A laboratory experiment followed the growth of a flour beetle (Tribolium sp.) population over time. At first, the population increased dramatically, but later the growth slowed and the population size leveled off. Although food (the wheat flour in which they live) was still abundant, the flour beetles resorted to eating their own eggs when population densities got high. What can we conclude about cannibalism in this species?

Explanation:

Cannibalism is a very essential factor regulating population dynamics of four beetle. After some days of feeding, the flour becomes conditioned by the beetles which can affect rate of cannibalism

Adults have a relatively lower rate of cannibalism. While its highest rate of cannibalism is at larvae stage

Flour conditioning is caused by the accumulation of feces, pheromones and ethylquinone- thus is repellent produced by the beetles.

b. read the phase at the intersection of any given temperature and pressure.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
