**Question:**Thick filaments ______________, but thin filaments do/are not.- are part of the I band- contain actin- contain myosin- are directly attached to the Z disk**Explanation:**This question requires you to choose the correct statement about the characteristics of thick filaments in muscle tissue, contrasting them with thin filaments. Understanding components like the I band, actin, myosin, and the Z disk is essential for answering this question accurately.

In each microfibril, actin thin filaments and myosin thick filaments are organized into a linear…

Answered: Thick filaments are part of the I band…
