Question 1 1) What is the correct order from highest level to... lowest level of taxonomic hierarchy? Question options: Order, family, genus, species Genus, species, order, family Species, genus, family, order Family, order, genus, species Hide Feedback Great. Question 2 2) Which is a single cell that lacks membrane bound organelles? Question options: Eukaryote Prokaryote Ribosomes Nucleolus Hide Feedback Great. Question 3 3) Which type of science seeks to use science to solver real-world problems? Question options: natural basic empirical applied Hide Feedback Great. Question 4 What process do scientists use as a way to perform research with defined steps that include experiments and careful observation? Question options: The scientific method A clean lab bench A journal article The right hypothesis Hide Feedback Great job. Question 5 What is the main reason offspring will belong to the same species as the parents? Question options: They share the same habitat. They share the same genes. They share the same food. They share the same environment. Hide Feedback Great. Question 6 Which type of science seeks to expand knowledge regardless of the short-term application of that knowledge? Question options: natural empirical applied basic Hide Feedback Great. Question 7 Which statement would be a hypothesis using the scientific method? Question options: Why isn't my grass growing? If my sprinklers are not working, then my flowers will also die. My grass is not growing. There must be something wrong with my sprinkler. I turn on my sprinklers. Hide Feedback Remember, the hypothesis works to answer your question, and a prediction is based on the hypothesis, so they may sound similar. Review the scientific process in Chapter 1. Question 8 What is the term for an organisms' ability to maintain constant internal conditions even when environmental conditions change? Question options: Equality Equilibrium Homeostasis Centered Hide Feedback Great. Question 9 What is an example of a response to stimuli in a living organism? Question options: A bear hibernating in the winter A bacteria taking up nutrients from the soil A plant bending towards the sun A fungi crawling away from a person Hide Feedback Great. Question 10 What is microevolution? Question options: due to detrimental effects on fitness. the field of study which examine allele frequencies. the change in allele frequency in a population. the change that gives rise to new species. Hide Feedback Great job. Question 11 Which of the following is accurate about mutation? Question options: Mutation is the ultimate source of novel variation. Mutation causes gene flow between populations. Mutation alone is a strong mechanism of evolution. Mutation results from bottleneck events. Hide Feedback Although there are many processes that can change allele frequencies in a population, only mutation can result in new variation. Read more in Chapter 11. Question 12 How did Darwin define evolution? Question options: adaptation to climate descent with modification change in allele frequency over time inheritance of acquired characteristics Hide Feedback Great job. Question 13 A classic scientific study showed that crayfish on one side of the isthmus of Panama were more closely related to other species on the other side of the isthmus than to each other. The most likely explanation for this result is: Question options: dispersal mutation gene flow vicariance Hide Feedback The most likely explanation is that a several separation crayfish species were separated by the formation of the isthmus and the then separated populations diverged. Read more in Chapter 11. Question 14 A population of pocket mice has two coat colors: black and brown. There are more black mice on lava rocks where there are hawk predators. This is an example of: Question options: Genetic drift Natural selection Macroevolution Mutation Hide Feedback Great job. Question 15 What is an example of gene flow? Question options: Purple alleles are introduced into population by migration. In a population flowers that carry purple alleles are pollinated more often. Purple alleles result in allopatric speciation. A new purple allele arises in the population by mutation. Hide Feedback Great job. Question 16 What does the famous quote from Theodosius Dobzhansky "Nothing makes sense in biology except in the light of evolution"? Question options: This quote means that since every species eventually goes extinct we must try to understand biology before this happens. This quote means that many questions about evolution are still being answered so we should seek to understand those first. This quote means that all other questions in biology are tied together by the diversification over time from a common ancestor. This quote means that the thermodynamic principles that govern light are important to how organisms have diversified over time. Hide Feedback Great job. Question 17 What is a vestigial structure? Question options: A physical characteristic that does not have a function but does have a function in ancestral species. An analogous characteristic that is similar between unrelated species. A trait that results from a particular type of mutation during development. An anatomical trait that changes during development from small to large. Hide Feedback Great job. Question 18 What is one of the three principles that results in natural selection? Question options: Characteristics are inherited from parent to offspring. Individuals in a population have the same ability to survive and reproduce. Inheritance of acquired characteristics creates a strong evolutionary force. Resources are unlimited and arise from the endless supply of energy from the sun. Hide Feedback Great job. Question 19 Malaria acts as a natural selective agent so that people with what disorder have a survival advantage? Question options: Thalassemia Hemophilia Cystic Fibrosis Fragile X Syndrom [Show More]
