What are microbes?
Microbes are microscopic organisms that cannot be seen with the naked eye; some are beneficial and some are harmful.
- They are found in the air, water, soil, and on the bodies of living organisms.

🔬 Types of microbes
Viruses: The smallest living organisms, they cause diseases such as influenza and AIDS.
- Bacteria: Some are beneficial (such as yogurt bacteria), and some are harmful (such as typhoid bacteria).
- Fungi: such as yeast used in bread making, including harmful ones like a fungus that causes skin diseases.
- Protozoa: such as amoebas that cause dysentery.

🌍 Where it is found
- In the soil, water, and air.
- Inside the bodies of living organisms and on their surface.

✅ Benefits of microbes
- Production of some medicines, such as penicillin, from fungi.
- Manufacturing foods such as yogurt and cheese using beneficial bacteria.
- Analysis of organic matter and restoration of elements to the soil.

⚠️ The dangers of microbes
- It causes serious diseases such as: typhoid, dysentery, influenza.
Food spoils when it grows on it.

🛡️ Ways to prevent microbes
- Wash your hands thoroughly before and after eating.

How the body's systems work to meet the needs of living organisms - Fourth Grade - First Semester

28.85 € /h

How do the body's systems work together?
- The digestive system: It digests food and converts it into simple nutrients (glucose, amino acids, fatty acids) that reach the blood to nourish the cells.
- The respiratory system: Oxygen enters the body and carbon dioxide exits, ensuring the continuation of cellular respiration within the cells.
- The circulatory system (heart and blood vessels): It transports food and oxygen to all parts of the body, and removes waste products such as carbon dioxide and urea.
- The excretory system (kidneys and skin): gets rid of waste products resulting from vital processes such as urine and sweat, in order to maintain the body's internal balance.
- The nervous system: It regulates the functioning of different organs and sends signals to control movement and respond to external stimuli.
- Muscular and skeletal system: Provides movement and support for the body, and helps protect internal organs.
- The immune system: It defends the body against microbes and foreign substances, thus maintaining health.
Summary
Each system has a specific function, but the integration of these systems is what ensures human survival. Digestion provides food, respiration provides oxygen, blood circulation delivers both to the cells, excretion removes waste, and the nervous system coordinates all of this.

Mitosis and Meiosis - Third Preparatory Grade - First Semester

43.27 € /h

First: Mitosis

✳️ Definition:
It is a cell division that occurs in somatic cells (such as skin and muscle cells), and its purpose is growth and replacement of damaged cells.

🔁 Result:
This results in two perfectly identical cells, each with the same number of chromosomes (46 in humans).

📘 Its importance:
Growth
- Tissue regeneration
Wound healing

🧠 Stages of mitosis:
1. Prophase: Chromosomes begin to appear
2. Metaphase: The chromosomes are aligned in the middle of the cell.
3. Anaphase: The chromosomes separate and move to the ends.
4. Final: Two new nuclei are formed

---

🧪 Second: Meiosis

✳️ Definition:
It is a division that occurs in reproductive cells (eggs and sperm), and its purpose is to reduce the number of chromosomes by half in preparation for reproduction.

🔁 Result:
This results in four asymmetrical cells, each containing half the number of chromosomes (23 in humans).

📘 Its importance:
- Production of reproductive cells
Maintaining a constant number of chromosomes in living organisms
- Increase genetic diversity among individuals

🧠 Stages of meiosis:
It consists of two successive divisions:
First division: Reduction in the number of chromosomes
- Second division: Similar to mitosis, to form 4 cells

I am a qualified and experienced mathematics tutor. Graduated from the Free University of Brussels in 2011, I started my career by teaching remedial courses in different schools in Brussels. I then specialized in individual academic support by following educational training at the Harvard Graduate School of Education. I have been giving private mathematics lessons daily for over ten years.

The students who follow my private lessons benefit from personalized support. The first session is devoted to an in-depth assessment of the student's mathematical knowledge. The objective is to detect its weak points and understand their origin in order to adapt my courses to its needs. I develop a tailor-made remediation program for each of my students aimed at filling each of their gaps. Over the course of the sessions, the student builds a solid foundation for learning and regains self-confidence. At the same time, I help him acquire a work methodology that allows him to gradually become autonomous in his studies.

I have a thorough knowledge of the mathematics curriculum for middle and high school (from 6th to 12th grade). I am also qualified to support students in preparing for international exams such as the SAT, the OMPT, and the International Baccalaureate (IB) in all its variations: Analysis and Approaches (AA SL/HL) and Applications and Interpretation (AI SL/HL).

Throughout my years of training, I studied and developed numerous techniques that facilitate learning mathematics. The strength of my teaching approach lies in my ability to explain, in simple terms, anything a student finds complicated. I am passionate about this profession because it offers me the opportunity to guide struggling students toward success. It is a true pleasure to see them progress and rediscover their connection with the fascinating world of mathematics.

I offer private tutoring in Paris (at the student's home) or remotely (online). My online lessons take place on an interactive whiteboard. This whiteboard is specifically designed to facilitate student/teacher interaction online. Thanks to this teaching tool, my online lessons are just as effective as in-person lessons. The student only needs an internet connection and a computer, tablet, or smartphone to participate.

Physics and chemistry are the gateway to understanding all sciences, as a science student you will need to be able to sort through the many complex features to become a true student scientist with a critical and curious mind. That's why I designed this course to help students prepare for their exams and the next school year to fill in the gaps they have in math and science.
I would like to inform you that I am a young researcher and I can also help you to acquire basic knowledge of Microsoft Office and other essential software for your career.

Dutch can sometimes be difficult: grammar, spelling, reading comprehension, summarizing, or writing good texts. In these tutoring sessions, I help students step by step to become stronger and more confident in the subject of Dutch.

The lessons are practical, clear, and tailored to the student's level and goals. Together, we work on grammar, vocabulary, spelling, writing skills, speaking skills, and reading comprehension. In addition, I pay attention to study skills, so that students not only achieve better grades but also learn to work more independently.

I use many examples, exercises, and active assignments to make the material understandable and applicable. Whether it concerns VMBO, HAVO, VWO, NT2, or general language proficiency: the lessons are tailored to what the student needs.

My goal is not only to understand Dutch better, but also to develop more enjoyment and confidence in language.

I offer structured, one-on-one tutoring in physics and mathematics for secondary and university students. Sessions are in English or Spanish, depending on your preference.

What I cover:

-Physics — IB SL/HL, A-Level, IGCSE, Belgian/French secondary, first and second-year university (mechanics, electromagnetism, thermodynamics, waves, modern physics)
-Mathematics — IB SL/HL (Analysis & Approaches), A-Level, IGCSE, calculus, linear algebra, STEM entrance preparation

How sessions work:

-The first session is diagnostic — we identify the actual gaps, set a plan, and decide whether we're a good fit. After that, sessions combine conceptual work, problem-solving, and past-paper practice depending on what's coming up.
I give specific, honest feedback after each session. For younger students, I'm happy to share a short written summary with parents.

Format: Online via video, or at the student's home within Brussels Region.
