<span>Assists in the accommodation of light from the external environment that penetrates thru our pupil and proceeds in our lens.
Evolutionarily, the eye structure was designed to be at the head specfically superior to the nose, posterior to the skill and distal to the brain and is anteriorly plastered to avoid environmental threats like predators, natural disasters and etc. This way in a functionalist view, the eye has a wider range in getting information from one's environment especially in humans since the eyes in people are the most efficient and powerful sensory organs than the others. In a structural view, the eyes are build in two not only to be able to see one's environment and maximise it but also because the eyes have binocular disparity this means that the eyes will be able to locate an object more cearly and that when one eye is dysfunctional the other can assist the visual imagery of the individual.<span>

Answer;
Xylem;
if you cut a stalk of celery and put it in a glass of water containing red food coloring overnight, the next morning the celery will be red. This has occurred because the xylem has conducted the colored water up through the stalks.
Explanation;
-Xylem is a vascular tissue that transports water and minerals from the roots to other plant parts; consists of long, narrow cells called tracheids and wide, barrel-shaped cells called vessel elements; tracheid-conducts water and minerals through pits; vessel element- conducts water and minerals through pits and perforated end walls.
Answer:
Quorum sensing is triggered to begin when<u> a sufficient number of bacteria are present .</u>
Explanation:
Quorum sensing -
Quorum sensing is the ability to detect and to respond to the cell population density by the process of gene regulation . Quorum sensing bacteria releases some chemical signal molecules called the autoinducers , that increases the concentration as the function of the cell density .
The detection of the minimum threshold concentration of an autoinducer leads to the alteration in the gene expression .
The answer is D wrist joint
