Clay particles in clay soil contain layered aluminum and iron compounds that determine that pattern of
adjacent layers. This technically is a "self-replicating molecular assemblage" which could be argued as a
way to define life. - ✔✔Clay is not living because this formation is a simple repetitive process and is
without other characteristics of life, such as the ability to evolve or metabolize or respond to the
environment.
Life is organized in a hierarchical fashion. Which of the following sequences correctly lists that hierarchy
as it increases in complexity? - ✔✔Molecule, cell, tissue, organ, organ system, organism, population,
community, ecosystem
The ultimate source of energy flowing into nearly all ecosystems is ____. - ✔✔The sun
Community - ✔✔All organisms living in a general area.
A common objective in scientific methodologies is to try to - ✔✔determine whether there is a
relationship between variables.
To be scientifically valid, a hypothesis must be - ✔✔testable and falsifiable.
The forelimbs of whales are broad and flipper-like, which makes them suitable for swimming. The
forelimbs of primates include digits with dexterity and have opposable thumbs, making them suitable for
grasping and manipulating. This illustrates - ✔✔a result of evolution (by natural selection) AND the
connection between form and function.
Living systems: - ✔✔are NOT always composed of many cells
maintain a relatively constant internal environment
respond to changes in the environment
, use DNA as the master hereditary molecule
grow, develop, and eventually die
Characteristics of living things - ✔✔a complex but discernible organizational pattern
the ability to take in energy and use it
the ability to respond to stimuli
the ability to reproduce
In an experimental design, the best way to determine whether results are consistent and therefore
viable, is to use - ✔✔replication
In biology, the unity and diversity of life - ✔✔unites biology as a scientific discipline
is explained by evolution
describes both similarities and differences extending across all species
The hydrogen atoms of a water molecule are bonded to the oxygen atom of that same molecule by
______ whereas neighboring water molecules are held together by _______ bonds. - ✔✔polar covalent;
hydrogen
All organisms (biotic factors) in a self-sustaining natural setting plus their physical environment (abiotic
factors) constitutes an - ✔✔ecosystem
________ is a variation in form, function, or behavior which increases the level to which an organism is
suited to its environment. - ✔✔Adaptation
Science - ✔✔has improved human welfare by the discovery of antibiotics
helps us to understand cancer mechanisms
is NOT a basis for all ethical or moral decisions
can ease the feeding of the world population by producing new plant strains
