Evolution is a scientific law, theory, and fact. True False QUESTION 24 What are some conclusions we can make? Select all that apply. Evolution... causes good traits to appear in populations results in changes in individuals is affected by random and non-random factors Which is the best definition of natural selection? survival of the fittest (don't pick this one!) individuals becoming better adapted to nature survival and reproduction of those who have adaptations the change of the genes of a popuation over generations QUESTION 6 Genetic drift is the change in the genetic make-up of a population due to random chance. In each generation, some individuals may, just by chance, survive and reproduce more than others. Which one or more of the following is an example(s) of genetic drift? Select all that apply. American bison were once very prevalent in North America but were hunted close to extinction in the late 1800s. The populations are recovering, but a lot of genetic variation was lost. A single bacterium has a mutation which makes it resistant to an antibiotic. It shares this whe with neighboring bacteria, and soon the population grows uncontrolled. A farmer grows tomatoes and sells them at a local farmers market. A population of rabbits have brown fur and white fur with brown fur being the dominant allele. Neither allele increases survival or reproduction. But over several generations the offspring are all brown. Adaptations...(select all that apply) change when an organism needs a new characteristic to survive can be modified in a new environment are traits determined by genes are bencial traits in that environment QUESTION 3 Individuals in a population are not identical \( \checkmark \) and the source of new allele combinations are \( \checkmark \), which is also known as migration. QUESTION 2 Which one or more of the following is an example(s) of biological evolution? Select all that apply. A spider carries a mutation that codes for a protein that breaks down bug spray, essentially making the spider immune. wildfire takes out a large porportion of the forest, which happened to include wiping out most of the vines which had narrow leaves. A population of red and white flowers starts approximately equally distributed in color. A swarm of pests can easily see and eat the red flowers, leaving primarily the white flowers alone. In the next generation there are approxiamtely the same number of flowers, but more of them are white. First, let's look at an overview of evolution Put these phrases in the correct order to create the definition of biological evolution \( -\vee \) of a population \( -\sim \) over time \( -\sim \) the change \( -\sim \) of the genetic makeup Identify three food chains in the food web above. Each food chain should start with a producer and end with a decomposer. Fill in the organisms' names below. Think back to the Explore activity What could you have added to the cup to help the earthworm survive? Explain.
