An organism that becomes A) True B) False a successful pathogen must evade detection by the host's immune system 49. There are four (4) generations of tissues found in the seed. A) True B) False 50 Insects became smaller in size when oxygen levels were 50% higher than today's levels. A) True B) False 51. Endospores are heat resistant structures produce by certain bacteria. A) True B) False 52. Biofilms can form on teeth, contact lenses, replaced joints, and in water pipes A) True B) False Match the following: 53. This was the original source of food for theA) Nanoarchaeota picture-winged fruit fly in the Hudson Valley 54. This type of bacteria is linked to skin diseases, 55. This type of bacteria were named according to 56. This term refers to the ability of a bacterial to 57. These are often fatal and are released by living regions respiratory infections, and wound infections. their size. B) Exotoxins C) Hawthorn fruit D) Staphlococcus E) Toxigenicity produce toxins within it's host. bacteria.Explanation / Answer
47. Drought and the metltibg of polar ice caps can occur when the carbon dioxide levels double in the atmosphere is TRUE. Drought can with increasing level of the CO2 with the increased climate change. Increasing CO2 leads to global warming which can lead to melting of the glaciers
48. It is true that the organism that has become a successful pathogen must evade detection by the host's immune system. because if the immune system detects the pathogen then it is surely going to kill that pathogen.
49. it is FALSE that there are 4 generations of the tissue found in the seed. because there are 3 generations that are observes in the seed.
51. it is true that the endospores are the heat resistant structures produced by bacteria.
Endospores are formed in thye unfavourable conditions and make the bateria dormant.l Hewat resistance is caused due to dipicolinic acid.
52. It is true that biofims can be formed on the teeth (dental plaque), contact lenses, replaced joints, and in the water pipes.
53. The original sourse of food for the winged fruitfly in the Hudson Valley is the Hawthorn Fruit.
54. Staphylococcus is the type of bacteria that is linked to the skin diseases, respiratory infections and wound infections.
55. Nanoarchaeota is the type of bacteria that is named according to the size.
56. Toxigenicity is the ability of a bacteria to produce toxins within it's host.
57. Exotoxins are often fatal and are released by the living bacteria.
