Final answer:
Dense irregular connective tissue has fibers arranged randomly, providing strength in all directions. It is found in the skin's dermis and arterial walls, providing support and elasticity, respectively.
Step-by-step explanation:
In dense irregular connective tissue, the fibers are arranged randomly, giving the tissue greater strength in all directions and less strength in one particular direction. Dense irregular connective tissue has fibers arranged randomly, providing strength in all directions. It is found in the skin's dermis and arterial walls, providing support and elasticity, respectively.
This type of tissue is found in the dermis of the skin, where it provides strength and support. Additionally, dense irregular connective tissue is also found in arterial walls, where it gives the arteries the ability to stretch and regain their original shape.
