Explanation:
<span>Type 2 alveolar cells or pneumocytes are the cells responsible for secreting pulmonary surfactant. Their function is important as the pulmonary surfactant is required to decrease surface tension within the alveoli. They are capable of cell division which in turn produces more of these alveolar cells when there is damage to the lung.</span>

After the vernal equinox, the most direct rays of the sun striking the earth continue to migrate north. On June 21/22, the most direct rays of the sun fall on locations situated at 23.5 degrees north latitude.
The two proteins directly involved in muscle contraction are MYOSIN AND ACTIN. The interaction between these proteins is responsible for muscle contraction.
The sarcomere is the basic unit of muscle cells (myofibrils) that mediate muscle contraction both in skeletal and cardiac muscle tissue.
During muscle contraction, myosin and actin proteins slide past each other, thereby leading to sarcomere shortening.
The myosin protein binds to actin filaments and thus myosin acts as a motor protein that drives filament sliding.
