UA BSC-108 questions and answers
What is Biology? study of life
What are the 3 domains? Eukarya, Bacteria, Archae
What are the 4 kingdoms in Eukarya? Plantae, Fungi, Animalia, Protists
What are the properties of life? order, regulation, grow & develop, use energy, respond to
environ., reproduce, evolve
How do you define something as living? by what they do
What are some common themes in biology? ...
What is the scientific method? Know the components of it. observation, question, hypothesis,
experiment, collect data, conclusion
What is a hypothesis? Tentative answers to a well framed questions
What are the components of a good hypothesis? be specific, "if, then" statements, testable
What is a theory in science? they are supported by an accumulation of extensive and varied
evidence (from multiple hypotheses).
What is an atom? is smallest unit of an element that has all its properties
What is an atom composed of? protons, neutrons, electrons
, What is an ion? a charged atom
What is the difference between an ion and isotope? ion is a charged atom and isotope is an atom
ith irregular number of nuetrons
What is the association between isotopes and fossils? ...
What is energy? capacity to do work, make a change in matter
What is a neutral atom? #protons = #electrons
What is a trace element? ...
What is a radioactive isotope? The nucleus decays, giving off particles and energy.
How many electrons are found in the first energy shell? Second? Third? 2
What is the difference between atomic number and atomic mass? atomin number is how many
protons, atomic mass is how many neutrons + protons
What are the different types of chemical bonds? ionic, covalent, hydrogen
How are they formed? ionic is formed by one atom giving or receiving one electron, covalent is
sharing electron(s), & hydrogen is unequal sharing of electrons
Which bond is the strongest, weakest? ionic=strong, covalent=middle, hydrogen=weak
How does the hydrogen bond contribute to the properties of water? bonds are weak and are
broken and reformed constantly
