Members of Protista kingdom contain multi-celled organisms such as kelp and single-celled organisms such as Paramecia.

Paramecia are unicellular ciliated protozoan. They are widespread in freshwater, brackish, and marine environments. They are abundant and stagnant in basins and ponds.

The answer is Paramecium.

The Protista kingdom contains eukaryotic organisms that do not belong to the Kingdoms of Fungi, Plantae or Animalia. These organisms could be multicelled or single-celled. Some multicelled organisms of this kingdom are kelp, slime molds, red algae. Among unicelled protozoans, the best known is Paramecium.

What are the steps in filament theory
Inessa [10]

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.
