1) Psychrop hiles Mirobes that live in cold environments like sea ice and the arctic and antarcticice packs. 2) Thermop hiles Microbes that live in very hot environments like deep sea vents and volcaniclakes. 3) Alkalip hiles Microbes that live in basic environments like soda lakes. 5) Acidop hiles Microbes that live in acidic environments like sulphur springs. 4) Halop hiles Microbes that live in very salty environments like salt lakes and salt mines. pose the type of extremophile you're most likely to discover in these inhospitable locations. v In the interior lo at 30OK v At the bottom of the Europa ocean v In the cloud layers of a Hot Jupiter v In the core of a nuclear reactor v Martial polar cap v In the upper cloud layers of Venus

Explain 4 approaches to preventing or limiting biofilms.

What are these organisms?

Measurements taken at a lake in Kenya have a pH level of 10.5, temperature of 305 K and salinity of 32%. Which two groups of extremophiles might be found in this lake? What adaptions might be required to survive in this lake?

Why are large parasitic worms included in studies of microbes? All parasitic organisms are classified as microbes.   They always live in symbiotic relationships with other microbes.   They do not share a common ancestor with other animal groups.   Their life cycle resembles that of protozoans.   Proper identification of them often involves an analysis of microscopic eggs and larvae.

Explain what is happening with this graph that charts the reactions ofa mesophilic bacterium to temperature. Blue shows the survival curveand brown the growth curve under various temperatures.

After some time, you found out that you did not like working in microbiology lab, so you found a job at an Environmental lab. Some park attendants said that their dogs took a dive in one of the park’s ponds and after few days they became sick. So, you went to the park and took a sample of the water to analyze it 14) Name the disease or sickness they cause in humans15) Name the phenomenon they are responsible for in marine habitats16) What do these organisms use for movement?17) If these organisms reproduce at a high rate, what will happen to the other aquatic life forms living in the pond? Why

1)describe how you can use an ‘agar deep’ to learn more about an unknown microbe. These are sometimes also called ‘semi-solid deeps’.

Mycobacterium tuberculosis infects the upper regions of the lungs. This bacteria is classified as a(n)___.     aerobe     thermophile     saprophyte     anaerobe

Biofilms are often formed on artificial surfaces in the human body. During medical procedures, when artificial joints, intravenous catheters, urinary catheters are placed and injections are made, commensals/mutualists may be introduced into new sites in the body and there they may form biofilms. Which statement below is NOT a reason to explain why such bacteria living in biofilms are so difficult to eliminate? O layers of biofilm prevent phagocytes from killing bacteria O layers of biofilm acts a a diffusion barrier against antibiotics O biofilm stimulates bacteria to grow continually in the log/exponential phase of growth O layers of biofilm acts a a diffusion barrier against antibodies/immunoglobulins O bacteria often in stationary phase of growth
