Microbiology Chapter 1 Microbes
Microbiology - correct answer ✔Study of living things to small to see w/out
magnification
Microorganisms imclude - correct answer ✔- bacteria
- protozoans
- fungi
- helminths-> worms
- algae
- viruses
Viruses - correct answer ✔Are protein coated genetic elements that are not
alive or living
- they are parasitic-> dependent on their host
Microbes - correct answer ✔- they reproduce rapidly
- can't be seen directly
Microbes and the planet - correct answer ✔- bacterial- type been here for =
~3.5 billion years
- only living inhabitants for= 2 billion years
- prokaryotes-> no nucleus
- 1st eukaryotic organisms= ~1.8 billion years
-> they have a true nucleus
- microbes are ubiquitous (found everywhere)
, Evolution - correct answer ✔Accumulation of changes in DNA that occur
while they adopt to there environment
Anoxygenic photosynthesis - correct answer ✔-Without oxygen
Oxygenic photosynthesis - correct answer ✔- oxygen is produced
- allowed for "development" of aerobic respiration(ATP)
Microbes shape out planet - correct answer ✔- main forces that drive the
structure and content of the water, soil, atmosphere
- produce gases such as oxygen, Co2, CH3 (methane)
- enormous underground community of microbes influence soil content and
mineral ectraction
Genetic engineering - correct answer ✔- area of biotechnology that
manipulates the genetics of microbes, plants, and animals for creating New
products and genetic modified organisms
O
Bioremediation - correct answer ✔- the use of microorganisms, either
naturally occurring or artificially introduced to restore stability or clean up toxic
products
-example: " oil spill"
Microbes harming humans - correct answer ✔- majority don't harm humans
- Pathogens-> cause disease
- Emerging-> new disease
( ex: HIV/AIDS)
