Structure and Function – How are organisms structured to ensure efficiency and survival?

10.1 - Fundamental life processes depend on the physical structure and the chemical activities of the cell.

¨       Most of the chemical activities of the cell are catalyzed by enzymes that function only in a narrow range of temperature and acidity conditions.

¨       The cellular processes of photosynthesis and respiration involve transformation of matter and energy.

 

 

 

D 1.           Describe significant similarities and differences in the basic structure of plant and animal cells.

D 2.           Describe the general role of DNA and RNA in protein synthesis.

D 3.           Describe the general role of enzymes in metabolic cell processes.

D 4.           Explain the role of the cell membrane in supporting cell functions.

 

Science and Technology in Society – How do science and technology affect the quality of our lives?

10.2 - Microorganisms have an essential role in life processes and cycles on Earth.

¨       Understanding the growth and spread patterns of viruses and bacteria enables the development of methods to prevent and treat infectious diseases.

 

 

D 5.           Describe the similarities and differences between bacteria and viruses.

D 6.           Describe how bacterial and viral infectious diseases are transmitted, and explain the roles of sanitation, vaccination and antibiotic medications in the prevention and treatment of infectious diseases. 

D 7.           Explain how bacteria and yeasts are used to produce foods for human consumption.

Science and Technology in Society – How do science and technology affect the quality of our lives?

10.3 - Similarities in the chemical and structural properties of DNA in all living organisms allow the transfer of genes from one organism to another.

¨       The principles of genetics and cellular chemistry can be used to produce new foods and medicines in biotechnological processes.

 

D 8.           Describe, in general terms, how the genetic information of organisms can be altered to make them produce new materials.

D 9.           Explain the risks and benefits of altering the genetic composition and cell products of existing organisms.

Heredity and Evolution – What processes are responsible for life’s unity and diversity?

10.4. - In sexually reproducing organisms, each offspring contains a mix of characteristics inherited from both parents.

¨       Genetic information is stored in genes that are located on chromosomes inside the cell nucleus.

¨       Most organisms have two genes for each trait, one on each of the homologous chromosomes in the cell nucleus.

 

D 10.       Explain how meiosis contributes to the genetic variability of organisms.

D 11.       Use the Punnet Square technique to predict the distribution of traits in mono- and di-hybrid crossings.

D 12.       Deduce the probable mode of inheritance of traits (e.g., recessive/dominant, sex-linked) from pedigree diagrams showing phenotypes.

D 13.       Describe the difference between genetic disorders and infectious diseases.

Heredity and Evolution – What processes are responsible for life’s unity and diversity?

10.5 - Evolution and biodiversity are the result of genetic changes that occur over time in constantly changing environments.

¨       Mutations and recombination of genes create genetic variability in populations.

¨       Changes in the environment may result in the selection of organisms that are better able to survive and reproduce. 

 

 

D 14.       Explain how the processes of genetic mutation and natural selection are related to the evolution of species.

D 15.       Explain how the current theory of evolution provides a scientific explanation for fossil records of ancient life forms.

D 16.       Describe how structural and behavioral adaptations increase the chances for organisms to survive in their environments.

 

Science and Technology in Society – How do science and technology affect the quality of our lives?

10.6 - Living organisms have the capability of producing populations of unlimited size, but the environment can support only a limited number of individuals from each species.

¨       Human populations grow due to advances in agriculture, medicine, construction and the use of energy.

¨       Humans modify ecosystems as a result of rapid population growth, use of technology and consumption of resources.

 

D 17.       Describe the factors that affect the carrying capacity of the environment.

D 18.       Explain how change in population density is affected by emigration, immigration, birth rate and death rate, and relate these factors to the exponential growth of human populations.

D 19.       Explain how technological advances have affected the size and growth rate of human populations throughout history.
