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.

The math, physics, chemistry, and SVT courses of the French or Swiss program of maturity or university are done by either in-depth explanations or by a quick course and summary of essential needs according to the case of each student supported by exercises from the book or evaluations and exams from other high schools.
A special follow-up program to better prepare for the Terminales session.
So that I can give support courses for the 1st year of university in Mathematics - Analysis - Matrices - Statistics - Algebra - Geometry - Physics - Mechanics - Electricity - Chemistry - Organic Chemistry - Biology, Geology.
My experience is too long and for years I have learned methods for each case and for each student to fill in their gaps with the best results of Excellent, Very Good, and Good as mentioned by my students.
I can also help students to better prepare for courses and support them to better prepare for the duties of CNED in science subjects.
Guaranteed response within minutes up to 10 hours maximum.

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.

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 !

I'd like to start by greeting everyone who is reading this and then briefly discuss the teachings I'm providing. Going to medical school is a major step, and while becoming a doctor may have been a big dream of yours, things unfortunately didn't turn out the way you had hoped. You didn't receive what you eagerly want following your bac. I'm here to tell you that earning your bac is just the first step on a longer journey. You have another opportunity to fulfill your lifelong ambitions. What role do I play in this? as someone who has been in your position and ultimately obtained what I want. We will have a customized plan that fulfills your needs, we will correct any unsuccessful methods and build new ones, and I will lead you through the program at every stage.

Chemistry and Biology that understand, connect, and apply each other

My high school Chemistry and Biology classes are designed to help students understand science clearly, dynamically, and meaningfully, integrating key concepts with real-world applications. I guide my students in developing a deep understanding that goes beyond memorization, fostering analysis, scientific reasoning, and critical thinking.

With a solid background in Food Biotechnology and extensive teaching experience, I integrate modern methodologies such as problem-based learning, case studies, digital simulations, and interactive activities that connect chemistry and biology with topics such as health, nutrition, genetics, biotechnology, sustainability, and the environment.

The classes are personalized and adapted to each student's pace, reinforcing content, preparing for assessments, and developing key scientific skills: data interpretation, understanding processes, scientific argumentation, and problem-solving. My approach aims to help students gain confidence, academic independence, and a passion for science.

These classes are ideal for students who:

They want to understand Chemistry and Biology without frustration

They seek to improve their academic performance

They need personalized support

They want a science that is current, applied, and connected to real life.

Science with meaning, learning with purpose, and support that makes a difference.
