Using binomial nomenclature, what would be the correct way of spelling the name of the grizzly bear?

Ursus Arctos
Ursus arctos
Ursus arctos
UrSuS aRcToS

Correct Answer

A. Ursus arctos

Explanation

In binomial nomenclature, the first name, representing the genus, is capitalized, while the second name, the species, is lowercase. Here, Ursus means bear in Latin, the genus the grizzly bear belongs to, and arctos means brown, as in brown bear.

A bat and a bee both have wings. What are these two structures?

Homologous structures
Derived character
Vestigial structures
Analogous structures

Correct Answer

A. Analogous structures

Explanation

Analogous structures are two structures that are very similar but have reached that point of similarity because of the environment, not inheritance. A bat and a bee are not even from the same phylum, yet they both have wings: this is not because their common ancestor had wings, rather because they each evolved to have wings because that characteristic made them more fit. A derived character is a trait that arose in the most recent common ancestor of a particular lineage and was passed along to its descendants. A vestigial structure is a structure which, although has no use to the organism today, still exists because it didn't harm that organism, such as the hipbone of a dolphin (who evolved from land walkers, whose hipbones were legs), or our appendix.

What type of evidence about an organism is best for a discerning evolutionary relationships?

External physical characteristics, such as skin color, face shape, and hair.
Internal body structure, especially bone structure and organs
Location on earth
DNA

Correct Answer

A. DNA

Explanation

Since DNA is the basic genetic information for every living being, it tells us most about our true nature and relationship with other beings.

Domain, kingdom, genus, order, class, family, phylum, species
Domain, kingdom, phylum, class, order, family, genus, species
Domain, kingdom, phylum, class, family, order, genus, species

Correct Answer

A. Domain, kingdom, phylum, class, order, family, genus, species

The taxonomic system is rigid and will always remain the same

True
False

Correct Answer

A. False

Explanation

Scientists are constantly learning new things about organisms: as they do, the taxonomic classification shifts around and changes. Although obviously animals evolved a certain specific way, our understanding of it is incomplete, and therefore our taxonomic system changes all the time. Example: 30 years ago, there were only 3 kingdoms: Plants, Animals, and Squiggly Things. Today there are five (or six).

What criteria do taxonomists use in categorizing organisms?

Reproductive Behavior
Geographic Location
Biochemistry
Size
Intelligence
Anatomical Structure
Behavior
Motivation
DNA
Embryological Development

Correct Answer(s)

A. Reproductive Behavior
A. Biochemistry
A. Anatomical Structure
A. Behavior
A. DNA
A. Embryological Development

Explanation

Taxonomists use several criteria to categorize organisms. Reproductive behavior is one such criterion, as it helps determine the similarities and differences in how organisms reproduce. Biochemistry is another important factor, as it involves studying the chemical composition and processes within organisms. Anatomical structure is also crucial, as it involves comparing the physical characteristics and body structures of different organisms. Behavior is considered as it helps identify patterns and traits in how organisms act. DNA is used for genetic comparisons, while embryological development helps understand the developmental stages of organisms. These criteria collectively provide taxonomists with a comprehensive understanding of the relationships and classifications of organisms.

What phylum to hydra and jellyfish belong to?

Cnidaria (Coelenterata)
Annelida (Segmented Worms)
Arthropods
Chordata

Correct Answer

A. Cnidaria (Coelenterata)

Explanation

Cnidaria (Coelenterata) are aquatic, soft-bodied, carnivorous animals who have stinging tentacles and are highly symmetrical. They have no internal circulation system and diffusion happens through their body cells.
