Final answer:
Ligaments are composed of dense irregular connective tissue, which provides strength and support to connect bones together.
Step-by-step explanation:
Ligaments, which connect bones together and withstand a lot of stress, are composed of dense irregular connective tissue. Dense irregular connective tissue consists of collagenous fibers interwoven into a mesh-like network, providing strength and support. Ligaments are made of this type of tissue, as it allows them to withstand the forces exerted on them during movement.
