how many species live in planet Earth? - ANSWER-unknown-roughly 3 to 5 million why is life so incredibly diverse, yet so strangely similar? - 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? - ANSWER- true or false: scientists believe in evolution even though they currently lack eviden...

BIO 121 Exam 3 Questions And Answers Whole-gene The molecular level describes genetic variation as nucleotide variability. Although populations do vary in their characteristics, it is at the gene level that genetic variation can be quantified. Although species do vary in their characteristics, it is at the gene level that genetic variation can be quantified. Individuals may vary in a population, but it is at the gene level that genetic variation can be quantified. - ANS At wha...

Adaptive Radiation - An evolutionary pattern in which many species evolve from a single ancestral species Allele - An alternative form of a gene. Allele Frequency - Number of times that an allele occurs in a gene pool in comparison to the total number of alleles allopatric speciation - The formation of new species in populations that are geographically isolated from one another. allopolyploidy - a species with multiple sets of chromosomes derived from different species Alpha (origination...

convergent evolution - unrelated or distantly related organisms evolve similar body forms, coloration, organs, and adaptations natural selection - the process whereby organisms better adapted to their environment tend to survive and produce more offspring (acts on individuals but populations evolve) Judeo- Christian perspective - The Creator: God made everything Linnaeus - Binomial nomenclature and nested classification system Cuvier - fossils in strata- catastrophism Hutton and Lyell - g...

Humans produce sweat as a cooling mechanism to maintain a stable internal temperature. Which of the following best explains how the properties of water contribute to this physiological process? - ANSWER The high heat of vaporization of water allows the body to remove excess heat through a phase change of water from liquid to gas A student placed a semipermeable membrane inside a U-shaped channel with two chambers, as shown. The membrane permits the movement of water but not salt. The...
