| 1998463541 | Acquired Immunodeficiency Syndrome (AIDS) | Since 1981.Disorder of the immune system caused by a human immunodeficiency virus (HIV), a retrovirus that destroys the body's ability to fight infection. As the disease progresses, the individual becomes overcome by disorders, including cancers and opportunistic infections. There is no known cure. | 16 | |
| 1998463542 | West Nile Fever | A viral infection affecting birds, horses and humans that cause fever, headache, enlarged lymph nodes, and possible brain inflammation. In USA 1999. | 17 | |

| 1998463546 | Ebola | A contagious viral disease originating in Africa. It is transmitted by blood and body fluids and causes body organs and vessels to leak blood, usually resulting in death. | 21 | |
| 1998463547 | Viroid | Smaller than a virus. Strands or circles of RNA. Cause many plant diseases. Affects citrus and potatoes. Discovered in 1971. Pieces of 'naked RNA'. | 22 | |
| 1998463548 | Prokaryote Structure | No nucleus, no membrane-bound organelles. Bacteria are abundant. Ribosomes in cytoplasm. Some may have semi-rigid cell wall. DNA in nucleoid. | 23 | |
| 1998463549 | Nucleoid | A dense region of DNA in a prokaryotic cell. | 24 | |
| 1998463550 | Eubacteria | Kingdom of unicellular prokaryotes whose cell walls are made up of peptidoglycan. Cant survive in as extreme environments. Most standard energy production. | 25 | |
| 1998463551 | Archaebacteria | A group of microorganisms whose cell walls do not contain peptidoglycan and that typically live in extremely harsh environments. Less standard energy production. | 26 | |
| 1998463552 | Similarities between Eubacteria and Archaebacteria | No nucleus, no organelles, and evoked from common ancestors. | 27 | |
| 1998463553 | Binary Fusion | Type of asexual reproduction in which an organism replicates its DNA and divides in half, producing two identical daughter cells. | 28 | |
| 1998463554 | Conjugation | A form of genetic recombination in bacteria in which plasmid and/or genomic DNA is transferred from one bacterium to the other through a conjugation bridge. | 29 | |
| 1998463555 | Plasma | Small circles of extra DNA with only few genes and self replicating. Resistance to antibiotics. Helps in bacterial conjugation. | 30 | |
| 1998463556 | Cocci | Round shaped. | 31 | |
