Homeostasis is one of the topics one should be expecting in examinations like IGCSE, GCSE, WASSCE, GCE, NECO, SAT.

Osmoregulation (homeostasis)-in unicellular organism is ensured by the use of contractile vacuole. The main organs involved in homeostasis in multicellular organisms include kidney, liver, skin, ductless glands (hormones) and the brain which has the overall control of the homeostatic process in the body.
The regulation of homeostasis depends on three mechanisms:
1. Receptor 2. Control Centre 3. Effector.
The entire process continuously works to maintain homeostasis regulation.
1. Receptor: the receptor is the sensing component responsible for monitoring and responding to changes in the external or internal environment.
2. Control Centre: The control centre is also known as the integration centre. It receives and processes information from the receptor.
3. Effector: The effector responds to the commands of the control centre. It could either oppose or enhance the stimulus.

Biological systems like those of your body are constantly being pushed away from their balance points. For instance, when you exercise, your muscles increase heat production, nudging your body temperature upward. Similarly, when you drink a glass of fruit juice, your blood glucose goes up. Homeostasis depends on the ability of your body to detect and oppose these changes.
Roles of Pancreas and Liver in Homeostasis.
During a meal, the pancreas will secrete insulin and suppress glucagon, causing the liver to store glucose as glycogen.
Alternatively, when blood sugars are low, the liver can convert glycogen into glucose through a process known as glycogenolysis.
The pancreas controls the concentration of glucose in the body by producing the hormones insulin and glucagon which stimulate the liver. Insulin and glucagon are chemical hormones messengers.

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 !

Struggling with math, physics, or chemistry? You're not alone — these subjects are hard, and classroom explanations are rarely enough.
I offer personalized tutoring for middle school, high school, and early university students following the French Mission curriculum, the Moroccan national curriculum, or the international baccalaureate.
Topics covered:

Mathematics: algebra, geometry, calculus, trigonometry, probability
Physics: mechanics, electricity, optics, thermodynamics
Chemistry: organic, inorganic, stoichiometry, reactions

My approach:
I don't re-explain the textbook — I identify exactly where your understanding breaks down and fix it from there. Each session is built around your specific difficulties, not a preset program.
I completed CPGE (Classes Préparatoires aux Grandes Écoles) in Mathematics and Physics before graduating as a State Engineer — I know these subjects at an advanced level and I know where students typically get lost.
Individual and small group sessions available. Online (worldwide) in French, Arabic, or English.

As a child i struggled with particular subjects and found learning to be demoralising.
In middle school, I was fortunate enough to have teachers who through positive encouragement and persistence made those subjects my favourite even to this date.
I aspire to become like them for someone else.I try to make learning fun,eventful and creative which is curated according to the students needs, capacity and circumstances.
As a working candidate,I had the opportunity to tutor students in all subject areas during my post graduation.I have 7+ years of teaching experience.
So rest assured,you will be safe hands.
