BSC Exam 1 PASSED Exam Questions and
CORRECT Answers
(hierarchy of structures and
emergent properties) - CORRECT ANSWER-✔✔ the order of the levels of biological
organization
Order, Evolutionary adaptation, Response to the environment, Regulation, Energy
Processing, Reproduction, Growth and Development. - CORRECT ANSWER-✔✔ the
properties of life
The process of maintaining a stable internal environment. - CORRECT ANSWER-✔✔
Homeostasis - definition
Asexual Reproduction
Def: Reproduction requiring only one parent/genetic source
binary fission, parthenogenesis, budding
PRO: Quick, Low Requirements, CON: Low Genetic Variety
Sexual Reproduction
Def: Reproduction requiring two parents/genetic sources
conjugation, fertilization
PRO: Genetic Variety,CON: Need water, partners, GAMETES - CORRECT ANSWER-✔✔
Asexual vs. Sexual Reproduction
1 define the problem, 2 collect information about the problem, 3 form a hypothesis, 4
experiment to test the hypothesis, 5 make observation and record data, 6 draw a conclusion, 7
publicize the results - CORRECT ANSWER-✔✔ The steps of the scientific method
the experimental factor that is manipulated; the variable whose effect is being studied -
CORRECT ANSWER-✔✔ Independent variable
Indep - typically the variable being manipulated or changed. Dep - is the observed result of
the independent variable being manipulated. Remember teacher offering insentive of $5 to
, pass test. Bride of money is the independent students performance of reading test is the
dependent - CORRECT ANSWER-✔✔ Independent vs. dependent variable
the smallest unit of matter that has the characteristics of an element; consists of three main
types of subatomic particles: protons neutrons and electrons. - CORRECT ANSWER-✔✔
Atoms
the characteristic number of protons per atom of an element used as an identifying
attribute.(= # of protons) - CORRECT ANSWER-✔✔ Atomic number
Given protons and mass number, find neutrons.(= protons + neutrons) - CORRECT
ANSWER-✔✔ Mass Number
(have different number of neutrons resulting in a different mass number
but same atomic number), **atoms of the same element that have different numbers of
neutrons** - CORRECT ANSWER-✔✔ Isotopes
a. 1st energy level or shell: 1 orbital = 2 electrons
b. 2nd and 3rd energy levels or shells: 4 orbitals = 8 electrons - CORRECT ANSWER-✔✔
Orbitals and energy levels (electrons) - there are 2 electrons per orbital
a bond in which electrons are shared - CORRECT ANSWER-✔✔ Covalent bond - definition
Share electrons, Some Polar, Nonmetal and nonmetal, Nonpolar both atoms of same elements
- CORRECT ANSWER-✔✔ Covalent bond properties
transfer of electrons, gain electron become -, loss electron become + - CORRECT ANSWER-
✔✔ Ionic bond definition
Neutral, Cation and anion, Metal and nonmetal, Dissolve in H2O, Conduct electricity when
dissolve in water, High melting points and boiling points, Solids at room temperature,
Translate lattice - CORRECT ANSWER-✔✔ ionic bond properties
