Chapter 40, Problem 4SA
Summary Introduction
To determine:
The total worms present after thirty days as 400 were present 30 days ago, and 800 are present under constant conditions.
Introduction:
Exponential growth is the condition that occurs when the number of individuals in a population increases by the same proportion of its total number in each generation. The population growth can be calculated based on the total number of individuals and per capita growth rate.

A man treated his home with a pesticide that kills roaches. The first application of the
pesticide killed 92% of the roaches. Two months later, he applied the same pesticide to
his home again, but the second application killed only 65% of the roaches.
What would best explain the decrease in the effectiveness of the pesticide?
The pesticide is effective only against mature roaches.
The pesticide caused some of the roaches to mutate and metabolize the pesticide.
The pesticide lost its effectiveness over a period of time
The surviving roaches were naturally resistant to the pesticide and that resistance was inherited by their offspring

- Plasmodium is a vector for mosquitos. It is a protozoan that is the causal agent of malaria, which is responsible for killing as many 855,000 people in 2013, the majority of them being children. Populations of mosquitos are strongly influenced by the availability of standing water for egg-laying and larval development. How might mosquito density, and thereby human mortality, be affected by patterns of rainfall?arrow_forward5a.
