Exceptions are runtime errors or unexpected events that disrupt the normal flow of a program. They can occur due to various reasons, such as invalid user input, file not found, or division by zero. Exception handling is a mechanism used to manage these errors gracefully, ensuring the program doesn't crash and can recover or provide meaningful feedback. This is achieved using constructs like try, catch (or except), and finally. The try block contains code that might throw an exception, the catch block handles the exception, and the finally block executes cleanup code regardless of the outcome. Effective exception handling improves a program's robustness and user experience.

Object-Oriented Programming (OOP) is a programming paradigm based on the concept of "objects," which represent real-world entities or abstractions. Objects encapsulate data, called attributes, and behavior, called methods, into a single unit, promoting modularity and reusability. OOP relies on four key principles: encapsulation, which restricts direct access to an object's data; inheritance, allowing new classes to inherit properties and behavior from existing ones; polymorphism, enabling methods to perform differently based on the context or object; and abstraction, which hides complex implementation details to provide a simplified interface. These principles make OOP effective for building scalable, maintainable, and efficient software systems.

Protection: Amniotic fluid acts as a shock absorber hence protecting the fetus from any external trauma or sudden movement during pregnancy 2. Regulation of temperature : The Amniotic fluid is warm and of constant temperature hence it prevents fluctuation of temperature in the womb and keeps the fetus warm . 3. Provides lubrication: When body parts like the toes and fingers fuse together friction may occur leading to some damage hence the amniotic fluid provide lubrication preventing fusing.

Gastrulation is the process of formation of trilaminar disk (gastrular) .The cells from the epiblast migrate and differentiate to form the 3 layers i. Ectoderm ii. Mesoderm iii. Endoderm

Every year about 9 million children in developing countries die before they reach their fifth birthday, many of them during the first year of life. Ethiopia has one of the highest under-five mortality rates with more than 321,000 children under the age of five dying every year.

The placenta is a temporary organ of pregnancy found in the uterus; formed from fetomaternal components facilitating the exchange of substances between the mother and the growing fetus. The placenta is a vital organ with multiple functions, such as endocrine, immune, and physiological.

At puberty, hypothalamus is stimulated to produce GnRH to the adeno-hypo-physeal • Production of either follicle stimulating hormone(FSH) or Luteinizing hormone (LH) to the female ovary or male testes. • In males the FSH effects spermatogenesis in the seminiferous tubules within the testis • In females stimulates the maturation of graafian follicle in ovary • FSH stimulates secretion of estrogen in female, androgens in males and LH stimulates secretion of progesterone

Refers to nursing care organizational modalities Nursing modalities are dependent on organizational philosophy, nursing staff, client population and patient condition.

This course provides an introduction to programming techniques to understand the concepts and principles of procedural programming language, formulate basic problem solving techniques, analyze problems and implement basic algorithms for their solution. The unit also aims to show ability in testing and debugging of programs.

Is the process of identifying an existing problem. Determining the root cause or causes of the problem/deciding the best course of the action in order to solve the problem and then finally implementing it to solve it. Simply methodology for solving everyday issues
