Answer:

Tropomyosin

Explanation:

The calcium binding to troponin and induces the muscle contraction. The active binding site gets exposed due to the calcium binding.

The calcium ions then attaches with troponin molecule. This changes the shape of troponin and removes the tropomyosin protein from the binding site. No ATP is available during this process.

Thus, the correct answer is option (d).

The 'G' in the universal gravitation formula

shutvik [7]

b. Gravitational constant

Explanation:

G in the universal gravitation formula represents the gravitation constant. It's value is 2.071×10⁻⁴³ s²⋅m⁻¹⋅kg⁻¹.

The law of universal gravitation states that "the gravitational force between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance separating them".

Mathematically, the law is expressed as:

F = G $\frac{m_{1} m_{2} }{r^{2} }$
