<span> <span> <span> Where,
x₁ = -0.2508
x₂ = 0.0777
x₁x₂ = 0.3058

Inserting the values,
<span><span></span></span>y = 1.15 – {0.251 × (-0.2508)} + {0.078 ×(0.0777)} + {0.306 × (0.3058)}
</span></span></span>
y = 1.15 - (- 0.0629508) + 0.0060606 + 0.935748

y = 1.15 + 0.0629508 + 0.0060606 + 0.935748

y = 1.3125862

german

Answer:

Fermentation is a chemical process that occurs in the cytoplasm since it is anaerobic, that is, with the absence of oxygen.

Explanation:

This anaerobic process is due to the consumption of carbohydrates in the absence of oxygen compared to intense muscular demands such as high-performance physical activity, that is why the obtaining of energy is high, since the purpose is not to anabolize but to catalyze hydrates in order to obtain the energy currency that is ATP and thus produce the contraction of the muscular sarcomero by the union of myosin with actin.
