What is the key limiting factor on cell size?
ANSWER-The size of a cell is limited by the ratio of its surface area to volume.
A cell will only remain stable if...
ANSWER...the surface area of the plasma membrane maintains a balance with the volume of the
cytoplasm.
The salivary gland...
ANSWER...secretes saliva which enters the digestive tract and aids the digestive process.
Gregor Medel
ANSWER-Studied the relationships between traits expressed in parents and offspring and the genes that
caused the traits to be expressed.
In order to become an established part of an island ecosystem there must be...
ANSWER...a populations large enough to ensure successful reproduction, a food source, a suitable
habitat, and a source of moisture.
,Lymphocytes
ANSWER-Are cells involved in immunity and are produced in bone marrow as stem cells.
B Cells
ANSWER-Produce antibodies into the bloodstream that find and attach themselves to foreign antigens
(toxins, bacteria).
T Cells
ANSWER-Some patrol the blood for antigens, but are also equipped to destroy antigens. They may
regulate immune responses as well.
Mass extinctions promote diversification...
ANSWER-...because ecological niches open up, making conditions favorable for the establishment of
new, diverse species.
Common elements found in proteins are
ANSWER-Carbon, Hydrogen, Oxygen, and Nitrogen
What phylum are snakes in?
ANSWER-Chordata
Cellular Respiration
ANSWER-Is the process that releases energy for use by the cell.
,A hydrogen bond
ANSWER-Is weaker than ionic, covalent, disulfide, or double bonds.
A hydrogen bond involves
ANSWER-the attraction of atoms of different polarity and can be easily broken.
Ionic bonds involve
ANSWER-the transfer of electrons.
Covalent bonds
ANSWER-share electrons.
Chimpanzees
ANSWER-Are more closely related to Homo Sapiens than to other apes, but Homo Sapiens did not
evolve from chimpanzees.
About five million years ago...
ANSWER...the lineage that led to the modern Homo Sapiens diverged from the lineage that led to the
modern chimpanzee.
The evolution leading to Homo Sapiens...
, ANSWER-Is more like branching out of a tree with dead ends and new branches appearing
simultaneously than like steps on a ladder.
Early hominids...
ANSWER-Stood upright before there was an increase in brain size.
The large brain and upright posture
ANSWER-of Homo Sapiens did not evolve together.
Most fossils of Hominids
ANSWER-are from continents other than North America.
The stomach secretes
ANSWER-digestive enzymes, hydrochloric acid, and gastric juices which aid in digestion. The mucous
secreted by the stomach protects the stomach lining from the acids and juices.
Algae and Protozoa belong to the kingdom
ANSWER-Protista
Plants and animals obtain usable nitrogen
ANSWER-through nitrogen fixing bacteria and lighting.
