The History Aluminium was first discovered in 1825‚ by early discoverer‚ Hans Christian Oersted in Denmark. Before this time‚ alum

PATTERNS IN NATURE – Summary Notes 1. ORGANISMS ARE MADE OF CELLS THAT HAVE SIMILAR STRUCTURAL CHARACTERISTICS 1.1 Outline the historical development of the cell theory‚ in particular‚ the contributions of Robert Hooke and Robert Brown The Cell Theory states that: All living things are made of cells (Theodor Schwann & Matthias Schleiden) Cells are the basic structural and functional unit of organisms (Theodor Schwann) All cells come from pre-existing cells (Rudolf Virchow) The historical

Structural Isomers • molecules with the same molecular formula but with different arrangements of atoms • differences in the shape of isomers lead to differences in their physical & chemical properties • For example‚ galactose‚ glucose and fructose have the same molecular formula (C₆H₁₂O₆) but different structures (figure 6 page 30) • glucose itself has 3 different structural isomers in dry state‚ glucose has a linear structure‚ but when dissolved in water‚ the molecules fold on itself

Evaluate the impact of care in the community for adults with Mental Health problems. Care in the community is where a patient is no longer detained nor sectioned within a hospital institution. However‚ there must be at least three practitioners agreeing that it is necessary for the patient to be released into the community. Adults who may suffer from mental health problems can ask to be cared for within the community. Patients and their families are now more educated with a sense of empowerment

The Scientific Study of Life Mastering Concepts: 1. What characteristics distinguish the living from the nonliving? The characteristics that distinguish the living from the nonliving are that nonliving things reproduce and grow‚ use energy‚ have levels of organization‚ maintain constant internal conditions‚ and evolve. 2.

Why a Bill of Rights and What Impact Does it Have? All have heard the saying‚ “Great minds think alike.” When many great minds of the colonies gathered to create a new government‚ two rarely thought exactly alike. The Bill of Rights was created through the kind of debate and exchange of ideas that it protects to this day. The Declaration of Independence states the purpose of government is to protect our basic human rights. This was one principle that all the Founders did agree on. But if
