Answer:
The correct answer is - option B.
Explanation:
Greenstick fractures are the type of fractures where one side of the cortex is intact and flexed while the other side is fractured. This type of fracture known as the incomplete fracture,
If any fracture have two or more lines of fracture it is called as Comminuted fractures. Impacted fractures have one segment on other. Due to the performing same activity again and again stress fracture occures that is characterized by failure of one cortical bone.
Thus, the correct answer is option B.
The six most common elements found in living organisms are carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur.
The number of bases is no longer divisible by three. This results in a frame-shift, and all codons from the point of mutation will be affected.
The correct answer is: A. Myofibrils contain thick and thin filaments.
Skeletal muscle cells are called muscle fibers because of their long and cylindrical shape. The plasma membrane of muscle fibers is sarcolemma, the cytoplasm is sarcoplasm, and the smooth endoplasmic reticulum sarcoplasmic reticulum (SR) Sarcoplasmic reticulum is specialized becaused it is involved in the process of contraction, so it stores, releases, and retrieves calcium ions.
The functional unit of a skeletal muscle fiber is the sarcomere which consists of highly organized contractile myofilaments actin that are thin filaments and myosin (thick filaments), together with other support proteins.
