Biological Evolution Unit Test (Connexus) Solved 100% Correct!!

Which competition is direct and interspecific? - a hyena and cheetah fighting over a carcass Suppose the mosquito population in an area increases. Which organism may also experience a population increase? - bats A mutation is any - change in the DNA sequence. Why is genetic variation among individuals beneficial? - Some individuals will have inherited traits that give them a competitive advantage that make them more likely to survive and reproduce. Cactus finches have long, pointed beaks. Say the only source of food for Cactus finches is cactus flowers. If a plant disease killed a large portion of the cacti on the Galapagos islands, how would the population of Cactus finches change? - The population of Cactus finches would decrease because there would be more competition for food. What is the term used to describe having a trait that can be passed on to subsequent generations that increases the organism's ability to survive in its environment and reproduce? - adaptation Rabbits can exhibit a number of colors in their coats: black, white, tan, brown, red, and grey. A disease randomly kills off most of the population and leaves only black and grey rabbits. Future generations are only black or grey. What is the term used to describe this phenomenon? - genetic drift How are genetic modification and artificial selection similar? - Both result from human influences. The "great dying," which saw 96% of all species extinct, was partially caused by - bacteria producing large amounts of toxic methane. Which situation is an example of altruistic behavior? - A child shares an apple.If an organism is well adapted to its environment and a rapid major change occurs to the environment, what is most likely going to happen to the organism? - The organism will not be able to adapt, and the species will go extinct
