Correct Answer: B. The rough endoplasmic reticulum has many ribosomes bound to its surface, but the smooth endoplasmic reticulum does not.

Explanation

The rough endoplasmic reticulum is described as rough because it is covered in ribosomes, which look like tiny beads along its surface. The smooth endoplasmic reticulum doesn't have these ribosomes all over its surface, so it appears flat and is described as smooth for this reason. The ribosomes function to make proteins.

Ralph and Piggy are the first two boys to appear on the island after a plane conveying them to safety has been attacked. Piggy reveals to Ralph in this first encounter that he has been wearing spectacles since he was three. In many respects Piggy is both physically and health-wise a weak boy. He has asthma so he has been warned by his guardian not to run; and he wears spectacles because he has sight challenges.

Piggy's glasses are one of the symbols in the novel which are significant to the meaning of the novel. Apart from the conch, the glasses appear to be the next most significant symbol which bear directly on the survival strategies of the boys. After the boys have settled on the issue of the need to have a Chief and the use of the conch as a symbol of authority, the next challenge confronting them is the issue of rescue. This challenge is projected to be addressed by setting up a fire on top of the mountain. Piggy's glasses becomes the useful tool to light the pile of wood for this purpose. Jack instantly points to the glasses and there is a general agreement by the boys. Both Jac and Ralph jointly use the glasses to light the fire.

The general enthusiasm which greets the setting up of the fire is shortlived as Jack and his group fail to watch over it. He leads his hunters on hunting adventures and the fire dies down, which makes the dream of rescue to fail when a ship passes by on the sea. However, Ralph leads Piggy and Samneric to re-light the fire. Again Piggy's glasses are used to reenliven the boys' rescue attempts. Even though Jack is not so much concerned about the fire at this point, the significance of the fire is underscored by the equally important glasses.

Unfortunately, the glasses are stolen by Jack's group in a raid they carry out on the shelter where Ralph, Piggy and Samneric are now camping. Here the glasses are significant in two respects. First is their importance to the tribe. The hunters realize once again that much of their survival depends on having a fire with which they can roast meat and light their part of the island. Second is its significance to the plot. The event of stealing the glasses signifies the beginning of the events that culminate in the final peace and order on the island. Piggy's glasses are partially broken at this point. The attempt to recover the glasses leads to the climax of the story. Jack captures Samneric and engages Ralph in a physical fight. Finally a rock falls and kills Piggy, destroying the conch and breaking the glasses.

Thus, the glasses are not only a symbol of Piggy's weakness as a character but also significant to the development of the plot of the novel.

Explanation

The causes of violence in the novel. Violence has been a major feature of the American society since the advent of the Blackman in America. Richard Wright's Black Boy gives a detailed and largely faithful expression to the phenomenon of violence in that society. Violence, as portrayed in Black Boy, emanated from three principal sources. These are racial discrimination, quest for dominance and domestic tension. Racial discrimination in the novel is manifested whenever instances of brutality, segregation and injustice are meted out against blacks on account of their colour. There is enough evidence in Black Boy that Whites brutalise Blacks under the idea that the latter are sub-human and so do not deserve any humane treatment. Instances of brutality leading to violence are as follows:

(a) Avenues for employment are closed to blacks. They are therefore confined to menial jobs and reduced to poverty. They therefore resort to petty thievery and violence against each other. Indeed a white boss becomes surprised when a black employee is not for longtime discovered to have stolen something. This is a major cause of white violence against blacks.

(b) The White man in the American society appears to be convinced that the Black man is sub-human and does not deserve to be treated as human. The blacks are therefore continually the victims of violence from whites. Richard Wright is hit with a bottle between his eyes because he failed to address a white man "sir". Richard does not receive any treatment from his white boss when the boss's dog bites him because "dog bite no harm nigger". These and other incidents lead to violence.

(c) The Richard-Harrison fight is another evidence of racial discrimination. The white push them to maul each other to satisfy their sadistic tendencies while the poor black boys suffer.

The quest for dominance among blacks is also another source of violence. Here, reference may be made to the street children who attack Richard, beating him and snatching his money from him. The money was given to him for shopping. The mother sends him back mainly to fight back and secure his right to Memphis streets. After fighting and defeating the boys, he declares that he has indeed acquired his right to the streets.

A third source of violence is the domestic tension always unfolding in Richard's home. There is, first of all the frequent beatings Richard's mother receives in the hands of the father. This breeds a sort of tension in Richard which always threatens to break out.

The fight between Richard and Aunt Addie over religious differences and which spilled over to the school is also the result of the domestic tension going on all the time.

The killing of the kitten meant to embarrass the father is also a kind of violence in the home. There is also the setting ablaze of the house which is also evidence of violence.
