Key point #1 Even the most desperate organisms share some features, suggesting that the single, nine random process generated diversity. True or False #1: biodiversity on earth will likely decrease in the near future. True! Fingerprints of human activity, spread of an invasive species, Rapid change and global climate, habitat destruction, Deforestation What are three Worlds Views? 1. Natural Evolution - Evolution by natural process 2. Theistic Evolution - Evolution guided by G...

base pair? correct answer: different nuclei types in DNA what is a gene? correct answer: What is the purpose of cell division? correct answer: Four events must occur for cell division: 1. Reproductive Signal -initiate cell division 2. Replication 3. Segregation 4. Cytokinesis Binary Fission correct answer: In prokaryotes, binary fission results 2 new cells.

In cats, white fur results from a gene that codes for tyrosinase, an enzyme that catalyzes the product'n of pigment. A mutat'n in this gene creates an allele coding for enzyme that cannot funct'n. Consequently, the cat fails to produce pigment and remains white. correct answer: False The F1 generat'n consisted of heterozygotes for the gene that codes for color. T/F correct answer: true None of the black cats in the F1 generat'n could have the mutant allele, b/c they lack white fur. ...
