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 C.
Plants use atmospheric CO2 through photosynthesis
Answer:
Concentration gradient.
Explanation:
Diffusion may be defined as the process of the movement of solute particles down the concentration gradient. This process does not require the expenditure of energy.
The main driving force in diffusion is the concentration gradient. The molecules generally move from its region of the higher concentration towards the region its lower concentration.
Thus, the correct answer is option (3).
<span>Electron microscopes therefore allow for the visualization of structures that would normally be not visible by optical microscopy. Light microscopes are not able to see things in a larger magnification compared to electron microscopes. Also you're able to see in 3d in electron microscopes and you can't see in 3dimentsional in light microscopes.
