Answer: Other children should be observed after the average of 6 weeks from the time of exposure to Carrie who is suspected to be infected by Pin worm.
Explanation:
Pin worm also called enterobiasis vermicularis is a parasitic nematode. The eggs are found in the specimen collected from the perianal skin and in the faeces of an infected individual. In its worldwide distribution, children are more commonly infected than adults. This is so because autoinfection by swallowing infective eggs is common in children. The eggs cause intense irritation and scratching of the infected area leads to the fingers becoming contaminated with eggs. This was observed by Carrie's teacher, as she usually scratch her bottom.
Other children should be observed after the average of 6 weeks from the time of exposure to infective eggs. This is because of the direct life cycle exhibited by the worm. Following ingestion of infective eggs, the larvae hatch in the intestine. Occasionally larvae hatch from the eggs on the perianal skin and migrate back into the intestine where they grow into mature worms. This type of infection is called RETROINFECTION. The larvae develop into fully mature worms in the large intestine. The female worms migrate to the rectum, pass out of the anus and lay their eggs on the perianal skin and perineum. The eggs are produced about 6 weeks after infection. They can remain viable on bedding, clothing, household objects, and in dust for several weeks.
Therefore from the life cycle of the worm, similar problem found in Carrie can be observed in other children after about six weeks of exposure to the infective eggs of the worm.
Answer:
A) Endoplasmic reticulum & golgi apparatus
Explanation:
Endoplasmic reticulumn and Golgi appararus are involved in transportation and modification or synthesis of macromolecules
Example; Insulin enters the Endoplasmic reticulumn in 'proinsuline' (Inactive) form and it is converted to its active form 'Insulin' in Endoplasmic reticulumn . Then it is transported to cytoplasam through Golgi apparatus. On the stimulation of beta cells insulin is secreted out of cell.
It will always epual the same amount of Guanine
