BIO 201 Exam 1 (Frampton, UNCW)
the scientific study of life - correct answer Biology
atoms, molecules and macromolecules, cells, tissues, organs, organisms, population,
community, ecosystem, biosphere - correct answer Levels of Organization
cells and organization, energy and metabolism, response to environmental changes, regulation
and homeostasis, grown and developments, reproduction, biological evolution - correct answer
Key Features of Life
enclosed by a membrane and use DNA - correct answer All Cells
has membrane-enclosed organelles
- plants, animals, fungi - correct answer Eukaryotic Cell
simpler and smaller, does not contain a nucleus or other membrane-enclosed organelles -
correct answer Prokaryotic Cell
as more product accumulates, the process that creates it slows and less of the product is
created - correct answer Negative Feedback
as more of a product accumulates, the process that creates it speeds up and more of the
product is produced - correct answer Positive Feedback
discovery science, hypothesis-based science - correct answer Two Main Types of Scientific
Inquiry
describes natural structures and processes, based on observation and the analysis of data -
correct answer Discovery Science
a tentative answer to a well-framed question - correct answer Hypothesis
broader in scope than a hypothesis, general and can lead to new testable hypotheses,
supported by a large body of evidence in comparison to a hypothesis - correct answer A Theory
Is
consists of chemical elements in pure form and in combinations called compounds
- anything that takes up space and has mass - correct answer Matter
substance that cannot be brown down to there substances by chemical reactions - correct
answer Element
substance consisting of two or more elements in a fixed ratio
- has characteristics different from those of its elements - correct answer Compound
, carbon, hydrogen, oxygen, and nitrogen
- 95% of matter
calcium, phosphorus, potassium, and sulfur
-4%
remaining amount are trace elements - correct answer Essential Elements
the smallest unit of matter that still retains the properties of an element
- each element consists of unique atoms - correct answer Atom
no electric charge - correct answer Neutron
positively charged particle
- determines the elements atomic number - correct answer Proton
negatively charged particle - correct answer Electron
sum of the protons plus neutrons in the nucleus - correct answer Mass Number
two atoms of an element that differ in number of neutrons
- applications: dating fossils, tracing atoms through metabolic processes, diagnosing medical
disorders - correct answer Isotopes
the capacity to cause change - correct answer Energy
the energy that matter has because of its location or structure - correct answer Potential
Energy
covalent & ionic (strongest), hydrogen (weakest) - correct answer 3 Types of Bonding
the sharing of a pair of valence electrons by two atoms in a covalent bond, the sacred electrons
count as part of each atom's valence shell
- atoms are stable when their outermost shell is full
- can form between atoms of the same or different elements - correct answer Covalent Bond
bonding capacity
- the number of unpaired shared electors required to complete the valence shell - correct
answer Valence
an atom's attraction for electrons in a covalent bond
- the more electronegative an atom, the more strongly it pulls shared electrons to itself -
correct answer Electronegativity
