human gut and thinglink.

Assalamualaikum and hai! as for this week, we are doing flipped classroom again on human gut. this topic is kind of interesting where I can get to know what is the microorganism that are pathogen or non-pathogen to our body. the group that responsible on doing the flipped classroom is doing the good job, they used all the tools to deliver the knowledge for us, not forgetting the atmosphere group also done a very good job as they are doing the powtoon, and I really thought that the video is from the internet as it is really excellent video. for me for this week, the class is happening as always, and I love to study in that kind of environment. but it is early in the morning, our brain is still in sleep mood. haha, but with the laughter and all the interaction between the lecturer and student makes me awake. and here, I'll attach the link to my thinglink, I have selected the photo that I have taken myself, It is at Cameron Highland, on the MARDI i guess. and yaaa have a look. :)

microorganisms in plant. (thinglink)


microbes in soil. (thinglink)

there are 3 types of bacteria found in soil. which are :
1) decomposer
- Bacillus subtilis.




  • Bacillus subtilis, known also as the hay bacillus or grass bacillus, is a Gram positive, found in soil and the gastrointestinal tract of ruminants and humans.B. subtilis is rod-shaped, and can form a tough, protective endospore, allowing it to tolerate extreme environmental conditions.
  • as an immunostimulatory aid in the treatment of gut and urinary tract diseases such as Rotavirus and Shigella
Pseudomonas fluorescens



  • P. fluorescens has multiple flagella. It has an extremely versatile metabolism, and can be found in the soil and in water
  • useful in treating skin, ear, and eye disorders

2) Nitrogen fixer.


  • The bacteria colonize plant cells within root nodules; here the bacteria convert atmospheric nitrogen to ammonia and then provide organic nitrogenous compounds such as glutamine or ureides to the plant. The plant provides the bacteria with organic compounds made by photosynthesis.
3)Actinomycetes


  • Actinomycetes are a specific group as bacteria.
  • Morphologically they resemble fungi because of their elongated cells that branch into filaments or hyphae
Some thermophilic and thermotolerant actinomycetes are found to be responsible for allergic symptoms in the respiratory tract

fungi.

Mycorrhizal fungi are a remarkable group of organisms that have been benefiting plants for at least 500 million years.
At the dawn of time when plants were just beginning to colonise our planet mycorrhizal fungi were there living in a symbiotic relationship with plants enabling them to extract nutrients and hold onto water in very difficult soil conditions.

microbes in freshwater (thinglink)

The two protozoa that mostly found in water are Giardia and Cryptosporidium
Giardia and Cryptosporidium form dormant and hardy forms called cysts during their life cycles. The cyst forms are resistant to chlorine, which is the most popular form of drinking water disinfection, and can pass through the filters used in many water treatments plants. If ingested in drinking water they can cause debilitating and prolonged diarrhea in humans, and can be life threatening to those people with impaired immune systems.
Giardia


Cryptosporidium

E.coli

And here is the video, to the amazing world of the water microorganisms . have a look :)

hydrosphere.

as for this week, it is for our turn to do the flipped classroom. we have done popplet, thinglink and cross word puzzle by kubbu. i have also already inserted the info regarding the hydrosphere topic to my blog. I think that, my classmate understand what we are trying to deliver. and I hope what that we have done, give benefits to them. for the next class, we have been given the quiz upon the hydrosphere topic. As a student, I understand that we should be able to answer the question given by the lecturer, but I just can't easily recall back what that I have learn, as I am a slow learner. but, I'm trying my best to answer all the question that were given.

for hydrosphere topic, I really enjoyed learn it, as I am put extra effort to dig in the info, to be shared to all of my classmate. actually, we have learned about the river and lake zonation in matriculation, but it is slightly different as, we learned about the microorganisms that live in it. oh by the way, im updating my blog at my kampung, Perak!! so the connection is like too slow, and for sure I'll enjoying the view here. ;)
and here is the link to my explanation about the river anatomy

lithosphere

lithosphere, is one of the most abundance living thing live in it. including us human. so for this week we learn about the lithosphere. and the most interesting thing is, we do it like flipped classroom. from my opinion, through this kind of learning, it give so much benefits as the one that conducted the flipped classroom is the student itself, so for sure the one that conduct it will understand more. for us, who are participating in it we got to learn new thing, like voice thread that has been conducted by the group 4. they did such a good job together.

and yea for sure, we have done popplet to do the research on microorganism that live in the bedrock(cave). because, i think that is the most suitable medium for me and other team members to do work together.
