And now finally my turn for Pecha Kucha. My hands feets head ears stomach all was cold because I was so nervous. I do not know if I have done my best for my Pecha Kucha. I was too nervous and that make my mind become blank but luckily I have done it. Im talking about my microbe that I have adopt. This little guy name is Deinococcus Radiodurans

# data[].attributes.body
This week was quite a tough week. So, some of us have done the Pecha Kucha on the afternoon. We can see everyone were so nervous haha. As I watched my classmates presented their microbes, I learned many new kind of microbes that are very interesting. And at 3, we start to learn about microbial growth. We have done the mind map so it is easier for us to learn.

# data[].attributes.body
For week 12, we have discussed about our newsletter, next semester plan, our pecha kucha and other things that I cannot even remember because they are so many things that keep coming to my head with all of the presentations, assignment and all. And we also learn about sterilization and disinfectants. You can learn the difference between antiseptics, disinfectants and sterilization

Ways to Defend Against Infection

Whether you are going in for surgery or are just cleaning your house, there are all sorts of different ways by which you can try to kill potentially deadly bacteria, viruses, and other harmful pathogens. Three of these ways are antisepsis, disinfectants and sterilization.

These three different techniques are super important in keeping a clean home or in preventing potentially deadly infections during surgery. We'll see how these two seemingly different actions, cleaning the house and surgery, may actually overlap.

Disinfection

In the doctor's office, or at home, someone almost certainly performed a task called disinfection. Disinfection is the process of destroying and eliminating almost all of the microorganisms on inanimate objects and surfaces.

If that definition confused you then don't worry. I am 99.9% sure you intrinsically know what this actually means. For, if you've ever seen a commercial touting that a certain spray kills 99.9% of germs, then you were dealing with something called a disinfectant.

This disinfectant is sprayed on inanimate, or non-living, objects, such as windows, your kitchen's countertops, and the cabinets in a doctor's office, to eliminate virtually all living microorganisms on that object or surface.

The key thing to remember is that disinfectants do not eliminate all microorganisms and are used on inanimate, or non-living, objects. Furthermore, the amount and type of microorganism killed not only depends on the kind of organisms being targeted, such as a bacteria, viruses, or fungi, but also the type of disinfectant used.

That's because not all disinfectants can get every type of microorganism, and even the best disinfectants may not work very well if the temperature isn't just right, the concentration of the disinfectant is off, or there is a lot of dirt on the surface of the object that must be penetrated.

That's why prior to disinfecting something like a toy that was lying around outside, it's important to clean off any dirt and debris you can see with your naked eye prior to using a disinfectant that kills the microorganisms that you cannot see. Other factors, such as the type of surface being disinfected, the length of time the disinfectant is used for, and the way the disinfectant is applied may also influence its effectiveness.

As a morbid metaphor, you can compare the effectiveness of a disinfectant on a certain microorganism to the way a murderer (the disinfectant) may try to kill a person (the microorganism). For example, someone may try to kill a person by dropping them into the sea, far from shore, in the hopes that the person will drown. But if that person is a good swimmer, then that method of killing won't be as effective as frying that person to death instead. That's why you have to be careful in which disinfectant you use to kill a certain type of microorganism.

Finally, some disinfectants kill microorganisms outright while others simply inhibit their growth. If a disinfectant ends in the suffix -cidal, such as bactericidal, then it kills that type of microorganism. However, if it ends in the term -static, such as bacteriostatic, then it inhibits the growth of that microorganism. In the case of the latter, the bacteria will eventually die due to something like old age, and because they couldn't have children, theoretically no more bacteria should be left after a certain period of time.

Sterilization

In any case, disinfection is in slight contrast to something known as sterilization. Sterilization is the destruction of all microorganisms on an inanimate surface or object. As you can tell, both sterilization and disinfection work on inanimate objects or surfaces. However, sterilization gets all, as opposed to most, microorganisms. It's unequivocal. It's either all or nothing.

Therefore, it's highly unlikely that you went ahead and sterilized something like your kitchen countertop. This would be very difficult, expensive, and dangerous to do unless you are very well trained and have a lot of nifty chemicals or equipment.

However, sterilization is very important in places like a hospital, where a doctor or surgeon will need to use surgical instruments for a certain procedure. These surgical instruments must be sterile prior to use. That's because if they have even one little microorganism on it and that microorganism jumps off of the surgical instrument and into the cut the surgeon makes into your body, you can get a life-threatening infection!

