Review the discussion of evolution and the Investigating Life feature. Which of the following statements is/are most likely true? (Select all that apply.) Moths that could smell the nectar at the bottom of the orchid saw the need for a longer tongue, so they grew one that reached the nectar and passed on the longer tongue to their offspring. Moths that could smell the nectar at the bottom of the orchid mated with females that had longer tongues so that their offspring might have a chance to reach the nectar. At least one moth species has always been able to reach the nectar of the orchid. Moths with longer tongues are more likely to have access to the orchid nectar and are therefore more likely to survive to reproduction. Orchids with deeper nectaries are more likely to have moths rub against their pollen, and are therefore more likely to reproduce, than orchids with shallow nectaries.

This diagram illustrates a type of reproductive process in an organism. Parent Offspring A Based on this information, what conclusion about the offspring labeled "A" is supported? O It has acquired traits in response to its environment. O It has a lower mass of genetic material than offspring B. O It has the same genetic material as its parent. O It has half as much genetic material as its parent. INTL 01 https://student.masteryconnect.com/#
Give a Darwinian explanation of how cheetahs evolved to become faster. Your explanation is how natural selection works using Cheetahs as an example. Be sure to include andexplain the ideas of differential reproductive success and descent with modification. (You do not need to mention the formation of new species.)

Kettlewell's experiment is included in most biology texts as an example of evolution How do we know that the moths evolved?
Pedro believes that giraffes have long necks because they have stretched their 5) necks to try and reach food that is high in trees. Since the parent had stretched its neck, it passed the long neck on to its offspring. Ryan believes that giraffes have long necks because the ones with long necks were able to reach the food, and those with short necks could not and died. The long necked giraffes reproduced, and soon all of the giraffes had long necks. Which one of these arguments fits better with Darwin's theory of Natural Selection? Explain your reasoning.
Naturalists who have accepted evolutionary theory now propose that: all of the items listed extinction occurs when the food supply becomes nutritionally unbalanced O populations of plants and animals in nature most often consist of individuals that are clones of each other populations of a species that become isolated from others by adapting to different environmental niches quickly become extinct those individuals whose variation gives them an advantage in staying alive long enough to reproduce are more likely to pass their traits on to the next generation
Because many of the key mechanisms of evolution activate when sperm and egg combine, volutionary change happens faster for organisms with short life cycles (viruses, bacteria, fruit fly, yeast) compared to organisms with long life cycles (humans, elephants, tortoises). True False
In which of the following scenarios would evolution by natural selection take place? A banana tree branch is planted, producing a clone of the parent tree Microorganisms reproduce asexually, producing identical offspring Corn is genetically modified and cloned to make identical crops Penguins reproduce sexually, producing offspring that look different from one another
According to Darwin, which of the following would limit an individuals' reproductive success? Question 16 options: They display strong mate selection. They produce few and infrequent offspring. They are more likely to survive environmental changes than others in their species. They have many inheritable traits.
Evolution (Define) Compare and contrast the theories of evolution (Lamarck vs. Darwin) Evidences of evolution (explain and provide examples for all 6) Sexual vs. Asexual Reproduction (adv & disadv of both) Summary
Why is the following observation by Darwin important to the theory of evolution? "All species can produce more offspring than their environment can support, and many of these offspring fail to survive and reproduce" Organisms have evolved to produce as many offspring as possible Many organisms die for reasons having nothing to do with their evolutionary fitness Competition for resources creates the selection that drives evolution O Over time, organisms that have larger litters will be more evolutionarily successful
Which of the following are important ideas used by Darwin were based on views expressed by Lamarck? (Choose all that apply) Hint: review slide presentation which provides more detail than textbook O Changes that an organism acquires during its lifetime are passed to its offspring "acquired traits". D all species change through time Organisms change in response to their environment. New characteristics are passed from one generation to the next.
