BIOL 111 Chapters 1, 2, and 3 (Dr.Xie)
TAMU Latest Exam Fully Solved.
What is natural science? - Answer field of science that is related to the physical world and its
phenomena and processes
What is biology? - Answer the study of living things and life
basic science - Answer the pursuit of knowledge about natural phenomena for its own sake
applied science - Answer form of science that aims to solve real-world problems
What are the shared characteristics of the natural sciences? - Answer scientific reasoning and
scienctific methods
scientific reasoning - Answer the way scientists think
scientific methods - Answer the way scientists conduct research
types of scientific inquiry - Answer discovery and hypothesis based
the scientific method - Answer A series of steps followed to solve problems including
collecting data, formulating a hypothesis, testing the hypothesis, and stating conclusions.
How is a theory different from a hypothesis? - Answer defined as a hypothesis that has been
repeatedly tested and not yet falsified
cell theory - Answer idea that all living things are composed of cells, cells are the basic units
of structure and function in living things, and new cells are produced from existing cells
gene theory - Answer Genes are the basic units of inheritance and are comprised of DNA,
provides the foundation for the field of genetics
Theory of Heredity - Answer Genes, located on chromosomes, are passed down from parent
to offspring, Diploids (2n) get two copies of each chromosome: one from mom, one from dad,
Different versions of the same gene, "alleles", exist and cause variation, Mutations/crossing over
during reproduction also produce variation, An individual can pass on a trait that they do not
express
, Theory of Evolution - Answer Many philosophers and scientists proposed ideas relating to
observable changes in organisms
what are the functional traits of life? - Answer 1. growth
2. reproduction
3. homeostasis
4. sense and respond to stimuli
5. obtain and use energy
6.evolutionary adaptation
7.order
noncellular - Answer lack almost all cell components (e.g. organelles, ribosomes, and
membranes)
size of viruses - Answer 20-200 nm
what are viruses made of? - Answer Made of nucleic acid core, capsid, and sometimes outer
envelope
What are emergent properties? - Answer New properties that arise with each step upward in
the hierarchy of life, owing to the arrangement and interactions of parts as complexity
increases.
the levels of organization among living things - Answer atom, molecule, organelles, cells,
tissues, organs, organ systems, organisms, populations, communities, ecosystems, the
biosphere.
How do prokaryotes reproduce? - Answer binary fission
chromosome structure of prokaryotes - Answer circular
size of prokaryotes - Answer .1 um - 5 um
Chromosome Structure in Eukaryotes - Answer linear
How do eukaryotes reproduce? - Answer mitosis and meiosis
