Structure
and Function – How are organisms structured to ensure efficiency and
survival? 7.2
Many organisms, including humans, have specialized organ systems that
interact with each other to maintain dynamic internal balance. ¬
All organisms are made
up of one or more cells; each functions more or less independently. ¬
Multicellular
organisms need specialized structures and systems to perform basic life functions.
|
C15. Describe the basic structures of an animal cell, including nucleus,
cytoplasm, mitochondria and cell membrane, and how they function to support
life. C 16. Describe the structures of the human digestive,
respiratory, and circulatory systems, and explain how they function to bring
oxygen and nutrients to the cells and expel waste materials. C 17. Explain how the human muscular/skeletal system
supports the body and allows movement. |
|
Heredity
and Evolution – What are the processes responsible for lifeÕs unity and
diversity? 8.2
Reproduction is a characteristic of living systems and it is essential for
the continuation of every species. ¬
Heredity is the
passage of instructions specifying traits from one generation to another. ¬
Some of the characteristics
of an organism are inherited and some result from interactions with the
environment. |
C 25. Explain the similarities and differences in cell
division in somatic and germ cells. C 26. Describe the structure and function of the male and
female human reproduction system, including the process of egg and sperm
production. C 27. Describe the structure of the genes on chromosomes,
and explain sex determination in humans. |
|
Science
and Technology in Society – How do science and technology affect the
quality of our lives? 7.4 Technology
allows us to improve food production and preservation, thus improving our
ability to meet the nutritional needs of growing populations. ¬ Methods have been developed to prevent food spoilage
caused by bacteria. |
C 21. Describe
how freezing, dehydration, pickling and irradiation prevent food spoilage
caused by bacteria. |
