    • Acids
      A group of chemicals with similar properties, e.g. they all taste sour
    • Acids
      • Lemon juice
      • Vinegar
      • Milk
    • Alkalis
      Chemically opposite to acids, when dissolved in water they are called alkalis, they have similar properties like feeling soapy
    • Alkalis
      • Baking powder
      • Soap
      • Bleach
    • Neutral substances

      Substances which are neither an acid nor an alkali
    • Neutral substance

      • Water
    • Concentration
      Acids and alkalis come in different concentrations e.g. 1M or 0.1M, the higher the number the stronger the substance, it tells you how many particles are dissolved in one litre of water
    • Concentrated solutions
      Will be labelled with a corrosive hazard label - telling you to wear goggles when using them
    • Indicators
      Chemicals which can be used to identify whether a substance is acidic or alkaline because they change colour, e.g. red cabbage water, litmus, Universal Indicator
    • Universal indicator and the pH scale
    • Bones
      • Protect organs (e.g. the skull protects the lung)
      • Support your body (e.g. the vertebrae in your back hold you up straight)
      • Allow you to move using muscles as you walk
      • Hard (to withstand force and pressure)
      • Light (so they are easy to move)
      • Contain bone marrow where blood cells are made
      • Muscles attach to and move bones
    • Big cock to f
    • Endocrine glands include the pituitary gland, thyroid gland, parathyroid glands, adrenal glands (including the adrenal medulla), pancreas, ovaries/testes, and pineal gland.
    • Glucose, amino acids and vitamins are actively transported back into the blood by the proximal convoluted tubule
    • Glucose, amino acids and vitamins are actively transported back into the blood by the proximal convoluted tubule
    • Skeletal muscles attach to bones via tendons and allow voluntary movement.
    • The main function of the endocrine system is to secrete hormones into the bloodstream, which then travel throughout the body.
    • Hormones are chemical messengers that regulate various physiological processes such as growth, metabolism, reproduction, and homeostasis.
