Introduction: The regulation of body temperature is called thermo-regulation. It is the ability of any organism to maintain the temperature of its body at normal level even when the temperature of the external environment is fluctuating. The normal temperature of the body of humans is approximately 37◦C or between the 98◦F-100◦F and it is called its core body temperature. This core temperature usually remains the same within a very short range of variations. This core temperature only

Chapter 7: Neurulation and the Formation of Axial Structures Neurulation The stage of organogenesis in vertebrate embryos‚ during which the neural tube is transformed into the primitive structures that will later develop into the central nervous system. In development‚ this starts with the first traces of formation of the neural plate and ends with closure of the neural tube. Induction Process by which the presence of one tissue influences the development of another. Some considerations:

Introduction Staphylococcus aureus (S. aureus) was first discovered in the 1880s and is a dangerous and versatile pathogen that causes many types of severe diseases. Most commonly it causes skin infections‚ respiratory tract infections‚ and food poisoning. In the 1940s‚ when the antibiotic medications such as penicillin was discovered and introduced‚ it became a primary treatment for S. aureus infections. However‚ misusing and overusing the use of antibiotics caused the evolution of these bacteria
