Step by step
Solved in 2 steps
- Biodiversity is described as: The seasonal and daily changes in an environment The range of different species in an environment The influence of physical factors on an environment The way species differ from one anotherthe greenhouse effect is a increase in air temperature caused by gases trapping --- radiation natural, short-wave ultraviolet natural, long-wave infrared human-cause, long-wave infrared human-caused, short-wave ultravioletGive me an example of a sudden change and a gradual change can causes extinction to population of organisms.
- What happens to a species that is pushed outside its fundamental niche? It evolves and adapts It experiences rapid population growth It goes extinct It speciates into a new speciesUnit #5: Ecology and Evolution World’s average ecological footprint = 2.84 gha/person (world total: 20.1 billion gha used/year) World’s biocapacity = 1.73 gha/person (12.2 billion in total) What does this mean? Under what circumstances might investigators choose to do one type of analysis versus the other (mtDNA vs. Y chromosome DNA)?What is meant by interaction that happen among species is diffuse
- The Colorado potato beetle has a history of pesticide resistance. The graph shows the number of chemical insecticides used in agriculture that the Colorado beetle population has become resistant to from 1950 to 2010. It took longer for the population of potato beetle to develop a resistance to some insecticides. However, by 1990, the Colorado potato beetle population had developed a resistance to 35 different kinds of insecticides, and farmers ran out of insecticides they could use to control the beetle population. A new type of insecticide was introduced in 1995. 60 40 30 20 10 1960 1970 1980 1990 2000 Year of Report Which of the following best describes what happened from 1965 to 1975 and again from 1995 to 2000 to the insecticide resistance of the beetle population? The Colorado beetle gene pool for insecticide resistance was identical and the insecticide had no effect on the beetle population, which is why it continued to increase. The introduced insecticides were effective for a…Which of the following is a symbiotic relationship?

- Due to its ability to camouflage itself from predators, the White Peppered Moth of England was once much more abundant than the Black Peppered Moth. As the Industrial Revolution hit, factories began to release black soot which coated everything, including tree bark. Because the moths’ habitat was now darker, the white moth became much more susceptible to predators. At the same time, the Black Peppered Moth was now more protected and began to increase in number.This story is an example of A. natural selection. B. extinction. C. endangered species. D. mutation.Read this quote from Charles Darwin (from Origin of Species). What is he describing? "Thus, I can understand how a flower and a bee might slowly become, either simultaneously or one after the other, modified and adapted to each other in the most perfect manner, by the continued preservation of all the individuals which presented slight deviations of structure mutually favorable to one another." An interaction network. A predator/prey cycle. O Coevolution. An obligate mutualism.Which of the following is not a mutualistic relationship? a shark using an aquatic cleaning station a helminth feeding from its host a bumblebee collecting pollen from a flower bacteria living in the gut of humans
