When you are in the resistance stage of stress your body is what damage caused in the alarm stage?
Savatey [412]
I think the correct term to complete the thought of the sentence would be "repairing". When you are in the resistance stage of stress, your body is repairing the damage caused in the alarm stage. The resistance stage is a coping mechanism of the brain to be able to cope up with the stress. The body would start to crave or ask for something in order to keep up with the stress. In this stage, blood pressure and hormones are being regulated like cortisol and adrenaline. They may be in high level than the normal but only to a level that is slightly higher. However, this stage does not fully get rid of the stress.

Answer: lack of plant diversity

A deciduous forest is a biome that is occupied with deciduous trees which shed their leaves seasonally. The leaves are typically broad and wide. The deciduous forests are known for plants of coniferous genera such as Metasequonia and Larch. Other faunal variety includes elm, birch, aspen,  honeysuckle, maple and oak.

Although the tree species is maintained by replanting but the diversity of plant species cannot be maintained. If a particular tree species is used by animals to obtain it as shelter, food and for other needs, cannot be found in the replanted area animals might not return back.
