Explanation:
In plant anatomy, tissues are categorized broadly into three tissue systems: the epidermis, the ground tissue, and the vascular tissue. Epidermis - Cells forming the outer surface of the leaves and of the young plant body. Vascular tissue - The primary components of vascular tissue are the xylem and phloem.
Answer:
The correct order in which light passes through the structures of the eye is cornea → pupil → lens → vitreous humor
Explanation:
Light and images are the stimuli that must be perceived by the eye for the sense of vision to be produced. These stimuli must go through some ocular structures before reaching the retinal photoreceptors, passing to the optic nerve and being conducted to the brain.
The order of ocular structures that light passes through before reaching the retina is
- <em><u>Cornea</u></em><em>, the outermost layer of the eye that covers the iris.</em>
- <em><u>Pupil</u></em><em>, which corresponds to the opening in the iris that regulates the passage of light.</em>
- <em><u>Lens</u></em><em>, which is the transparent structure that is found in the anterior chamber of the eye and allows focusing.</em>
- <em>The </em><em><u>vitreous humor</u></em><em> is a substance with gel consistency that is behind the lens and separates it from the retina.</em>
The correct ocular function, with respect to vision, depends on the integrity of all structures through which light must pass before reaching the retina.
Answer:
Physical dependence
Explanation:
Physical dependence is a physiological condition in which continuous use of a drug makes the brain to adapt and develop tolerance against the effect of the drug, and as a result, the body would require continuous use of that drug to maintain the positive effect the individual gets from using such drugs. A withdrawal from the use of the drug by the individual would bring about uncomfortable and unpleasant withdrawal symptoms. Misuse of drugs such as opioids, amphetamines etc can result in physical dependence.
