What is the larval stage of Taenia sodium called and what animal is this larva normally found in?

Expert Solution

Human cysticercosis is caused by the pork tapeworm Taenia solium. The larval stages of this worm cause the disease in human and pigs. Ingestion of eggs or gravid proglottid that are present in feces of human carriers leads to the infection in pigs and humans. Human are infected when they ingest food contaminated with feces of through autoinfection. Reverse peristalsis carries the gravid proglottids or eggs to the stomach. They hatch to oncospheres in intestine, and invade the wall of the intestine. The oncospheres migrate to striated muscles, brain, liver, and other tissues. Here they develop into cysticerci. The cysts attach to intestinal wall by scolex and then develop into adult tapeworms. The tapeworms then produce proglottids that contain eggs. Each proglottid has around 50,000 eggs.

Cysticerci are the larval stage of this tapeworm Taenia solium. They are small vesicle like sacs that resemble a bladder that is filled with fluid. Scolex is the main body of the larvae. It is normally found in pigs.

Write a class called Animal that contains a static variable called count to keep track of the number of animals created. Your class needs a getter and setter to manage this resource. Create another variable called myCount that is assigned to each animal for each animal to keep track of its own given number. Write a getter and setter to manage the static variable count so that it can be accessed as a class resource

Jean Piaget’s theory based on in cognitive stage during infancy is called sensorimotor stage which he breaks down in six different substages. The first substage is simple reflexes which happens during the first month of life. The example or textbook gives us is the sucking reflex. This reflex causes an infant to suck on anything placed on his or her lips (Feldman, 2015, p. 114-115). Or the infant may start to change the way he/she sucks on the nipple during...
