ANSWERS (VERIFIED ANSWERS) ALREADY GRADED A+
What is positive feedback? - ANSWERS-An end product speeds up its own production.
What is negative feedback? - ANSWERS-Accumulation of the end product slows its production.
What is an example of positive feedback? - ANSWERS-The increasing labor contractions of
childbirth before delivery.
Which of these is reflective of the hierarchical organization of life from most to least inclusive? -
ANSWERS-kingdom, phylum, class, order, family, genus, species
A controlled experiment is one in where - ANSWERS-there are at least two groups, one of which
does not receive the experimental treatment.
A substance that cannot be broken down into other substances by ordinary chemical
procedures is a(n) - ANSWERS-element.
A substance that consists of two or more substances in a fixed ratio is a - ANSWERS-compound.
Which of the following subatomic particles always has a positive charge? - ANSWERS-proton
,Which statement is true of all atoms that are anions? - ANSWERS-The atom has more electrons
than protons.
Subatomic particles that have no electrical charge and are located in the atomic nucleus are -
ANSWERS-neutrons
Two atoms of an element that differ in number of neutrons are - ANSWERS-isotopes.
Isotopes of an element are similar in the sense that they have the same - ANSWERS-number of
protons.
Isotopes of an element differ in the sense that they have a different - ANSWERS-number of
neutrons.
A sharing of a pair of valence electrons by two atoms is referred to as a - ANSWERS-covalent
bond.
Atoms that have an *equal* sharing of a pair of valence electrons is called a - ANSWERS-
nonpolar covalent bond.
Atoms that have an *unequal* sharing of a pair of valence electrons is called a - ANSWERS-polar
covalent bond.
Energy that matter possess due to location or its structure is known as - ANSWERS-potential
energy.
When a cation and anion are attracted to each other, this is known as a(n) - ANSWERS-ionic
bond.
, The attraction between a hydrogen covalently bonded to one electronegative atom and another
electronegative atom is called a - ANSWERS-hydrogen bond
Electrons are not evenly distributed; at any instant, they may accumulate by chance in one part
of a molecule or another, causing every-changing regions of positive and negative charge that
enable all atoms and molecules to stick to one another, known as - ANSWERS-Van der Waals
interactions.
Capacity to cause change is known as - ANSWERS-energy
Example of potential energy? - ANSWERS-Molecule of glucose.
In the case of H20, the oxygen atom covalently bonds unequally with 2 hydrogen atoms. This is
why H20 is considered a _______ molecule. - ANSWERS-polar
Water molecules are capable of bonding with four neighboring water molecules because -
ANSWERS-surrounding oxygen atoms are constantly bonding with other surrounding hydrogen
atoms, which are simultaneously bonded to another oxygen atom.
What contributes to the transport of water up plants against gravity? - ANSWERS-Cohesion
Attraction between water and another substance (for example, between water and plant cell
wall) is known as - ANSWERS-Adhesion
A spider walking on water is an example at water's high - ANSWERS-surface tension.
By absorbing heat from air that is warmer, and releasing stored heat to cooler air, water is -
ANSWERS-moderating air temperature.
