Which statement is incorrect? group of answer choices all of the following are correct muscle cells are surrounded by a branching network of transverse tubules. each muscle fiber is densely packed with myofibrils composed of contractile and elasted proteins. muscle cells are called muscle fibers. the cell membrane of a muscle fiber is the sarcolemma

- All of the following are correct

- Muscle cells are surrounded by a branching network of transverse tubules.

Explanation:

Muscle cells are composed of myofibrils, which are the fundamental and functional parts of a muscle cell. Myofibrils are the ones that are surrounded by a branching network of transverse tubules. These transverse tubules are extensions of the sarcolemma or the muscle cell's membrane. Their distribution and connection to myofibrils allow for the passage of Calcium ions needed for contraction.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

some inherited genetic mutations can be good for the offspring, so the answer is different genetic mutations cause many forms of cancer.
