Answer and Explanation:
The steps of the sliding filament theory are:
Muscle activation: breakdown of energy (ATP) by myosin.
Before contraction begins, myosin is only associated with a molecule of energy (ATP), which myosin breaks down into its component molecules (ADP + P) causing myosin to change shape.
Muscle contraction: cross-bridge formation
The shape change allows myosin to bind an adjacent actin, creating a cross-bridge.
Recharging: power (pulling) stroke
The cross-bridge formation causes myosin to release ADP+P, change shape, and to pull (slide) actin closer to the center of the myosin molecule.
Relaxaction: cross-bridge detachment
The completion of the pulling stroke further changes the shape of myosin. This allows myosin and ATP to bind, which causes myosin to release actin, destroying the cross-bridge. The cycle is now ready to begin again.
The repeated cycling through these steps generates force (i.e., step 2: cross-bridge formation) and changes in muscle length (i.e., step 3: power stroke), which are necessary to muscle contraction.

<h3><u>Turmeric powder can be adulterated in many different ways:</u></h3>
- Curcuma longa(Turmeric) is a strong base and is used as a domestic product.
<u>The possible adulteration and deterioration of Curcuma longa are as follows</u>:
- It can be mixed with chalk powder which results in production of small bubbles.
- When turmeric powder is mixed with water, it produces some streaks of soluble colour in water that is caused as a result of adulteration of lead chromate in turmeric powder.
