Which of these groups would most likely to exhibit uniform dispersion?
a .octopus trees, which parasitize particular species of trees
b. cattails, which grow primarily at the edges of lakes and streams
c. bats roosting in caves
d. grasshoppers grazing in a large field

D. Grasshoppers grazing in a large field

Explanation:

In the uniform dispersion the individuals of the population study are spaced evenly throughout the area. This kind of dispersion results from the interaction that occur in between the individuals in which territoriality and competition exists.  

The grasshoppers grazing in a large field is the example of uniform dispersion. This is due to the fact that these organisms will be space more or less evenly over the large field so as to obtain food in the form of small insects which may be distributed over the large grass field.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.
