Bio module one study guide
What are the five basic themes in biology
-Biological systems interact -Structure and function are inter-related -Information must be transferred -Life depends on a continuous input and transfer of energy -Populations change over time through the process of evolution
All members of the same species occupying the same area at the same time constitute a
Population
By definition an organism this is eukaryotic
Possesses a nucleus
In deductive reasoning we begin with Blake and make blank based on that information
Premises and conclusions
Which sequence represents the pattern of energy flow within an ecosystem
Producers consumers and decomposers
Which cells do not have a nucleus or other membrane enclosed organelles
Prokaryotic cells
You discover an organism that is eukaryotic unicellular and photosynthetic based on this evidence to which group would you assign this organism
Protists
The human body is made up of specialize cells that perform different functions for example a neuron is a special cell of the nervous system receives and transmit signals throughout the body to perform these tasks the neuron uniquely possess posses branch protoplasmic protrusion call dendrites and axons which conduct a signal to and from it's so funny this illustrate which of the five major biological themes
Interrelation of structure and function and biological system
Which is a characteristics a good hypothesis
It is falsifiable
All of the genes present in a population make up its gene pool
True
Changing your view of reality involves a paradigm shift
True
Information in living organisms is transmitted by which mechanism(s)?
genes, hormones, neurotransmitters
Similar families of organisms our next group together in the same
Order
What are units of hereditary information
genes
DNA molecule is made up of
nucleotides
Which statement best describes the autotrophic organisms
Autotroph synthesize macromolecules from CO2 water and energy
What is a distinct characteristic of asexual reproduction
A cell splittling into identical halves
When tissues organize they form
An organ
Consider the statement biological systems what does this mean
Biological organisms are interdependent
Adaptive involves changes in ecosystem rather than an individual organism
False
An organism that reproduces asexually produces genetically variable offspring
False
I falsifiable hypothesis cannot be tested
False
The scientific name for coffee is coffea aribaca more specifically the species name is Arabica
False
The two domains of prokaryotes are bacteria and fungi
False
An organism that is neither prokaryotic nor photosynthetic and must obtain its nutrients by secreting digestive enzymes into the environment belongs to which group of organisms
Fungi
The correct example bread mold chimpanzee Oak tree Prokaryotes unicellular eukaryotes
Fungi animal plants bacteria protists
Primary purpose of homeostasis is to
Maintain a constant internal environment
Using the linnaean system of nomenclature corn is called Zea mays what is the specific epithet in this name
Mays
In living organisms chemical reactions responsible for growth and repair and nutrition or collectively referred to as
Metabolism
Which scenario best describes a double blind study
Neither the investigator nor the subjects know who is the experimental or control group
What's deductive reasoning to draw conclusions from specific observations
No
What is a byproduct of photosynthesis
Oxygen
Which organizational unit includes the few species of organisms
Population
Which process is most directly associated with the theory of evolution
Populations changing over time
Suppose we want to examine the effect of fertilizer on the size of zucchini producers and therefore we need to establish the experimental and control groups to control groups for this experiment would be defined under which conditions
Soil water sun and zucchini seeds
What is a subspecialty of systematics in the science of naming and classifying organisms
Taxonomy
Which is the benefit of sexual reproduction over asexual reproduction
The interaction of the genes from both parents allow genetic variation
What is the purpose of cilia and flagella of cells
They provide music for the cell
Darien experiment what is the purpose of a control group
To ensure that the results observed in the experimental group is due to the variable being tested
Which stimulus most directly cause the Venus fly trap to catch an insect
Touch
Which she has used to successfully do you activate specific human please modify use for bio fuel production and modify agricultural crops
CRISPR/Cas9
Suppose a particular Pro Tien is produced INXS of yourselves means what kind of mechanism will intervene to stop production
Homeostatic
CRISPR research can decrease the spread of what type of disease
Zika and other mosquito borne diseases
What statement best describes biology
the science of life
What is an end product of cellular respiration
Carbon dioxide
Which phylum to humans belong
Chordata
What type of molecule carries the hereditary info of an organism
DNA
Which describes a result of sexual reproduction
2 sex cells combine to form a fertilized cell
What would be the ultimate effect of an ecosystem if decomposers were eliminated
All life would eventually cease as nutrients would no longer be available
Which statement best describes the cell theory
All living organisms are composed of basic units called cells
What is the smallest chemical unit that retains the characteristic properties of a given element
Atom
Which statement concerning a scientific Theory is false
It is unchangeable
