Define and be able to recognize emergent properties. - Answer✔️✔️-
Emergent Properties: Quality that results from interactions of a systems
components
Understand the basis of homeostasis. Using sweat as an example, how does
sweating return body temperature to a normal range? - Answer✔️✔️-
Maintenance of internal constancy
- the body regulates itself
Define autotroph and heterotroph and be prepared to use contextual clues
to identify the way a given organism acquires energy. - Answer✔️✔️-
Autotroph: Produces extract energy & nutrients from the non-living
environment
Heterotroph: Consumers obtain energy & nutrients by eating other
organisms
There are six steps are involved in the scientific process. What are they and
give an example of each? - Answer✔️✔️-1) problem
Biology 1320 :Texas State University
6) conclusion
Scientifically, know the difference between a hypothesis and a theory. -
Answer✔️✔️-Hypothesis is an educated guess
Theory is an explanation about something in the natural world. (has been
repeatedly tested and uses facts to explain the natural world)
Chapter 2: Define energy and matter - Answer✔️✔️-Energy: The ability to do
work
Matter: anything that takes up space. ex: organisms rocks the ocean
Define an atom, including the three subatomic particles that comprise it.
What is the structure of the atom and the charges of those particles? -
Answer✔️✔️-Atom: the smallest possible "piece" of an element that retains
the characteristics of the element.
-proton=positive charge
-neutron=neutral charge
-electron=negative charge
What is an element? - Answer✔️✔️-a pure substance that cannot be broken
down by chemical means into other substances
What is the difference between atomic number and atomic mass? -
Answer✔️✔️-Atomic Number: the number of protons in the nucleus
Atomic Mass: the number of protons and neutrons in the nucleus
Biology 1320 :Texas State University
What is an isotope? - Answer✔️✔️-Atoms of the same element that have
different numbers of neutrons
How many electrons reside a complete innermost electron shell, how many
reside in complete outer shells? - Answer✔️✔️-innermost=2
outermost=8
What makes an atom inert? - Answer✔️✔️-with a filled outer valence shell
an inert atom is not able to gain or lose an electron and therefore is not able
to participate in any chemical reactions. they are very stable
What is a molecule? - Answer✔️✔️-a group of atoms bonded together,
representing the smallest fundamental unit of a chemical compound that
can take part in a chemical reaction
How many pairs of electrons are shared in a single covalent bond? -
Answer✔️✔️-2
Define and know the difference between polar covalent, nonpolar covalent,
ionic, and hydrogen bonds.
Have a clear grasp on what is happening with electrons in each. -
Answer✔️✔️-Polar Covalent Bond: a lopsided union, one nucleus exerts as a
much stronger pull on the shared electron that does the other nucleus.
shares electrons-unequally with less electronegative partner
