Penn Foster Vet Tech Biology Questions with correct
answers
Biology Correct Answer-is the scientific study of life.
cell Correct Answer-The smallest unit of biological organization that
display's all of the characteristics of life
Natural selection Correct Answer-The process by which a population
develops adaptations to its environment and evolves over time
Four conditions needed for natural selection: Correct Answer-1.
Population members exhibit differences that are heritable
2. Members produce more offspring than can be supported by
environmental resources
3. Competition for limited resources
4. Through many generations a greater portion of the population exhibits
adaptations to the environment
Taxonomy Correct Answer-The science of classifying organisms into
groups based on how they are related
Binomial name Correct Answer-Two part scientific name that consists
of genus and species
Three Domains Correct Answer-Archaea, Bacteria, Eukarya
,Domain Archaea Correct Answer-Prokaryotic, unicellular organisms
that live in extreme habitats
Domain Bacteria Correct Answer-Prokaryotic, unicellular bacteria
Domain Eukarya Correct Answer-Four Kingdoms- protists, fungi,
plants, animals
Kingdom Protista Correct Answer-Unicellular, multicellular, or colonial
organisms. More complex than prokaryotes
Kingdom Fungi Correct Answer-Eukaryotic, multicellular organisms
that break down dead organic debris for sustenance
Kingdom Plantae Correct Answer-Multicellular, eukaryotic organisms
with vascular tissues that use photosynthesis to produce energy
Kingdom Animalia Correct Answer-Eukaryotic, multicellular organisms
that do not produce their own nutrients
Photosynthesis Correct Answer-Process of using sunlight to synthesize
sugars from raw materials
,Scientific Method Correct Answer-Used by scientists to guide research
and gain a better understanding of natural phenomena
Test group Correct Answer-Group provided with experimental variable
in an experiment
Control group Correct Answer-Test group not given experimental
variable in an experiment
Scientific Theory Correct Answer-Widely accepted explanation for a
natural phenomenon
Reproductive cells Correct Answer-Gamete producing cells
Somatic cells Correct Answer-Any cell other than a reproductive cell
Mitosis Correct Answer-Process of division for somatic cells
Meiosis Correct Answer-Process of division for reproductive cells
Daughter cells Correct Answer-Genetically identical cells, result of
mitosis
Gametes Correct Answer-Cells for sexual reproduction, half the number
of chromosomes, result of meiosis
, Cell cycle Correct Answer-Two stages: interphase and mitosis
Interphase Correct Answer-Longest portion of the cell cycle, growth and
DNA duplication
G1 phase of the cell cycle Correct Answer-First phase, the cell grows
and builds proteins, carbs and lipids
S (synthesis) phase of cell cycle Correct Answer-Second phase of cell
cycle, DNA is replicated to prepare for nuclear division. After DNA
replication, chromatids attach to their copy by a centromere. Results in
two identical sister chromatids.
G2 phase of cell cycle Correct Answer-Third phase, growth phase, cell
produces proteins necessary for mitosis and prepares to divide.
Cytokinesis Correct Answer-Division of the cytoplasm, occurs at the
end of mitosis during telophase
Apoptosis Correct Answer-Programmed chemical process for a cell to
self destruct.
Cancer Correct Answer-Disease of the cell cycle
