Systems in Living Things-Heredity

7. Recognize that every organism requires a set of instructions that specifies its traits. These instructions are stored in the organism’s chromosomes.Heredity is the passage of these instructions from one generation to another.

8 . Recognize that hereditary information is contained in genes located in the chromosomes of each cell. A human cell contains about 30,000 different genes on 23 different chromosomes.

9 . Compare sexual reproduction (offspring inherit half of their genes from each parent) with asexual reproduction (offspring is an identical copy of the parent’s cell).


7. Bioengineering Technologies

Central Concept: Bioengineering technologies explore the production of mechanical devices, products, biological substances, and organisms to improve health and/or contribute improvements to our daily lives.

7.1 Explain examples of adaptive or assistive devices, e.g., prosthetic devices, wheelchairs, eyeglasses, grab bars, hearing aids, lifts, braces.


7.2 Describe and explain adaptive and assistive bioengineered products, e.g., food, bio-fuels, irradiation, integrated pest management.

Appendix III-Massachusetts Frameworks-

Historical and Social Context for Science and Technology/Engineering:
Topics for Study

III. Benefits of science and technology/engineering


• Continuous progress in personal and public health, resulting in increasing longevity
• Key discoveries and inventions and their beneficial uses (e.g., radium and the X-ray)

IV. Unintended negative effects from uses of science and technology/engineering


• How government, industry, and/or individuals may be responsible for negative effects (discuss examples here in Massachusetts, the United States, and abroad)
• Unanticipated ethical dilemmas (e.g., genetic cloning, contraceptives)

V. How science and technology address negative effects from uses of science and technology/engineering


• Examples of products and systems that address negative effects (e.g., automobile emission control devices, ceramics in car glass, biodegradable plastic)
• Costs and benefits of government regulations
• How to balance risk-taking and creative entrepreneurial or academic activity with social, personal, and ethical concerns
