2. There are more than 70 clinically useful antibiotics, Antibiotics fight pathogenic microbes and cancer cells by interfering with their normal cell processes. In most cases, this interference can occur in one of three ways: prevention of cell wall formation, disruption of the cell membrane, and disruption of chemical processes.
3. The contents of bacterial cells are enclosed in a membrane that is surrounded by a rigid wall that prevents the cells from splitting open. Penicillins and some other antibiotics destroy pathogenic microbes by hindering the formation of this wall. Human cells do not have nor need rigid cell walls and so are not damaged by these antibiotics.
4. Some antibiotics, including nystatin, disrupt the cell membrane of certain microbes. This membrane controls the movement of materials in and out of the cell. If the membrane is disrupted, vital nutrients may escape from the cell, or poisonous substances may enter and kill the cell. But the membranes of human cells are not affected because these antibiotics disrupt cell membranes that contain elements found only in microbial cells.
5. All cells produce proteins and nucleic acids, which are vital to the life of any organism. Some antibiotics fight disease by interfering with the chemical processes by which these substances are produced. For example, streptomycin prevent certain kinds of microbes from producing proteins, and rifampin interferes with the formation of nucleic acids. Human cells produce proteins and nucleic acids in much the same way that microbial cells do. But these processes differ enough so that some antibiotics interfere with chemical activities in microbial cells but not in human cells.
A. Autibiotics destroy pathosenic microbes by preventing the formation of the walls surrounding the membranes of the microbial cells that prevent the cells from split- ting open.
B. More than 70 clinically useful antibiotics have been in- vented to fight pathogenic microbes and cancer cells by interacting with their normal cell processes.
C. Human cells are not surrounded by a membrane
D. Some antibiotics disrupt the cell membrane of certain microbes, letting vital nutrients to escape form. the cell or poisonous substances to enter and kill the cell.
E. Nystatin is used to disrupt the wall surrounding the membrane.
F. Some antibiotics fight disease by interfering with chemical activities in microbial cells but not in human cells.

Every social experience we have affects us in at least some small ways. Family, schooling, peers, and mass media all have an【S1】______on how we are socialized as children. Each of these factors has the power to shape our thoughts, feelings, and actions. The family is the most important because it【S2】______the center of children's lives. Babies are almost totally【S3】______on others, and the responsibility of meeting their needs almost falls on parents and other family members. At least until the start of schooling, the family is responsible for teaching children cultural【S4】______and attitudes. Schooling【S5】______children's social world to include people with backgrounds that differ from their own. Formally, schooling teaches children a wide range of knowledge and skills. School is also most children's first experience with rigid【S6】______. Children are encouraged to conform. to roles and be on time. Another factor that【S7】______children is their peer group. Unlike the family and school, the peer group allows young people to【S8】______from the direct control of adults. Peer groups also give young people the【S9】______to discuss interests that may not be shared by adults. The fourth major influence on social development is the mass media--【S10】______ television. Years before children learn to read, watching television has become a regular habit. Indeed, children spend as much time watching television as they do interacting with their parents.
