Lucy Kerr Question: The data showed that heart rate decreases as the mass of a mammal
1084899
increases. Does this scaling relationship apply as a rule to humans?

Although the general trend is that a

increasing bulk, this scaling relationship

Question: Provide a brief explanation as to why you think the number of Tim Hortons
increases with population size in the way shown by the data.
More schools are generally required to meet the increasing number of
students as a city's population rises in order to ensure enough space to
provide every child/teen with an education. Sub-linearity in the
graph implies there is a slower increase in schools as population size grows.
This could be explained because larger cities may require fewer schools per
population because they have more students per school. For example,
because of their size and resources, schools in larger cities can handle a
higher number of pupils. Population distriubution is another factor affecting
this trent, larger towns can centralize education, whereas smaller cities may
need more scattered schools to serve geographically distributed populations.
