Answer:
The endosymbiotic theory
Explanation:
Protists are the multicellular organisms which possess characteristics of both the prokaryotes and eukaryotes.
The protist can derive nutrition by either heterotrophic mode or photoautotrophic mode. This variation could exist within the same genus and same species.
This variation could be explained with the endosymbiotic origin of the organisms as some species could engulf the photosynthetic bacteria whereas some could have engulfed the chemosynthetic bacteria.
This can be observed in the green and red algae which depend on a different mode of nutrition belonging to the same group.
Thus, the endosymbiotic theory is correct.
The interpretation of bodily pain and touch also involves the parietal lobe.
<h3>What area of the brain is responsible for controlling movement and pain perception?</h3>
The eyes, face, and mouth may all move thanks to the brainstem. Additionally, it sends sensory information (such hot, painful, and noisy) and regulates breathing, awareness, heart function, and uncontrollable muscular movements like sneezing, coughing, vomiting, and swallowing. Cerebellum. This area of the brain is the back.
<h3>The brain's mechanism for detecting touch?</h3>
Sensitivity to touch and cortical maps
Initial impulses from sensations are produced by touch receptors in your skin. They move along sensory nerves made of bundled fibers that are linked to spinal cord neurons. After that, information is transmitted to the thalamus, which in turn informs the rest of the brain.

Answer is stretch receptors.
Stretch receptors respond to the distention of muscle wall of the bladder and are neurologically linked to the medulla. Stretch receptors in the bladder signal the parasympathetic nervous system to stimulate muscarine receptors, present in the detrusor muscle, to make him contract. This leads to the expulsion of urine.
