Organisms that have lots of characteristics in common and can mate to produce fertile offspring. 1 of 36 What is competition? ‘Fighting’ with other organisms for resources. 2 of 36 What is migration? Moving to another area for part of the year. 3 of 36 What is prey? Animal that is eaten by another animal. 4 of 36 What is a predator? Animal that eats other animals. 5 of 36 What is adaptation? Characteristic that enables an organism to survive and be successful in its environment. 6 of 36 What is variation? Differences in characteristics. 7 of 36 What is continuous variation? Type of variation where a characteristic can take any value within a range. 8 of 36 What is discontinuous variation? Type of variation where a characteristic can only result in certain values. 9 of 36 What is interdependence? The way organisms depend on each other to survive, grow, and reproduce. 10 of 36 What do plants need to survive? Light and Minerals 11 of 36 What do animals need to survive? Food and Mates 12 of 36 What do both plants and animals need to survive? Space and Water 13 of 36 What are some Environmental variation examples? Pierced ears, scars and tattoos 14 of 36 what are some inherited variation examples? genetic diseases, blood group and eye colour 15 of 36 What can be both environmental and inherited variation examples? height, mass and intelligence 16 of 36 What apparatus can you use to find variation? Stop watch and tape measure 17 of 36 How do you find the time? distance divided by speed 18 of 36 how do you find the speed? distance divided by time 19 of 36 How do you find the distance? speed x time 20 of 36 What graph do you use to show results Histogram 21 of 36 What features does a histogram have? Histograms should have no space between the bars, the independent variable along the x axis and each bar should be represented by different variables. 22 of 36 What is endangered? species of plants and animals that have only a small population 23 of 36 What is a chromosome? long strand of DNA that contains many genes 24 of 36 What is a gene? section of DNA that holds the information to produce a characteristic 25 of 36 What is evolution? development of a species over time 26 of 36 What is DNA? chemical that contains all the information needed to make an organism 27 of 36 What is a nucleus? part of the cell where DNA is stored 28 of 36 What is a fossil? the remains of plants and animals that have now turned to stone 29 of 36 What is natural selection? the process by which organisms evolve 30 of 36 What is extinct? when no more individuals of a species are left anywhere in the world the species 31 of 36 What is a gene bank? a store of genetic samples from different species 32 of 36 How many chromosomes in a sperm cell? 23 33 of 36 How many chromosomes in a egg cell? 23 34 of 36 How many Chromosomes in a fertilised egg cell? 46 35 of 36 How many chromosomes in a normal body cell? 46 36 of 36
