Skeletal System The human skeleton is divided into two main parts the axial skeleton and the appendicular skeleton. The axial skeleton consists of the vertebral column, the rib cage, and the skull. The appendicular skeleton consists of the pectoral girdles, the upper limbs, the pelvic girdle, and the lower limbs. Identify 20 major bones in the body. The following are major bones in the body: Cranium, mandible, femur, patella, scapula, ulna, clavicle, humorous, sternum, lumbar, vertebrae, cervical vertebrae, radius, pubis, carpals, metacarpals, sacrum, coccyx, tibia, phalanges, ilium, fibula, tarsals, and ribs. State the functions of the skeletal system.

Chapter Forty-Two: Circulation and Gas Exchange Preface All animals must exchange substances with the environment. Unicellular animals may directly exchange with the environment. Nutrients and oxygen enter through the plasma membrane to the cytoplasm while carbon dioxide and metabolic by-products exit from the cytoplasm through the plasma membrane. Multicellular organisms cannot exchange material at the cellular level and therefore rely on specialized systems that carry out exchange with the environment and transport the material from the sites of exchange to the rest of the body. Concept One: Circulatory systems link exchange surfaces with cells throughout the body

The Nervous System Function: The function of the nervous system is to control and coordinate functions throughout the body and respond to external and internal stimuli. The nervous system is divided into 2 parts the PNS (peripheral nervous system) and the CNS (central nervous system), and is in control of both. Nerve signals are transmitted through these systems. Interdependence: The nervous system relies on the muscular system to work properly. Organism Comparison: A flatworm?s nervous system is simpler compared to humans. It has nerve cords that control its actions. The Skeletal System

Biology B3 B3.1 Exchange of materials 1.1 Osmosis Osmosis is the net movement of water particles from an area of high water concentration to an area of low water concentration across a partially permeable membrane (e.g. a cell membrane) It?s random and re quires no energy 1.2 Active transport Cells may need to absorb substances which are in short supply, i.e. against the concentration gradient. To do this they use active transport to absorb substances across partially permeable membranes Active transport requires the use of energy released in respiration Cells are able to absorb ions from dilute solutions. For example, root cells absorb mineral ions from the dilute solutions in the soil by active transport Glucose can be reabsorbed in the kidney tubules by active transport

Performance task #3 1. Hypothesis: If you fertilize the ocean with iron then, it will help reduce atmospheric carbon dioxide levels. 2. Step-by-Step procedure: 1. Dissolve 7 metric tons of iron sulfate in acidic sea water.?? 2. Spew the solution into a ships propeller wash on a specific date covering a circular patch in the eddy. 3. Cover in iron in a circular path for 167 square km (0.01 grams per square meter. ? 4. Monitor the fate of the patch, off and on for 5 weeks while adding supplemental iron fertilizer after every 2 weeks to keep concentrations high enough to promote growth. ?? 5. Record the microscopic life bloomed on a data table.
