Answers 2024

how many species live in planet Earth? - Correct Answer-unknown-roughly 3 to 5 million why is life so incredibly diverse, yet so strangely similar? - Correct Answer-organisms can contain similar features. planes have wings, birds have wings-this feature is useful for different things (different for penguins, pelicans, bats, eagles) true or false: biodiversity on earth will likely decrease in the near future? - Correct Answer- true or false: scientists believe in evolution even though they currently lack evidence for the theory - Correct Answer-false true or false: opposition to irrational numbers was based on evidence that such numbers cannot exist - Correct Answer-false true or false: opposition to irrational numbers stemmed from a worldview involving naturalistic evolution - Correct Answer-false true or false: the belief that irrational numbers cannot exist reflects religion more than science - Correct Answer-true true or false: modern mathematicians accept irrational numbers because such numbers provide more accurate solutions to problems than whole numbers do - Correct Answer- true the scientific method relies on.... - Correct Answer-models, observations, and experiments a model is a formal description of a scientific hypothesis. which provides the most precise description of a hypothesis? - Correct Answer- true or false: an experiment enables one to demonstrate that a correlation between two variables results from cause and effect - Correct Answer-true a well designed experiment... - Correct Answer-controls for environmental and genetic factors, involves replications of experimental subjects, and randomizes experimental subject among treatments true or false: unlike Wallace, Darwin did not believe that natural selection required variation among individuals - Correct Answer-false

true or false: Wallace used induction to develop a model of evolution by natural selection - Correct Answer-true unlike Wallace, Darwin's conceived his theory of evolution without observing species living on islands - Correct Answer-false true or false: both Darwin and Wallace must have assumed that differences among individuals were passed onto their offspring - Correct Answer-true true or false: similar to Wallace, Darwin conceived a theory of evolution by natural selection while voyaging around the world - Correct Answer-false true or false: both Wallace and Darwin adopted a worldview described as either naturalistic evolution or theistic evolutions - Correct Answer-true true or false: a probability of 0.98 means that an event occurs rarely - Correct Answer- false true or false: when a parent is heterozygous, the probability of passing the dominant allele to its offspring is 25% - Correct Answer-false true or false: when both parents are heterozygous (Aa), the probability of an offspring being homozygous recessive (aa) equals 0.25 - Correct Answer-true true or false: a punnett square enables one to determine the frequency of observed genotypes without using a mathematical formula to calculate the joint probability - Correct Answer-true true or false: when both parents are heterozygous (Aa) equals 0.75 - Correct Answer- false when one copy of an allele determines the phenotype of an individual - Correct Answer- dominant when two copies of an allele are needed to express a certain phenotype - Correct Answer-recessive when an individual carries two different alleles for a gene - Correct Answer- heterozygous when an individual carries two identical alleles for a gene - Correct Answer-homozygous when two chromosomes contain the same genes - Correct Answer-homologous when the variation in a phenotype depends on genes - Correct Answer-heritable

when a cell contains two copies of each chromosome - Correct Answer-diploid when a cell contains one copy of each chromosome - Correct Answer-haploid a characteristic of an organism that varies genetically - Correct Answer-trait a description of an organism's appearance or behavior - Correct Answer-phenotype an error in the sequence of nucleotides when copying DNA - Correct Answer-mutation a form of a gene that affects the way an organism looks or behaves - Correct Answer- allele the set of alleles that determine how an organism looks or behaves - Correct Answer- genotype a place on a chromosome where a certain gene occurs - Correct Answer-locus a linear sequence of DNA that codes for a certain protein - Correct Answer-gene a process in which a diploid cell produces four haploid cells - Correct Answer-meiosis a process in which a diploid cell produces two diploid cells - Correct Answer-mitosis a highly condensed molecule of DNA that codes for many proteins - Correct Answer- chromosome a hapliod cell that develops into a sperm or an egg - Correct Answer-gamete the diploid cell that results from fertilization between sperm and egg - Correct Answer- zygote when a cell prepares to divide, it must copy its DNA such that each daughter cells ends up with all of the necessary genetic material - Correct Answer-DNA replication thought there was an inheritance of acquired traits-like giraffes and their long necks - Correct Answer-Ideas of Lamarck evolution by natural process - Correct Answer-natural evolution evolution guided by god - Correct Answer-theistic evolution species created by God - Correct Answer-creation

the ability of a microorganism to withstand the effects of an antibiotic-evolves naturally via natural selection through random mutation - Correct Answer-antibiotic resistance estimates the degree of variation in a phenotypic trait in a population that is due to genetic variation between individuals in that population - Correct Answer-heritability
