8) there are several species of grain beetles that live on dry meal and do considerable
damage to stored grain. in an experiment, a dozen jars of dry meal are set up and fifty
individuals of each species, both males and females, are added to each jar. the food
supply is not quite sufficient to last for six months and the size of the jar is adequate so
that wastes do not become toxic. most likely, examination of the jars in six months will
a. a totally random variation in numbers of both beetles.
b. only one species per jar.
c. the same ratio of beetles as when you started (about half from each species).
d. only dead beetles in all jars due to intense competition for the niche.

a. decomposition of organic matter.
b. mechanical weathering of bedrock.
c. chemical weathering of rock.
d. all of the choices are correct.

b. have a special protein on its surface that can interact with a protein on the surface of
the host cell.
c. actively burrow through the cell wall or cell membrane of the host cell to reach the
cell's nucleus.
