    Biology.pdf
    Can you explain the difference between mitosis and meiosis?
    R
    Great question!• Mitosis = copying. 1 cell → 2 identical cells. Growth & repair.• Meiosis = creating diversity. 1 cell → 4 unique cells. For reproduction only.
    Why does meiosis produce 4 cells?
    R
    It divides twice (Meiosis I and II) — first separating homologous chromosomes, then sister chromatids. Result: 4 haploid cells. 🔬

    See why 1.3M+ students in 170+ countries switched to Raena AI.

    Honestly, Raena AI has saved my life. I am studying fast track paramedicine and am also working full time and before I discovered Raena I was falling behind in my studies and couldn't keep up. Now I am excelling in all my subjects because I actually have time to study all thanks to this amazing platform.

    It helped summarize large notes to better understand by highlighting the main points. It helped answer questions that I couldn't handle and explained things that I couldn't understand. It has helped me a lot.

    I use Raena AI for every single test. As a student nurse taking anatomy and microbiology classes, Raena AI is a part of my study routine in every course I take. I went from getting 50s in my tests to 90s with the implementation of this tool. I have also shared this website with many friends and colleagues wishing to help them out, which they too have had positive experiences, and you can see in the picture I promoted this website multiple times.

    I have been diagnosed in the past year with Macular Dystrophy, an eye condition in which I have loss of vision in my central vision. This makes is significantly harder and takes a lot longer to read documents, and see detailed. So, I signed up to Raena AI in an attempt to help summarise my Uni readings and documents, to help me read faster, and keep up with the content and my peers. I have been using it for a while now, it it has honestly saved my life! I no longer feel 'left behind' because it takes me longer to read, and i can't skim and scan. Now, I feel like I can keep up with my work, and finish my degree with good marks again! Thank you so much for helping me, I don't know what I would have done without it!

    I'm writing this as the dentistry faculty top student of the first semester, with 3.93 GPA, thanks to Raena AI. I've discovered Raena AI at the second midterms and it literally changed my academic life. I use the summary option religiously. It simplifies the most complex lectures into something still detailed but much more understandble. I genuinly thank you for your services, my academic game can not be matched now. With gratefulness, Asel.

    Raena has allowed me to understand and simplify complex topics within accounting and finance. From this, I can implement small changes to my answer and overtime, this allowed me to make more comprehensive answers and in thus, allow me to get better grades.

    As a college student, lecturers usually give 60+ PowerPoint slides per lecture. I would spend days going through each single slide and trying to get the right information from it, sometimes even getting the useless information. With Raena AI, it gives me the summary in seconds, plus I can get podcasts or flashcards to help me study much better. Using this tool, I am not behind anymore on any of my content and I can get more done than ever. Raena AI saves time and lives.

    Raena helps me make summaries of very long chapters into smaller and easy-to-read paragraphs. It has impacted my learning as my study time is less but more efficient. I also use it to create quizzes about topics I need to know and this makes it fun to learn and test myself.

    I typically use Raena AI for everything school-related, it's insane how such a platform could help a number of people. I use it especially for studying for my finals, every semester, as the work load in campus can be a little too overwhelming. I like summarizing my school PDF's beforehand to avoid burn out and I especially love how quirky the brain rot videos are because they help me understand better when I'm unmotivated. This website is too good, i had to put my girl friend on.
