Red tide is a common name for algal blooms, which are large concentrations of aquatic microorganisms, such as protozoans and unicellular algae (e.g. dinoflagellates and diatoms). The upwelling of nutrients from the sea floor, often following massive storms, provides for the algae and triggers bloom events.
Answer:
The correct answer is: a. directs somatic motor axons to four of the six extrinsic eye muscles and also transmits parasympathetic visceromotor impulses to pupillary constrictor muscle of the eye.
Explanation:
<u>The </u><u>oculomotor nerve </u><u>(III) is the third cranial nerve.</u> It provides motor innervation to four of the six extrinsic muscles of the eye and has also a parasympathetic component in charge of contracting the pupil when the environment is rich in light.
The cranial nerve that innervates the lateral rectus muscles of the eye is the abducens nerve (VI).
The cranial nerve that provides motor innervation to the superior oblique muscle of the eye is the trochlear nerve (IV).
The answer is microevolution
