Step by step
Solved in 3 steps
- two species of bateria, A and B, live in the gut of fruit flies. Bacteria species A benefits by receiving food from the fly and aids the fly by helping its digestion. Bacteria species B benefits by receiving food from the fly and harms the fly by attacking cells in the lining of the gut. Which of the following statements characterizes these relationships? a. Species A is a symbiont and mutualist, while species B is not a symbiont and is a parasite. b. both species are both symbionts and parasites c. species A is a symbiont and species B is a parasite d. both species are symbionts. species A is a mutualist and species B is a parasiteWhat is Allopatric speciation? A) When a population is separated from the main group by a barrier and becomes a new species B) When a population mutates into a new species C) When a population develops into a new species without any physical barriers to isolate themWhen the isthmus of Panama (land bridge that connects north and south America) arose about 3 million years ago, it caused species of fish to diverge into sister species located in either the caribean or pacific ocean. Why did they form separate species? A) Because this is an example of sympatric speciation B) Because the tides are different on each side of the land bridge C) Because different predators in each ocean caused the populations to diverge D) Because the populations were reproductively isolated
- What is Sympatric speciation? A) When a population is separated from the main group by a barrier and becomes a new species B) When a population mutates into a new species C) When a population develops into a new species without any physical barriers to isolate themIdentify each of the following groups of species as a monophyletic group (clade), a paraphyletic group, or a polyphyletic group. a) Brown bear, Polar bear, D, G b) Sun bear, Sloth bear, Spectacled bear c) Sun bear, Asian black bear, American black bear, E, FFor the metapopulation of Daphnia in Scandinavian freshwater pools, which situation would be most likely to result in maintenance of the metapopulation, rather than its extinction? A) Immigrants increase the genetic diversity of pools, slightly increasing r. B) Years of drought decrease the average size of all pools. C) Small pools “wink off” and are not repopulated by dispersal from larger pools. D) The pools are mostly small, and there is no dispersal among them. E) Dispersal among pools is infrequent, and many pools reach zero density.
- Identify a species that your group thinks is ok to drive to extinction and justify the reasons for this decision. Can you anticipate any consequences of losing this species from the Earth?Please explain why you decided to pick an answer choice. Explain your reasoning/rational/logic for choosing the answer choice. Question: Which of the following hypothetical islands would likely have the greatest species richness? Group of answer choices A) Not enough information given B) a large island far from the mainland C) a large island near to the mainlandWhat is the relationship between the concept of reproductive and geographical isolation and the concept of species? Illustrate and give concrete examples.
- Clade A began diversifying 20 million years ago. There are 33 living species in Clade A and 6 species have gone extinct. Clade B began diversifying 10 million years ago. It has 14 living species and 5 species in Clade B have gone extinct. CALCULATE SPECIATION, EXTINCTION AND NET DIVERSIFICATION RATE (to the nearest 2 decimal places) TO DETERMINE WHETHER NET DIVERSIFICATION DIFFERS BETWEEN THE TWO CLADES. Clade B has higher net diversification because despite having a higher extinction rate, it also has a higher speciation rate compared with Clade A. Clade A has higher net diversification because despite having a lower speciation rate, it also has a lower extinction rate compared with Clade B. Clade A has higher net diversification because it has both a higher speciation rate and a lower extinction rate than Clade B. Clades A and B have the same net diversification; Clade A has a higher speciation rate, but Clade B has a lower extinction rate. Clades A and B have the same net…Is the species a generalist or a specialist and how does this niche impact the species of the wild. The giant panda, native to China, and the raccoon, native to North America, share a common ancestor. However, their current status in the wild is anything but common.What is Speciation? A) Movement of a population from one area to another B) Becoming part of an adopted species C) Creation of a new species
