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.

By PROFESSOR & PROFESSIONAL COACH

Hello,

First and foremost, I would like to wish you a warm welcome back to school and a peaceful year ahead as you work towards your goals. I am aware that the economic situation can sometimes be challenging, which is why I offer my services to accompany your child throughout their academic journey with ease and serenity.

Throughout my career as a Graduate Teacher and Graduate Professional Coach, I have worked in various contexts. Until last year, I taught in front of whole classes as well as in private lessons. Since this year, I have been providing face-to-face private lessons at home and also via video conferencing, a mode of teaching that I have practiced with university students for the past ten years.

My teaching environment has undergone significant changes, especially with the emergence of the Covid pandemic. This shift has led our secondary school students to adapt to the new mode of learning and communication, namely video conferencing. Despite the success of this transition, it is important to acknowledge that our younger students still require attention and a psycho-emotional connection in order to develop their autonomy peacefully.

Over the past two decades, I have implemented proven methodological approaches, some of which are borrowed from theater techniques, such as the Davis method (mind mappings/colors), and my specialty, professional coaching, which aims to enhance your child's motivation. My main goal is to foster agility in your child across all subjects, not only for the present but also for their future when I will no longer be by their side.

Ultimately, my objective goes beyond simply focusing on gaining points in a subject. I firmly believe in this approach due to my experience as a Mental Coach working with young athletes between Nice and Cannes, as well as throughout Europe via video conferencing, as part of their preparation for the French Tennis Championships. It has reinforced my conviction that working on a subject should be a nurtured objective that encompasses personal growth and development.

As a Professor in General Education, specializing mainly in scientific subjects, I suggest supporting your child in gaining agility in constructing their academic path during this unique period that is filled with both opportunities and challenges.

Looking forward to meeting you soon,
Corinne.

Franco-British associate professor, author at CNED, 33 years of experience from middle school to scientific preparatory classes, supports you in the success of your project in English.

Refresher training, consolidation and in-depth study, training for exams, certifications and competitions or personal projects.

Here is a non-exhaustive sample of the services that I offer:
- skills assessments,
- training for the baccalaureate exam, BTS exams
- practice exams and oral exams for CPGE (Mines Ponts - Mines Télécom - CCINP - etc.),
- training for certifications (Cambridge, TOEFL, TOEIC, IELTS, etc.),
- review and re-explanation of lessons,
- themed conversation, coaching on professional situations...

Prior to the service, we will be able to...
- define needs and potential problems
- carry out a skills assessment based on the CEFR
- co-develop a remediation or progress procedure,
- take into account the learner's courses/documents/learning materials,
- check understanding of the frameworks and expectations of programs, exams, or competitions, etc.

The session is intended to be a linguistic and cultural immersion in English, based on a communication approach.

The approach is multimodal, based on authentic and current resources and uses all language activities to progress (oral and written expression, oral and written comprehension and mediation).

During the sessions, if necessary, learning resources will be provided to expand the vocabulary, recall certain language fundamentals or remind people of a point of methodology.

For certain services (such as oral exams), working documents may be provided in advance.

This is the ultimate executive function and study skills coaching program that utilizes Artificial Intelligence as a personalized assistant.

Designed specifically for students with Special Educational Needs (SEN), including those with challenges in organization, focus, and information processing. This course provides real, measurable tools for academic autonomy.

We move beyond basic homework help. We treat the AI as a co-teacher to manage specific learning barriers:

The AI study buddy: Students learn to use generative AI (e.g., ChatGPT) ethically as a powerful organizational assistant. They master using it to summarize dense notes, break down complex science paragraphs into simplified concepts, or structure large projects into manageable steps.

Executive function tool integration: We focus on integrating AI-enabled planning apps and task management systems to assist with time management, scheduling, and project sequencing—skills essential for students with ADHD or organizational difficulties.

Personalized remediation: We leverage generative AI's power to create instant, personalized learning aids—for example, quickly generating visual study guides, mind maps, or specific practice quizzes tailored to the student's current school curriculum and unique learning style.

The Goal: To build confidence, independence, and accountability, allowing the student to navigate their schoolwork more effectively and rely less on parental or teaching support.

Why this program is premium: your investment covers the specialized pedagogical planning required for this complex integration:

It requires extensive preparation to tailor AI prompts and tools to the student's specific SEN profile (e.g., Dyslexia, Dyscalculia, ADHD).

It includes the creation of detailed progress reports and recommended toolkits for parents, ensuring strategies are consistent at home and school.
