Answer: 4. evidence 5. Fact
D. integrins. Explanation: The extracellular matrix comprises a complex framework of proteins and carbohydrates found in the areas outside cells. Collagen proteins, modified with carbohydrates, form collagen fibers that intertwine with proteoglycan complexes consisting of polysaccharides and proteins. This structure is vital for maintaining mechanical strength and structural support for tissues. Integrins, located within the cell membranes, are essential connections between fibers in the extracellular matrix and neighboring cells. They also enable cell communication by detecting both mechanical and chemical signals from the extracellular matrix and triggering intracellular signaling pathways.
Work is defined as being completed when an object shifts as a result of an applied force. It is calculated by multiplying the force exerted by the distance moved as a result of that force. It can be represented as: W = Force x distance
W = 84 J = F (7.0 m)
F = 12 N
I hope this provides clarity.
