Aluminium is in Group 3 in the periodic table. Group 3 elements have a 3 valence electrons.
Thus elements like; boron(B), gallium(Ga), indium(In), thalium(Tl) in Group 3 have the same number of valence electrons as aluminium.
Hope it helped!

Answer:
These bundles are also called Fascicles
Explanation:
Skeletal muscle, also called voluntary muscle, in vertebrates, most common of the three types of muscle in the body. Skeletal muscles are attached to bones by tendons, and they produce all the movements of body parts in relation to each other. muscle is a form of striated muscle tissue, which is under the voluntary control of the somatic nervous system. Most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons. A skeletal muscle refers to multiple bundles (fascicles) of cells joined together called muscle fibers.
The bundles of muscle fibers are called fascicles, they are covered by the perimysium. Muscle fibers are covered by the endomysium. Inside each skeletal muscle, muscle fibers are organized into individual bundles, each called a fascicle, by a middle layer of connective tissue called the perimysium.
Answer:
Electron transport chain and ATP synthase
Explanation:
The inner mitochondrial membrane contains an electron transport chain and ATP synthesis. Four membrane protein complexes serve as the electron carriers and are embedded in the inner mitochondrial membrane. These protein complexes are called complex I, II, III and IV. Transfer of electrons from NADH and FADH2 to terminal electron acceptor oxygen occurs via these protein complexes.
During electron transfer, the pumping of protons towards the inner mitochondrial membrane creates an electrochemical gradient. The downhill transfer of protons back to the matrix via proton channel of ATP synthase drives phosphorylation of ADP. Therefore, presence of all the protein complexes of the electron transport chain and ATP synthase is required for electron transfer and ATP synthesis.
