Why is a species with small population more likely than one with a large population to undergo an extinction? * a. Because small population are exposed to greater environmental changes b. Because genetic diversity is likely to be lower in a small population c. Because the mutation rate is too low d. Because they take too long to produce an offspring.

Modern taxonomic treatments rely heavily on phylogenetic data to classify organisms. In the past, taxonomists often used a morphological species concept, in which species were defined based on similarities in growth form. Give an example of how a morphological species concept would group a set of protists differently from how a phylogenetic species concept would.
Some non-plant organisms like the protist that spreads malaria contain a non-photosynthetic chloroplast called an apicoplast. Crazy! What best explains how protists have evolved apicoplasts? Select one: a. phosphorylation acts as a molecule switch b. the central dogma of biology C. the endosymbiotic theory O d. sympatric speciation O e. chemiosmosis e Dec 8 at 5pm Jump to... → Next page
In this data table comparing DNA sequences among various protists, why do some cells have a dash rather than a value? A. Those cells would compare one species to itself. B. Those cells would duplicate comparisons shown elsewhere in the matrix. C. Those comparisons were not made by the researchers.
Why is the classification of protists based on DNA sequences considered useful? a. Because only protists have DNA b. Because genetic sequences have confirmed the traditional categories of protists c. Because DNA reveals evolutionary relationships, even among organisms that look different d. All of the above are correct.
A group of environmentalists is studying the effects of recent commercial zoning to wildlife acreage on the biodiversity of a rural county. The group noted a steady decline in the population of animals, while bacteria and other protists remained constant. Which statement best discusses the reasons for the steady decline of animals as opposed to the protists? A. Bacterial growth is usually not affected by environmental changes because of asexual reproduction. B. The animals could not adapt to the new environment. C. Bacteria lived in areas that were not affected by the zoning D. The animals became susceptible to human and environmental harm.
Give three examples of protists for which the classifications haverecently changed. In each case, what was the justification for the oldcategory, and what is the justification for the change?
Which pair of species would be the most similar? a. Both are in the same kingdom but different phyla b. Both are in the same phylum but different classes O c. Both are in the same class but different orders d. Both are in the same order but in different genus O e. Both are in the same Domain but different Kingdom
