Answer:
The correct answer is myofibrils
Explanation:
The fundamental part of the muscle cytoskeleton is made up of myofibrils that are the contractile elements of skeletal muscle cells.Muscle fibers are made up of myofibrils, membranes, and cytoskeletal networks that anchor contractile fibrils to the sarcolemma. Myofibrils are composed of repeating contractile units known as sarcomeres and are perhaps the most ordered macromolecular structures in eukaryotic cells. Myofibrils are made up of actin and myosin filaments that are large polymerized protein molecules responsible for actual muscle contraction.
Answer:
B
Explanation:
Water moves from higher potential to lower potential i.e it moves from surounding to the cell.
Answer:
to contract a muscle, myosin and actin filaments shorten, requiring ATP binding and hydrolysis
Explanation:

Answer:
The correct answer is option D. cube.
Explanation:
The image represent the cells similar to the epithelial cells whcih is found in various tissues such as muscle, nervous and many more. These cells are found in cuboidal, columnar and squamous sha[es which found in normally double layer or in multiple layers.
These cells are cube like in structure with a spherical nucleus present in the center of the cell known in assocation of various cells.
Answer:
Ribosomes.
Explanation:
The function of ribosomes is to make protiens by joining amino acids together.
