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.

Graduated and experienced for more than 18 years, I give private lessons in Mathematics - Analysis - Matrices - Statistics - Algebra - Geometry - Physics - Chemistry - Biology, Geology to students of French program of Terminales, patent and secondary or international programs (IB ) or Canadian in English (Grade 8, 9, 10, 11, 12) or competitions and medical university preparatory classes or 1st and 2nd university years for the academic year 2022/2023 either at home or by internet online by virtual class method .
The online method is easily done by a link that serves as a writing board, typing and projection more than Skype or Zoom talking about which we communicate. This method is very modernized and reliable (it's like we are in the same place) for more than 6 years I have been working by this method.
The results of my students and in particular the students of Terminale are superb with successes in mention very good and good and sometimes excellent.
Homework help for CNED students.

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 !

Welcome to university students or masters and doctoral students!!! I teach the course of Natural Products Chemistry or Phytochemistry or Pharmacognosy. In this class we will learn about the methods of extracting, separating and identifying the chemical form of active chemical compounds (biologically active secondary compounds) from natural sources, such as medicinal and aromatic plants. We will also discuss what is known as chromatography, spectroscopy, spectroscopy, mass spectrometry, magnetic resonance and advanced analysis devices used in this field.

This is in addition to knowing some important applications of these active materials in various fields, such as the pharmaceutical industry, agriculture, etc. We will also learn the practical and laboratory methods that are carried out in the laboratory to conduct toxicity, antioxidant, and diabetes analyses, etc.

Experience: About 20 years of practical experience in the field of chemistry, medicinal and aromatic plants and pharmacy with parallel training and private lessons for science and chemistry curricula.

With my qualifications and experience, I hold a master’s degree and a doctorate in organic chemistry (chemistry of natural products), in addition to other graduate degrees and a doctoral scholarship in pharmaceutical sciences in Belgium from the Erasmus Mendus Organization of the European Union.

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.
