ScienceAdaptionGCSEOCR Created by: AislingCreated on: 11-05-13 15:36 What is binocular vision? where eyes are at the front of the head, you can judge distance well 1 of 27 what is monocular vision? eyes at the side of the head, wide field of view. 2 of 27 How do prey stop from being caught? Living in groups. synchronous breeding (having young when predators aren't around e.g. summer). mimicry. 3 of 27 what are specialists? animals well adapted to live in ONLY specific habitats 4 of 27 what are generalists? can live in many different habitats. 5 of 27 what is the natural selection? survival of the fittest 6 of 27 what happened to peppered moths in polluted moths? there is more Black moths because they can camouflage 7 of 27 what is the difference between lamark and Darwins theroy? Dawins was about genetic inherication, Lamark is one animal changing in it's life time 8 of 27 why was Lamarks theory wrong? doesn't have genetic basis or evidence. 9 of 27 why is human population increasing? Exponential growth- birth rates exceeding death 10 of 27 What is a carbon footprint? the amount of greenhouse gas produced by a company or person in a certain time 11 of 27 What types of pollution is caused by humans? Household waste, sewage, Sulfur dioxide and Carbon dioxide from burning fossil fules 12 of 27 what are the causes and consequences of Ozone depletion? CFCs- holes in ozone- UV rays can get in- increased risk of skin cancer 13 of 27 what are the causes and consequences of acid rain? SULFUR DIOXIDE- dead trees, dead plants 14 of 27 what are the causes consequences of global warming? CARBON DIOXIDE- rise in sea levels 15 of 27 How can we tell if water is clean/ polluted? Mayfly lava- only lives in clean water. Water louse and Mussels can live in polluted water 16 of 27 What animal shows the air is clean? Lichen (grows on trees and rocks- never in citys) 17 of 27 what are direct methods of measuring pollution? oxygen probes, chemicals to indicate nitrate pollution. 18 of 27 Pros and Cons of measuring pollution with living and non-living methods? Using indicator organisms- cheaper, no equipment needed, monitors over a long period time. Equipment- more accurate at any specific time. 19 of 27 What are indicator Species? Organisms which live either in clean places or polluted areas. these can tell us how polluted the area is 20 of 27 Why do organisms become endangered? climate changes, habitat destruction, hunting, pollution, competition. 21 of 27 How can endangered species be conserved? captive breading programs, legal protection, protective habitats, education programs, creating artificial ecosystems. 22 of 27 Why create conservation programs? stops damage to food chains, protects our future food supply, in the future that animal may be used for medicines. 23 of 27 How can large numbers of species be at rick of extinction? if there is not genetic variation in the population 24 of 27 How are whales valuable? Food, oil, cosmetics. And tourism when alive 25 of 27 What is sustainable development? providing for the needs of today, and leaving enough for the future without harming the environment, e.g. replanting trees & and fishing quotas. 26 of 27 how do fish quatas protect fish? people are limited to the species, ammout and size of the fish they take 27 of 27
