Lesson Note on the Human Kidney Topic: The Human Kidney Duration: 40 minutes Specific Objectives: By the end of the lesson, students should be able to: Define the kidney and state its location in the human body. Identify and describe the structure and functions of the kidney. Explain the processes involved in urine formation (filtration, reabsorption, and secretion). Describe how the kidney contributes to homeostasis. Identify common kidney-related diseases and how to prevent them. Evaluate the importance of maintaining kidney health. Lesson Content: 1. Introduction to the Human Kidney The kidneys are vital organs in the human body responsible for filtering waste from the blood and regulating water and electrolyte balance. They are part of the excretory system and play a crucial role in homeostasis. Location: The kidneys are located in the abdominal cavity, on either side of the spine, just below the rib cage.

LESSON NOTE ON BIOLOGY OF HEREDITY

TOPIC: BIOLOGY OF HEREDITY   DEFINITION OF HEREDITY  Heredity is the passing down of traits from one generation to the other. It is the reason why children have similar physical and behavioral traits as their parents and grandparents. It is crucial in the study of genetics, biology, and evolution. TRANSMISSION AND EXPRESSION OF CHARACTER IN ORGANISM The transmission and expression of characters in an organism takes place through the genetic material, which is the DNA. DNA contains genes that code for specific traits such as eye color, height, and hair texture. The genes are located on the chromosomes, which are thread-like structures found in the nucleus of a cell. The expression of these genes occurs through the process of transcription and translation, where the genes are turned into proteins. DEFINITION OF GENETIC VARIATION  Genetic variation refers to the differences that occur between individuals of the same species. It is brought about by mutations that alter the DN...
