Constant speed and variable speed - Second year of secondary school

Translated by GoogleSee original

From 58.8 € /h

First: Regular speed
It is the speed that does not change with time, meaning the body moves at the same rate all the time.

✳️ Its characteristics:
- The distance traveled is constant in each unit of time.
- The graph between distance and time is a slanted straight line.
Example: A car traveling at a speed of 60 km/h without changing.
Second: Variable speed
It is the speed that changes with time, meaning the body can speed up or slow down while moving.

✳️ Types:
- Positive acceleration: when speed increases with time.
Negative acceleration (deceleration): when the speed decreases over time.

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

29.4 € /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.

- 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

My name is Fawzi, and I am a French language teacher. Since 2012, I have been giving private lessons online. My objective is to support learners towards success in the DELF (Diploma of Studies in French Language) or the DALF (Advanced Diploma in French Language), as well as the TCF (French Knowledge Test). I have had the pleasure of helping many students of different nationalities through my online courses. For me, helping enthusiasts practice the French language is an enriching experience, because I understand the importance of success in the lives of ambitious people.

I speak Arabic, French, Spanish, a little English and a little Turkish. During my classes, I explain concepts in French, Arabic or Spanish, depending on your preference. At the end of each session, I offer exercises to do as homework, in order to identify your gaps and monitor your progress.

Here are some essential points to know about the DELF and DALF:
- The DELF (Diploma in French Language Studies) and the DALF (Advanced Diploma in French Language) are two high-quality official diplomas. They are aligned with the levels of the Common European Framework of Reference for Languages and cover the following six levels, from the most basic to the most advanced: A1, A2, B1, B2, C1, C2. These diplomas are suitable for all ages and all audiences.
- The DELF B2 and, increasingly, the DALF C1, provide access to French, European or French-speaking universities, as well as certain Grandes Ecoles.

If you plan to take DELF or DALF exams, or if you want to improve your level, do not hesitate to book your sessions with me to start preparation. I am available !
