Question
K and R selected stratgeies are two types of evolutionary strategies which are used by two different type of species to survive in given environmental conditions.
Comparison of these two strategies :
| R - selected species | K-selected species |
| Produce many offspring | produce less offspring |
| Lifespan is short , usually small size organism | lifespan is long, usually large size organism |
| These species are weak competitors | These species are strong competitors |
| Tedencies for immigration and emigration is high | Tendicies for immigration and emigration is low |
| They could live in variable environment | They could only live in constant and predictable environmental conditions. |
| High mortality rates | Low mortality rates |
| Example include rabbits, bacteria, mice | Example include elephants, tortoises |

a) One problem that all respiring organisms share is the
need for biological structures that allow efficient uptake of
oxygen and removal of carbon dioxide. Two types of structures that
have evolved for carrying out gas exchange are gills and lungs. The

Chromosome translocations, generally, cause what types of cancers to develop? Provide two examples of chromosome translocations: one which causes elevated, deregulated levels of protein expression and one that leads to a change in protein structure. Explain each in detail. In your explanation include the names of the cancer types associated with each translocation.
