____________ are mutated genes that cause cancers: - Proto-oncogenes ________________ are proteins produced by the immune system - antibodies 75% of increase in CO2 is due to: - Fossil fuels A benign tumor - A non spreading tumor (harmless) but can later become malignant A bundle of axons is called: - nerves A naturalized alien species is: - an alien species that has established itself and becomes a selfperpetuating population become widely dispersed and incorporated into native ecosystem A reason that adaptive radiation has occurred so often is Hawaii is: - Large range of environmental diversity temperature soil moisture eg rainfall vegetation led to great diversity A second exposure to a foreign invader will produce a more _________ response. - faster larger response A species that is likely to become endangered in the future is called ________. - threatenedAfter Europeans made their discovery of Hawaii, they would cause as mush damage to the Hawaiian biota in 200 years as the Hawaiian had in ________ centuries - 20 BRCA 1 &2 are: - Breast Cancer Suspecptibility genes/mutated copies of genes Can surgery cure cancer that has metastasized? - No, cancer cells are no longer localized in one spot Conservation biology is considered a synthetic field because : - A mixture of applied and theoretical fields. Efforts to save the Hawaiian biota includes: - Control of alien species: fencing, biological contro, weeding, herbicide, hunting habitat =restoration Genes that are mutated in cancer cells often control: - Regulating the cell cycle Global warming and ozone depletion are related problems because: - Chlrofluorocarbons (CFCS) that cause ozone depletion are greenhouse gases that also cause global warming Goats caused more damage to plants in the mountainsides of Hawaii than cattle because: - They were able to eat plants on the mountains that the other cattle couldn't eat Hormones are: - Chemical messengers produce in one part of the body with action in another Major roles; control development regulate physiology Found in plants and animals Causes stimulation/inhibition -types proteins and amino acid likesteroids phospholipids How are marine invasive species dispersed throughout the world? - Global movement of organisms through vehicles that travel around the world by ocean How do bacteria arise? - Overuse of antibiotics antibiotics kill majority of bacteria, but a few immune to the antibiotics survive surviving bacteria with immunity to reproduce and displace bacteria susceptible to antibiotics Humans are responsible for the loss of native habitats in species and extinction by: - agriculture cattle grazing feral animals pigs goats sheep deer urbanization in 1994, all the CEOs of all the big tobacco industry, stood up, under oath and told congress that nicotine ____________ - wasn't addictive In nearly the greatest mass extinction in modern time, nearly_________ percent of all native Hawaiian birds have disappeared forever - 70 In the BD disease of amphibians what does the phrase "canary in a cool mine" mean? - BD=Batrachochytrium dendrobatidis Canary in a cool mine=a warning to humans It was previously not possible to drill for oil in the Russian arctic, but now it is possible. Why? - They lied IUCN stands for : - International Union for the Conservation NatureListing species as endangered based upon ________. - the best scientific data available and not economics Most cancers involve ________ gene mutations - minimum 6-9 acquired Naomi Oreskes read 928 papers on science articles having to do with climate change, and determined that ___________ % of scientist concluded that climate change was occurring while ________ % disagreed. - 100%, 0% Native species that are only found in Hawaii are_________, while those found elsewhere are _____________. - Endemic, indigenous natural killer cells are specialized white blood cells that: - Do not attack invading cells attack abnormals cells i.e. virus infected cells, cancerous cells and cells without proper recognition sites
