Adaptation is an important component for species survival. Genes get selected for based on pressures. It is now
known that several species (bacteria, plants, and animals) adaptions potentially reflect a response to human
actions. Which of the following represent examples of how species are adapting to human behaviors? Choose all
that apply.
O Dandelions getting longer in areas that are constantly mowed
O Bacteria exhibiting antibiotic resistance
O The peppered moth expressing dark coloration genes during the industrial revolution
O Cholera bacteria becoming more mild when water sources are cleaner
r-selected species display all of the following traits, except:
A) Population size is density dependent
B They have large numbers of offspring
Most offspring are short-lived
D) There is little parental care
What are some potential solutions to decrease the threat/endangerment of sea turtles? What can humans do? What are some solutions that scientist or convervationist tried to do to help sea turtles? What is one hypothesis on further environmental, ecological, biodiversity or other biological problems that this solution might intentionally or unintentionally create?

Provide at least 3 reasons in favor of this and 3 against the reintroduction of native species.arrow_forwardWhich of the following is not part of how we define a species? a. Its individuals appear different from other species. b. It is reproductively isolated from other species. c. Its populations can interbreed. d. Fertile offspring are produced.arrow_forward
- Why are nonnative species often considered a disturbance in an ecosystem? They increase mutations. They compete for resources. They have special growth needs. They cause increased biodiversity.arrow_forwardExplain at least one (1) adaption that our species may develop to continue surviving on eartharrow_forwardA A Ao Question 45 The atmosphere is an important source of both carbon and oxygen in aquatic systems.

- All of the following are true of primate dispersal, EXCEPT: It helps prevent inbreeding Most transfers of males occur during the breeding season the philopatric sex is the one that disperses Joining a new group can be difficult and have high costs to the new individualarrow_forward2) In a particular island, the environment is semi-arid. There is a lizard population with a lot of variation for color. Normally, the light sandy color and golden colored lizard flourished because they escaped predation, while others were barely surviving. However, in recent years, a lot of rain has brought about a lot of vegetation. Which variation of lizard will now flourish in the area? * A) white B) Brown C) Green D) Redarrow_forwardYou are comparing species diversity between four different habitats: which of the following habitats is the most diverse? Habitat A has 15 species total, with approximately equal representation across all species Habitat B has 15 species total, and is dominated by two of its fifteen species Habitat C has 3 species total, with approximately equal representation across all species Habitat D has 3 species total, and is dominated by one of its three species Habitats A and B are equally diversearrow_forward
- Threats to Biodiversity Match each description to the type of threat it presents to biodiversity. NOTE: If you want to change your selection, you'll need to delete the one you already chose. After you delete it, the list of choices will pop back up and you can make a different choice Burning fossil fuels and cutting down forests habitat loss Replacing grassland with neighborhoods climate change Accidentally or purposefully moving an organism from one place to exotic species another overharvesting Many people fishing for the same speciesarrow_forwardThere are six species of animals in an area at the end of Thunder Bay. The area is wooded land covering rolling hills with two small rivers. Most of the area is surrounded by farm land where people have sheep and cows. There are three roads in the area, one of which leads to an expanding subdivision. a) Chose the species you believe to be most likely to become endangered and the species you believe to be least likely to become endangered. Compare and contrast these two species to explain your decision b) Which two species do you think would be most likely to exhibit a competitive relationship? c) Explain two density-dependent factors that may affect population P in this area d) Explain two density-independent factors that may affect population P in this areaarrow_forward. As coral reef communities continue to experience ocean acidification and bleaching, a population of gobbie fish and their allelic variability has rapidly decreased, this is an example of a) founder effect b) mutation c) natural selection d) gene flow e) bottleneck effectarrow_forward
