oh hi readers! so there's a reason why I made this blog. My biology teacher gave us a presentation about Protista and after she presented that we thought that we need that presentation for studying soooo we asked our teacher to give us that presentation via email but she said that she would just send the presentation to one student which is me and I'm the one who has to spread out the presentation and uhm, I decided to just post the presentation on a blog so everyone, not just Slamet Riyadi students, can see it.... yeah that's the reason. and I hope the materials that I post give you an useful information! :-)
