The more destructive earthquakes typically have magnitudes between about 5.5 and 8.9; the scale is logarithmic and a difference of one represents an approximate thirtyfold difference in magnitude.
Explanation:
1. The group nearest the end or with the shortest stem of a phylogenetic tree has evolved most recently. In this case it is eutherians.
2. The group with the longest stem has been around the longest: fish
3. A direct common ancestor will share the same immediate line, like marsupials and eutherians. Fish and marsupials do not have a common direct ancestor.
The number of new cases of a particular disease contracted within a defined population in a specified period is referred to as the incidence of the disease.
Population is defined as a group of similar type of organisms. This group of organisms live in the same area, they require same resources, have similar types of habits. The most essential criteria is that they can breed and reproduce among themselves.
Incidence of a disease is the data that provides information about the number of people affected by a disease at a given period of time. The likelihood of a person getting affected by the disease can be estimated using incidence.
