|
5 main groups to classify Vertebrates |
(Vertebrates have a backbones) ▪Reproduction - viviparpus, young developed in body of parent. Others are oviparous meaning hatched in egg. ▪Thermoregulation - control own body temperature, homeotherm. Others body temperature varies I'm accordance with to environment like, poikilotherm. ▪Fertilisation - internal or external. ▪Oxygen absorption - use gill or lungs (young amphibians have gills, adult amphibians use lungs, frogs) |
|
|
Species |
A group of organisms that can breed with eachother to produce fertile offspring. |
|
|
Hybrids |
When species interbreed (breed with other species) to produce sterile offspring (cannot produce offspring) |
|
|
Why are binomial names useful? |
▪Other people know what species you mean. ▪You can see from the genus which species are closely related ▪Helps identify which environments contain fewest species (low biodiversity) that are the most at risk of extinction. |
|
|
Types of variation |
▪Discontinuous variation - characteristics controlled by genes (genetic variation) hence blood group or gender ▪Continuous variation - characteristics varies gradually and Continuously between extremes hence height or weight. ▪Normal distribution graph - bell shape that most common variation lies between 2 extremes. |