The most common way by which objects, such as surgical instruments, are sterilized is through a process known as autoclaving. This is a procedure that uses steam under pressure, to destroy all living microorganisms on inanimate objects and surfaces.

We going through week 11 learning about virus. Everytime I see virus, I will see a small evil creature because many movies I have watched, the virus always on the evil side. I do not know, that just how I see virus before I learned about it. But now of course I find this virus are very interesting but still they are bad people.

Okay for this week, on Wednesday, me and my group together went to the Science
Exhibition held in the Dewan Besar. We had interviewed some Ph.D students and lecturers and I am really impressed and wondering how can they can even came up with all those brilliant ideas and researches. On Friday, each group bring a laptop and we have to do padlet but our group have a problem with the wifi but its okay we had overcome it so chill ya . Overall, its a good week for me. Everything still under control.

HELLO EVERYONE !! i felt so good because we just came back from our mid sem break. it was do much fun and im already felt homesick i miss everthing lol. But chill, we've got microbiolgy class . Always lots of fun . So, this week we learned about protist. Many new things that I learned about protist from Dr. Wan Zuhainis. Below, i shared a video about protist. it is actually about a student who make a rap song about protist soooo enjoyyyyyy

# data[].attributes.body
This week we had a class at the computer room. Dr.Wan have gives us a tasks to do notes for protists. My group do the mind map which most of us learn by using this technique. So, we divided our parts and everybody do their own  parts successfully.

Definition

When you examine the kingdom protista you might think you have been carried away to a strange land filled with strange creatures. Algae, amoebas, and slime molds, oh my! But despite all belonging to the same kingdom, these organisms have little in common. They look different, move by different means, and feed in different ways. They don't fit into any other group because they are not animals, plants, bacteria, or fungi. We call these leftovers of the living world the protists.

As different as protists may be, they all have to reproduce. This lesson will discuss how protists create new protists through both asexual reproduction and sexual reproduction.

Asexual Reproduction

Asexual reproduction requires one parent and produces offspring that are genetically identical to that parent. In addition to the convenience of self-reproduction, asexual reproduction can occur more frequently and produce rapid population growth. Because of this, asexual reproduction is the primary method protists use to reproduce.

The following are types of asexual reproduction that occur in protists:

Binary fission: Binary fission occurs when a single protist divides its nucleus and then divides itself into two separate organisms.

Multiple fission: Multiple fission is similar to binary fission, except the nucleus can divide and form many daughter nuclei. The organism will then divide into separate organisms for each nuclei that has been created.

Budding: Budding occurs when a new organism grows from the body of the parent organism. The new organism may separate from the parent or remain attached, forming colonies.

Sexual Reproduction

Sexual reproduction in protists requires two parent organisms. Both organisms contribute genetic material to the offspring. The benefit of sexual reproduction is that it creates this genetic variability. Sexual reproduction techniques that occur in protists are conjugation and alternation of generations. Conjugation occurs when two protists of the same species come together and form a temporary union. They exchange genetic material during this union. When the two protists separate, they are genetically different from the original organisms.

Week 7 is really really fun. Our class have prepared some games yeahh. But, as for me some group are lacking in their time management and also some games are quite boring. My group also lack in some aspects but it teach us to do better the next time. And after the overall results, our group have done quite a good job. Just want to share a microbiology jokes :) okay , have a good day everyone

# data[].attributes.body
This week is kinda stressful because of the tests. And on Friday we had Microbiology test. I have prepared my best but I think it still not enough. The test quite confusing but I have done my best to answer it . I will work twice or trice for the next test and make sure that I will score for the next test.

Last week, we had a lot of fun because of the mind map game . it was so big so many informations that i can see. i found that the game have its  own advantage because it show us the whole connections that i cannot see because i just read the note and understand and memorised it without relate it with each other. The link below is example of prokaryote's mind map that i can found while find some reference

Last week, he had the revision for microscopy. Dr Wan helps me to understand better in this subject . We also have divided ourselves into groups for the virtual microbe project. As for our team , we just had create our whatsapp group . Everybody seem so nice and friendly. We shared about microbe that we want to adopt. Below is the video link which show you how to oil immersion in a correct way.

and this is my evidence for the virtual lab

During wednesday class, we have doing our presentation about compound microscope  . Every group have done their bests including our groups. But we apologise  because we do not have slides to show. We just talk and talk so that why the listeners cannot focus. Everything happen for a reason . For our group , this situation had made us learnt our lesson and because of this our bond between groupmates is closer and now we know how to work with each other .
