actin and myosin
The two rocks that are primarily composed of a mineral that bubbles with acid are limestone and marble.
basalt
basalt
The inner core is solid and composed mostly of iron.
It is mostly molten iron.
thick filaments and thin filaments
Actin & Myosin compose myofibrils.
actin and myosin
sarcomeres are composed of myofilaments
Myofibrils are composed of proteins such as actin, myosin, titin. These proteins are organized into thin filaments and thick filaments, which repeat along the length of the myofibril in sections called sarcomeres.
Cellular cytoplasm is primarily composed of lipids.
The is no known planet composed primarily of Iron Oxide.
Myofibrils are thread like structures found in muscle fiber composed of bundles of myofilaments.
Gas (primarily hydrogen)
Thin filaments consist primarily of the protein actin, coiled with nebulin filaments. Thick filaments consist primarily of the protein myosin, held in place by tit in filaments.
There are three components.They are micro filaments,micro tubules and intermediate filaments.All are composed of proteins.
