Based on experiences at home or in the classroom for example, students should be able to discuss how to grow something or to keep something alive. Explain biological diversity in terms of the transmission of genetic characteristics. Students should be familiar with concepts related to population biology, including adaptation and offspring variability, and how different modes of reproduction affect genetic variability within a population or generation. Beyond the contrast of differences, many strategies for passing along genetic traits can be found among living things. Similarities and differences within and between species can be explored, using simulations and models.
Concepts covered include Mendelian genetics and natural selection.
Describe how organisms accomplish basic life functions at various levels of organization and structure. Describe a life function like digestion complete with the appropriate anatomy Students should be familiar with how plants and animals accomplish basic life functions, such as respiration, reproduction, growth and development, energy use, circulation, digestion, excretion, and photosynthesis at various levels of organization. The association or lack of association between anatomy and life activity is included in this concept. Students should be investigating the principles that describe and predict behavior and functions of organisms, using models and analogies to draw comparisons and illustrate similarities. Describe the ways scientific ideas have changed using historical contexts.
