PLEASE ANSWE ANSWER My QUESTION
Answers
Answer:
All plants would die
If they don't have microbes to take in and convert important chemical compounds into usable parts, they'll rapidly lose to ability to produce fuel via photosynthesis and will quickly die.
Without microbes, they too would die, and the entire food webs of these dark, abyssal worlds would collapse. Shallower oceans would fare little better. ... Unlike other animals, for whom sterility would mean a quick death, we wouldget by for weeks, months, even years.
Microorganisms present in our body Re viruses, bacteria, fungi, algae, and protozoa among which most of them cause immense benefits to the body. There are some harmful microorganisms too known as pathogens which cause disease and cause a threat to all existing life forms of the earth which can result in death at times.
But as long as humans can't live withoutcarbon, nitrogen, protection from disease and the ability to fully digest their food, they can'tlive without bacteria,”— Anne Maczulak, famous microbiologist. ... Let's learn more about how are bacteria essential for you tosurvive.
Answer:
1) a ) Microorganisms are very small in size. They are so small that they cannot be seen with naked eyes. A microscope has to be used to see these organisms
b) All plants would die
If they don't have microbes to take in and convert important chemical compounds into usable parts, they'll rapidly lose to ability to produce fuel via photosynthesis and will quickly die
c) The existence of microscopic organisms was discovered during the period 1665-83 by two Fellows of The Royal Society, Robert Hooke and Antoni van Leeuwenhoek.
2) a) They have no introns (heterochromatin) in their DNA (genetic materiel). So they are more prone to Mutations, and often these mutations are beneficial for them and help them adapt to changing conditions. 5. They have a number of heat shock proteins which help them thrive in extremes of temperature
b) each human body hosts 10 microorganisms for every human cell, and these microbes contribute to digestion, produce vitamin K, promote development of the immune system, and detoxify harmful chemicals. And, of course, microbes are essential to making many foods we enjoy, such as bread, cheese, and wine.
c) In order to grow successfully, microorganisms must have a supply of water as well as numerous other substances including mineral elements, growth factors, and gas, such as oxygen. Virtually all chemical substances in microorganisms contain carbon in some form, whether they be proteins, fats, carbohydrates, or lipids.
3) a) Microorganisms are divided into seven types: bacteria, archaea, protozoa, algae, fungi, viruses, and multicellular animal parasites ( helminths ).
b) Bacteria (single - bacterium) are some of the most abundant unicellular organisms in the world. ... They are prokaryotic cells, which means that they are simple, unicellular organisms that lack a nucleus and membrane-bound organelles (they have small ribosome)
