

By covering the foam organs with a thin but tough outer coating.

Front

What happens to the muscles crossing the shoulder joint when lifting the arm?

Back

Some muscles contract while others relax.

Front

Define diploid (2N).

Back

A diploid cell has two complete sets of chromosomes, one from each parent.

Front

What is a medusa in the context of Aurelia?

Back

A medusa is the adult, free-swimming stage of the Aurelia life cycle.

Front

Explain the concept of asexual reproduction.

Back

Asexual reproduction is a mode of reproduction where offspring are produced from a single parent without the involvement of gametes.

Front

What is the significance of genetic diversity in populations?

Back

Genetic diversity increases a population's ability to adapt to changing environments and resist diseases.

Front

What is the function of sensory neurons?

Back

Sensory neurons transmit sensory information from receptors to the central nervous system.
