Figure 1.7 Taxonomic classification of five species that are related at different levels.
Each species has been assigned to ever more inclusive groups, or taxa: in this case, from genus to domain.

Figure It Out: Which of the plants shown here are in the same order?
Taxonomy involves the identification of different organisms, classification of the identified organisms into categories, and naming them. The organisms are classified into different groups along with other similar organisms. Eight different taxonomic categories are there, namely domain, kingdom, phylum, class, order, family, genus, and species.
Explanation of Solution
An order is a taxonomic rank that is used for classifying organisms. Order is more specific when compared to class, a taxonomic rank above the order. The plants given in the figure are wild carrot, marijuana, prickly rose, apple, and dog rose. Among the given flowers, marijuana, apple, dog rose, and prickly rose belongs to the same order Rosales.

- PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen. How would increased estrogen affect the river otter population?

Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.arrow_forwardOther than oil and alcohol, are there other liquids you could compare to water (that are liquid at room temperature)?

You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different. (Editor’s note: Providing this information in your discussion will help readers to consider the significance of the research).arrow_forward
