Questions and Answers 100% Correct
Mitochondria -rod-shaped organelles that provide cells and thus the body with energy
-site of cellular respiration in which substances, primarily gluclose, are converted in the presence
of oxygen to adenosine triphosphate ATP which provides energy for cellular activites
photosynthesis process by which plants, and some other organisms, use solar energy to
convert water H20 and carbon dioxide C02 into surgars that can be used to proivde energy to
cells. This process gives off oxygen as a waste product
animal cells eukaryotic cells with complex structures within membranes that separate
interior and exterior of the cells. Contains a cytoplasm with cell membranes as well as ribosomes
that make proteins from amino acids
plant cells same as animal except it has a rigid cell wall outside the cell membrane that
provides structural support and protection to the cell
pesticide resistance results from adaptation of organisms to a pesticide are likely to
survive and pass on that genetic trait to their offspring
,chemical bonding happens during the formation of molecular compounds through
covalent and ionic bonding
ionic bonds transfer of electrons between molecules
covalent bonds sharing of electrons between molecules
when salt is dissolved in water it forms sodium and choloride ions that beocme
essentially surrounded by water molecules. The volume of water does not increase but the mass
of the solution increases which also increases density
weight - physics force created when a mass is acted upon by gravity
momentum - physics product of mass and velocity - not related to inertia
mass - physics both a measure of quantity of matter in an object and a measure of an
objects resistance to changing its state of motion when acted upon by an outside force
, acceleration - physics rate of an objects change in velocity over time
Isaac Newton's law of inertia states than an object will continue in its state of rest or
motion unless acted upon by an outside force
temperature - physics measure of the average kinetic movement energy of the molecules
in a substnace. At higher temperatures molecules move faster
evaporation and precipitation - physics evaporation is a cooling process while
precipitation is a heating process. The total amount of atmospheric water vapor remains
relatively constant, meaning that precipitation amounts offset water vapor added by evaporation
and transipitation
weathering of rocks in northeasters U.S. The cycling freezing and thawing f water that
has seeped into fractures in rock outcrops is known as frost wedging. This is a major agent pf
physical weathering in cold climates. As water freezed it expands and increased the size of the
fracture, eventually helping break the rock apart over many years
