Questions and Answers

What unique property of water allows ice to float above liquid water?

Ice floats above liquid water due to the fact that it is less dense than liquid water, which is a result of the hydrogen bonds in the water molecules.

What is the capacity of water to absorb energy called?

The capacity of water to absorb energy is called specific heat capacity, which is higher than that of other solvents such as ethanol.

What is the pH of pure water?

The pH of pure water is neutral, as the number of hydrogen ions balances the number of hydroxyl ions.

Study Notes

History and Chemical Basis of Biology

  • The history of biology traces back to ancient Egypt and Mesopotamia, with significant contributions from Greek philosophers like Aristotle and Theophrastus.
  • Islamic scholars in the medieval period made significant contributions to the study of biology, particularly in the fields of medicine and natural history.
  • The development of biology was greatly influenced by the improvement of the microscope by Anton van Leeuwenhoek, leading to discoveries in microscopic life.
  • In the 19th century, the importance of the cell was emphasized, and the cell theory was consolidated, focusing on the fundamental unit of organisms.
  • Taxonomy and classification became a key focus, with Carl Linnaeus publishing a basic taxonomy and Georges-Louis Leclerc proposing the possibility of common descent.
  • Evolutionary thinking began with Jean-Baptiste Lamarck and was further developed by Charles Darwin and Alfred Russel Wallace, leading to the theory of natural selection.
  • The modern synthesis in the early 20th century reconciled Darwinian evolution with classical genetics, laying the foundation for modern genetics.
  • The discovery of DNA as the component of chromosomes and the double-helical structure of DNA marked the transition to the era of molecular genetics in the 1950s.
  • The genetic code was cracked in the 1960s, and the Human Genome Project was launched in 1990 to map the human genome.
  • All organisms are composed of chemical elements, with oxygen, carbon, hydrogen, and nitrogen accounting for most of the mass, and water being fundamental to life.
  • Biochemistry and molecular biology seek to understand the chemical processes and molecular basis of biological activity in organisms.
