<span>Within the composition of stars, there are a number of distinct zones with different regimes of behavior. In the case of the Sun, the temperature profile listed above equates to that of the radiation zone, where the temperature falls over 5 million degrees Celsius. Thus the answer is B. radiation zone.</span>

The inner ear structures containing granules and helps with gravitational equilibrium are: the semicircular canals called utricle and saccule.
Ear is the organ involved in the hearing of sounds and also maintains the balance of the body. The ear is distinguished into three parts: the outer ear, the middle ear and the inner ear. The outer ear is called pinna. The middle ear consists of three most important bones called the malleus, incus and stapes.
Semicircular canals are the parts involved in balancing. These are the tiny tube like structures that contains a fluid. Apart from balancing, the semicircular canals are also able to detect the head position.

<span>Since muscle contraction depends on interactions between actin, myosion and some intermediate molecules, the primary protein structure of such proteins and their spatial conformation are fundamental for their functioning. For example, actin and myosin, both filamentous proteins that slide past each other or troponin/tropomyosin interactions that blocks the binding of myosin to actin.</span>
