...that can be absorbed through the digestive system and then transported to each cell, which was on the other hand discussed in Grade 7 to be the basic unit of life. The learners have also discovered that cells divide to produce new cells by mitosis and meiosis. They have understood that meiosis is an early step in sexual reproduction that leads to variation. Students have been introduced to genetics to be able to appreciate evolutionary differences among species. Learners have also found out that biodiversity is the collective variety of species living in an ecosystem, and by studying the ecosystem; they have come across the various cycling of materials and energy transformation. DRAFT April 29, 2014 All modules in Grade 9 Unit 1-Living Things and Their Environment present student-centered activities that will allow the learners to discover and develop concepts that they may consider useful to their everyday life. At the end of each lesson, key concepts are provided for the students to grasp ideas and information that they will remember even after they have left school. Instructional activities are designed to build up the students’ knowledge, understanding, skills, and ability to transfer learning. The modules generally use authentic assessment for the students to perform real-world tasks demonstrating meaningful application of essential knowledge and skills. There are four modules in this quarter, namely: Module 1: Respiratory and Circulatory Systems Working Together with...

...Bodily Systems and the Spatial-Functional Structure of the Human Body Barry Smith, PhD1,2, Igor Papakin1, Katherine Munn1 1Institute for Formal Ontology and Medical Information Science Faculty of Medicine, University of Leipzig, Leipzig, Germany 2Department of Philosophy, University at Buffalo, Buffalo, NY, USA Abstract. The human body as conceived by medical science is a system made of systems. The body is divided into bodily systems proper, such as the endocrine and circulatory systems. These are subdivded into many subsystems at a variety of levels whereby all systems and subsystems engage in massive causal interaction with other systems and subsystems. In this essay we offer an explicit definition of bodily system, and explicit means for understanding these causal interactions. Whereas informality is acceptable in documentation created for human beings, it falls short of what is needed for computer representations. In our analysis we will define bodily system, and will take some first steps toward understanding the causal relationships bodily systems have with their subsystems. 1. Introduction Ontology plays an increasingly significant role in work on terminology and knowledge management systems in the domain of biomedical informatics, and we hold that it will play an essential role in biomedical research of the future. The term ‘ontology’ must, however, be understood in the right way [1]. The dominant paradigm might be referred to as ‘applications...

...anatomy and physiology of human body systems. Learners will be able to gain an overview of the organisation of the human body before looking at how body systems work together to provide energy for the body. Learners will have the opportunity to investigate how homeostatic mechanisms operate in the body. Unit introduction This unit introduces core knowledge of cellular structure and function, and the organisation of the body as a whole, and then builds on this to develop a more detailed knowledge of the fine anatomy and physiology of the systems involved in energy metabolism. Learners will examine the homeostatic mechanisms involved in regulating these systems to maintain health. Learners will be given the opportunity to undertake practical activities which will require them to take measurements of the cardio-vascular system, the respiratory system and of body temperature, using noninvasive techniques to investigate normal responses to routine variations in body functioning. This unit provides the core understanding of human physiology that underpins the study of the specialist physiology units within this programme. The unit also provides an overview of body functioning that is valuable for anyone working or intending to work in a field relating to health and social care. Learning outcomes On completion of this unit a learner should: 1. Know the organisation of the human body 2. Understand the functioning of the body systems associated with energy metabolism ...

Compare compact and spongy bone. Compact bone is dense bone with very few spaces and is covered by a nourishing membrane called the periosteum. Spongy bone is identified by its many spaces that are filled with red bone marrow, which produces red blood cells. 3. Describe the structure of a long bone. Where are the yellow and red marrow found in adults? A long bone in the human body contains both compact bone and spongy bone. The compact bone is found on the outer surface of the bone and compose the shaft. The spongy bone is found at the ends of the long bone. Yellow bone marrow it found in the central shaft of the long bone surrounded by the compact bone. Red bone marrow is found in spaces of the spongy bone. 4. Describe the structure of an osteon, and explain the function of osteocytes and the central canal. The osteon consists of a central canal surrounded by concentric rings of osteocytes (mature bone cells) in a rigid matrix. O steocytes are located within a lacuna in the matrix. Canals connect the lacunae to each other and to the central canal. This allows for the transport of items between the cells and the blood vesels in the central canal. 5.

...period how long a wave lasts when it arrives at a fixed point (measured in seconds) 3. What are radio waves? An electromagnetic wave of a frequency used for long distant communication. 4. Explain the difference between a transverse wave and a longitudinal wave, and give examples of each. In a longitudinal wave, the vibration travels in the same direction that wave travels. Examples of longitudinal waves include: Sound, p-waves (earthquakes) In a transverse wave, the vibration direction is perpendicular to direction that wave travels. Examples include: Light/electromagnetic, (radio, microwave, xray, etc.), water waves, swaves (earthquakes). The major difference between longitudinal and transverse waves is their direction. Longitudinal waves move left to right while transverse waves move up and down. 5. Compare and contrast: light waves vs. sound waves Light waves are transverse and sound waves are longitudinal. Light waves can travel through a vacuum but sound waves cannot. Speed of light is nearly 300 million m/s while sound has a speed of about 340 m/s. 6. What changes the pitch of sound? The frequency of vibration. Faster vibration would cause a higher pitch while slower vibration would cause a lower pitch. 7. Explain how different factors affect the speed of sound? Speed of sound depends on factors such as altitude, humidity, and temperature because sound waves need molecules to collide in...

...they can form hydrogen bonds with each other. This are continuing breaking and reforming, so the molecules can move around. Property of water Solvent Importance Metabolic processes in all organisms rely on chemicals being able to react together in solution Examples 70-95% of cytoplasm is water. Dissolved chemicals take part in processes such as respiration and photosynthesis in living organisms Liquid The movement of materials around organisms, both in cells and on a large scale in multicellular organisms requires a liquid transport medium Water molecules stick to each other creating surface tension at the water surface. Cohesion also makes long, thin water columns very strong and difficult to break Blood in animals and the vascular tissue in plants use water as a liquid transport medium Cohesion Freezing Water freezes, forming ice on the surface. Water beneath the surface becomes insulated and less likely to freeze Thermal stability Large bodies of water have fairly constant temperatures. Evaporation of water can cool surfaces by removing heat. Metabolic Water takes part as a reactant in some chemical processes Transport of water in the xylem relies on water molecules sticking to each other as they are pulled up the xylem in the transpiration stream Some small organisms make use of surface tension to ‘walk on water’ Organisms such as...
