From Embryology

Draft Pages

9.3 Blueprint of Life

1. Evidence of evolution suggests that the mechanisms of inheritance, accompanied by selection, allow change over many generations

describe, using specific examples, how the theory of evolution is supported by the following areas of study:

  • comparative embryology
  • comparative anatomy
  • biochemistry

Other Areas

3. Chromosomal structure provides the key to inheritance

  • explain the relationship between the structure and behaviour of chromosomes during meiosis and the inheritance of genes
  • explain the role of gamete formation and sexual reproduction in variability of offspring
  • describe the inheritance of sex-linked genes, and alleles that exhibit co-dominance and explain why these do not produce simple Mendelian ratios
  • describe the work of Morgan that led to the understanding of sex linkage
  • explain the relationship between homozygous and heterozygous genotypes and the resulting phenotypes in examples of co-dominance
  • outline ways in which the environment may affect the expression of a gene in an individual

5. Current reproductive technologies and genetic engineering have the potential to alter the path of evolution

identify how the following current reproductive techniques may alter the genetic composition of a population:

  • artificial insemination
  • artificial pollination
  • cloning

5. MacFarlane Burnet’s work in the middle of the twentieth century contributed to a better understanding of the immune response and the effectiveness of immunisation programs

identify the components of the immune response

  • antibodies
  • T cells
  • B cells

6. Animals that produce vibrations also have organs to detect vibrations

describe the anatomy and function of the human ear, including:

  • pinna
  • tympanic membrane
  • ear ossicles
  • oval window – round window – cochlea
  • organ of Corti – auditory nerve

NSW HSC - Biology

Students will develop

knowledge and understanding of: further skills in:
  1. the history of biology
  2. the nature and practice of biology
  3. applications and uses of biology
  4. the implications of biology for society and the environment
  5. current issues, research and developments in biology
  6. cell ultrastructure and processes
  7. biological diversity
  8. environmental interactions
  9. mechanisms of inheritance
  10. biological evolution.
  1. planning investigations
  2. conducting investigations
  3. communicating information and understanding
  4. developing scientific thinking and problem-solving techniques
  5. working individually and in teams.

Students will develop positive values about and attitudes towards: themselves, others, learning as a lifelong process, biology and the environment.

8.3 Patterns in Nature

Refer to the Science Years 7–10 Syllabus for the following: 5.7.3c) construct word equations from observations and written descriptions of a range of chemical reactions

5.8.1a) explain that systems in multicellular organisms serve the needs of cells

5.8.1b) identify the role of cell division in growth, repair and reproduction in multicellular organisms

5.8.2c) identify that information is transferred as DNA on chromosomes when cells reproduce themselves

5.8.2d) identify that genes are part of DNA.

Domain: knowledge and understanding

1. Organisms are made of cells that have similar structural characteristics

  • outline the historical development of the cell theory, in particular, the contributions of Robert Hooke and Robert Brown.
  • describe evidence to support the cell theory
  • discuss the significance of technological advances to developments in the cell theory
  • identify cell organelles seen with current light and electron microscopes
  • describe the relationship between the structure of cell organelles and their function
  • process information from secondary sources to analyse electron micrographs of cells and identify mitochondria, chloroplasts, Golgi bodies, lysosomes, endoplasmic reticulum, ribosomes, nucleus, nucleolus and cell membranes

5. Maintenance of organisms requires growth and repair

  • identify mitosis as a process of nuclear division and explain its role
  • identify the sites of mitosis in plants, insects and mammals
  • explain the need for cytokinesis in cell division
  • identify that nuclei, mitochondria and chloroplasts contain DNA
