The video was stopped every time the gerbils moved into the areas specified above, so researchers were able to note down the time precisely. Males portrayed these behaviours more; therefore this implies that females were more anxious as they showed less of these behaviours.

Fat accumulation in tha adrenal gland: Males spent more time in the inner area than females naturally, but when analysing the results of the outer area females spent a significant of time in the outer area that males Appendix.

In that box there was a square drawn inside, this was called the inner area, and outside that square was called the outer area. When analysed statistically the difference found were significant, as males climbed, sniffed and played with the toy more?.

In this study toy interaction, line crossing and the time spent in the inner area all suggests that the gerbils are explorative and are really relaxed in that environment.

Place the gerbil in your hand or a firm surface such as a table 2. Two standard empty toilet rolls were also tacked down to the floor, one in the outer area and one in the inner area. Concentric whorls of rough endoplasmic reticulum in adrenocortical cells of the mongolian gerbil.
