Sample questions: What strategies are included in public health initiatives aimed at reducing the incidence of smoking-related diseases? What impact have these initiatives had on smoking rates and associated medical costs? How have health authorities responded to the threat of West Nile virus? What effect does this response have on people’s lifestyles? How did various cultures attempt to prevent disease be- fore vaccines were available? What impact have vaccines had on global health?
By the end of this course, students will:
B2.1 use appropriate terminology related to cells, tissues, organs, and systems of living things, in- cluding, but not limited to: absorption, anaphase, capillaries, concentration, differentiation, diffusion, meristematic, mesophyll, phloem, prophase, red blood cells, regeneration, stomate, and xylem [C]
B2.2 examine cells under a microscope or similar instrument to identify the various stages of mi- tosis in plants and animals [PR, AI]
B2.3 examine different plant and animal cells (e.g., cheek cells, onion cells) under a microscope or similar instrument, and draw labelled biologic- al diagrams to show how the cells’ organelles differ [PR, C]
B2.4 investigate, using a microscope or similar in- strument, specialized cells in the human body or in plants, focusing on different types of cells (e.g., bone, muscle, leaf, root cells), and draw labelled biological diagrams to show the cells’ structural differences [PR, C]
B2.5 investigate the rate of cell division in cancer- ous and non-cancerous cells, using pictures, videos, or images, and predict the impact of this rate of cell division on an organism [PR, AI]
B2.6 investigate, through a laboratory or computer- simulated dissection of a plant, worm, fish,
or frog, the interrelationships between organ
systems of a plant or an animal (e.g., between the root system and leaf system in a plant; between the digestive system and circulatory system in an animal) [PR, AI]
B2.7 use a research process to investigate a disease or abnormality related to tissues, organs, or sys- tems of humans or plants (e.g., heart disease, tobacco mosaic virus, wheat rust) [IP, PR, C]
B. Understanding Basic Concepts
By the end of this course, students will:
B3.1 describe the cell cycle in plants and animals, and explain the importance of mitosis for the growth of cells and repair of tissues
B3.2 explain the importance of cell division and cell specialization in generating new tissues and organs (e.g., the division of stem cells into specialized cells such as muscle cells or nerve cells in humans; the division of meristematic cells to expand and differentiate plant tissue)
B3.3 explain the links between specialized cells, tis- sues, organs, and systems in plants and animals (e.g., muscle cells and nerve cells form the tissue found in the heart, which is a component of the circulatory system; granum and thylakoid struc- tures act as solar collectors in the chloroplast to produce carbohydrates for plant growth)
B3.4 explain the primary functions of a variety of systems in animals (e.g., the circulatory system transports materials through the organism; the respiratory system supplies oxygen to and re- moves carbon dioxide from the body)
B3.5 explain the interaction of different systems within an organism (e.g., the respiratory system brings oxygen into the body, and the circulatory system transports the oxygen to cells) and why such interactions are necessary for the organ- ism’s survival
