B. use an amoeboid type of movement. C. classification system is trying to reflect phylogenetic relationships. D. appear to be more closely related to unicellular eukaryotes.arrow_forwardSome non-plant organisms like the protist that spreads malaria contain a non-photosynthetic chloroplast called an apicoplast.

- You have discovered a photosynthetic protist that lives in fairly deep water (for example, 250 m deep). To which of the following groups should this organism be classified? A. diatoms B. green algae C. red algae D. cercozoanarrow_forwardWhich of the following taxon contains the other? a. Species b. Class c. Order d. Genusarrow_forwardWhy is the classification of protists based on DNA sequences useful? * a. Because only protists have DNA b. Because it has confirmed the traditional categories for protists c. Because it has revealed evolutionary relationships, even among organisms that look diffferent d. All of the above are correct This is a required question (2) 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.

The group includes the most recent common ancestor and all the descendants D. They share several morphological similarities with land plantsarrow_forwardModern 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.
