Test Your Knowledge on Microorganism -Friend or Foe -Class VIII CBSE

microorganismA microorganism is a very tiny living organism . They are so small that hundreds of thousands of bacteria could fit onto a pinhead.The microorganisms in and on our bodies are protozoa, algae, fungi, bacteria and viruses. Most of them  are beneficial but some are also dangerous.For example, there are microorganisms in our large intestine that synthesis vitamins and allow them to be absorbed into the bloodstream. However, a tiny minority are pathogens (disease-causing agents). These pathogens, often called germs or bugs, are a threat to all life forms.

    I’m writing an essay on how literature and science affect the understanding of humanity and society. I’ve got the literature part down pretty well, but I am absolutely stuck on the science part. I have to choose either between natural sciences or human sciences and relate it to reason, but I don’t have any specific examples. Can you give me a few?

  3. I’m going to do a project based on what type of glue will work the best on different materials. Can anyone help me figure out what category that would fit in, you know, like Behavioral sciences, physical science, botony, ecology, those types of categories. Please, some help!

  7. Religion pre-decides what nature is without much evidence or understanding of what nature is. Whereas science lets the experiments and the equations decide what nature is.

    She’s gonna come out as she is, and science is there to observe her as she is.

    But not religion. It pre-decides what she is. And it’s been demonstrated before that religion has been wrong; and it’ll be wrong again.

    And science is a continuous process. Science is always trying to understand her as she is. But not religion. Religion is stuck on seeing things in only religion’s way. And religion never likes to be corrected.

    Science and religion are incompatable.

  8. give me prof that scientific laws can change!

    Mathematics and computer science are not natural sciences, applied sciences (technology) or social sciences.

  16. It’s purely antecdotal but it feels like the amount of science literacy has gotten worse in recent years. What can we do to reverse that trend? Should we throw money at it? Give incentives to schools that do well in science? Make the standardized tests harder? More scholarships for science majors? Start a new PR campaign that makes science cool? Have the government appoint someone as a Science Ambassador? What do you think would work best?

All known types of organisms can some level of reaction to stimuli, reproduction, development as well as development and homeostasis. A living organism contains one or more cells; when it has one cell it is called a unicellular organism; when it has more than one it is called a multicellular organism.
