- Which of the following is NOT a characteristic for bacteria in general? Plasma membrane has no saccharide units Sterols is one of its major outer membrane component Genome present in the nucleiod region of the cytosol Granules are mostly polysaccharide in natureWhich of the following is NOT a characteristic for bacteria in general? a. Plasma membrane has no saccharide units b. Sterols is one of its major outer membrane component c. Genome present in the nucleiod region of the cytosol d. Granules are mostly polysaccharide in natureWhich statement about the cellular arrangments of bacteria is NOT correct? Spiral bacteria are typically single. A diplobacillus arrangement consists of two cocci adhering to one another. A chain of bacilli is called a streptobacillus arrangement. A cube-shaped arrangement of cocci is a sarcina. A square-shaped arrangement of cocci is a tetrad.
- Which of the following is NOT a true statement about bacterial structure and function? A. Bacteria can have membrane-enclosed organelles such as mitochondria or chloroplasts B. Bacteria have a single circular chromosome made of double-stranded DNA C. Bacterial cell walls are made of a substance called peptidoglycan D. Bacterial flagella rotate to propel the cell E. Some bacteria have a capsule surrounding the cell, made of a sticky polysaccharide or proteinWhat feature of mycobacteria is responsible for the unusually slow growth of these bacteria? They have limited numbers of ribosomes so protein production is slow. They cannot fully metabolize carbohydrates and must rely on fermentation. They lack a cell wall and are extremely fragile. The mycolic acid in their cell walls requires signification metabolic investment. Their low tolerance for oxygen retards their growth.Bacteria are classified in which of the following domains? Eukaryote Prokaryote Fungal Plantae
- We put everything in our mouth since our childhood. Therefore our mouth is full of live bacteria. These bacteria are potentially dangerous if they cross our gut wall into our blood circulation. Fortunately we are protected from them by our gut's mucosal lining and the cells (macrophages, dendritic cells, B and T lymphocytes) in the lymphoid tissue called [a] (enter two words). This structure play a crucial role for the development of food tolerance or food [b] (enter one word), coeliac disease and chronic inflammatory bowel disease.Which of the following statement/s is/are true about gram positive bacteria Cell wall has thick peptidoglycan layer Cell wall lipid content is very low Lipopolyscharride layer is absent All of the abovewhat are three cellular parts that are specific to ALL bacteria? This should not include any cellular parts listed that both prokaryotes and eukaryotes will have. This also should not include cellular parts that only specific types of bacteria will have (example: flagella). Then state the function of the cellular part (what does it do for the cell?
