can you answer this biology questions

Explanation:
1) Muscle tissue is a soft tissue that composes muscles in animal bodies, and gives rise to muscles' ability to contract. This is opposed to other components or tissues in muscle such as tendons or perimysium. ... Smooth and cardiac muscle contracts involuntarily, without conscious intervention.
2) 3 Types of Muscle Tissue: The Function of Skeletal, Cardiac, and Smooth Muscle
The Human Body Has Over 600 Skeletal Muscles That Move Bones and Other Structures. ...
The Walls of Many Human Organs Contract and Relax Automatically. ...
Cardiac Muscle Contracts in Response to Signals from the Cardiac Conduction System.
3) The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striated, and are under involuntary control.
4) Striated muscle tissue is a muscle tissue that features repeating functional units called sarcomeres. The presence of sarcomeres manifests as a series of bands visible along the muscle fibers, which is responsible for the striated appearance observed in microscopic images of this tissue. There are two types of striated muscles..
5) Skeletal muscle cells are multinucleated from the fusion of muscle cells. Smooth muscle cells are strictly mononucleated, and cardiac muscle cells are mononucleated in humans. However, cardiac muscle cells are functionally syncytium....
6) The cells, however, are not multinucleated and are not true syncytium (as seen in case of skeletal muscle) but functionally they are syncytium (multinucleated). Therefore, cardiac muscle is functionally multinucleated and skeletal (voluntary) muscle are true multinucleated. So, the correct option is 'Cardiac muscle....
7) The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striated, and are under involuntary control......
8) Visceral Muscle
Visceral muscles are also commonly known as smooth muscle due to their lack of striations. Four characteristics define smooth muscle tissue cells: they are involuntarily controlled, not striated, not branched, and singly nucleated....
9) In summary, skeletal muscles are organs that are directly or indirectly attached to bone. Skeletal muscles serve a variety of functions including support and movement and homeostasis. Skeletal muscle contraction can result in muscle shortening and thus movement of the bone to which it is attached.....
10) Each skeletal muscle fiber is innervated by a single motor axon. The same axon may also innervate other muscle fibers. All the fibers innervated by the same axon are called a motor unit........
