Question

they contain muscle tissue that can contract to shorten, or flex, the hamstrings. nervous tissue in the hamstrings tells the muscle tissue when to contract and relax. the hamstrings have connective tissue to bind them to blood vessels and nerves, and to attach them to the back of bones in the lower leg. so, when the hamstrings flex, they pull the bones and cause the lower leg to bend at the knee joint. select evidence that supports the claim that tissues within an organ work together. without connective tissue, the leg would not bend at the knee joint when the muscle tissue contracts. without nervous tissue, muscle tissue in the hamstrings would not receive the signal to contract. the connective tissue that surrounds individual muscle fibers is called endomysium, while the connective tissue that surrounds the entire hamstring is called epimysium. connective tissue binds blood vessels to the hamstrings, which provides muscle tissue with the blood supply it needs to expand and contract.

Explanation:

• The first option shows that connective tissue is necessary for the leg to bend when muscle tissue contracts, indicating cooperation between tissues.
• The second option indicates that nervous tissue is needed to signal muscle tissue to contract, showing tissue - to - tissue interaction.
• The fourth option shows that connective tissue helps in providing blood supply to muscle tissue, which is essential for muscle function, demonstrating tissue cooperation.
• The third option only describes the types of connective tissue (endomysium and epimysium) and does not show how tissues work together.

Answer:

• "Without connective tissue, the leg would not bend at the knee joint when the muscle tissue contracts."
• "Without nervous tissue, muscle tissue in the hamstrings would not receive the signal to contract."
• "Connective tissue binds blood vessels to the hamstrings, which provides muscle tissue with the blood supply it needs to expand and contract."
