QUESTIONS AND ANSWERS SURE A+
✔✔Auxin - ✔✔plant growth regulator or substance that promotes/influences the growth
& development of plants
-produced at sites where cells are dividing primarily in the shoot tips
-auxin like compounds may be produced synthetically
✔✔Auxin Transport Inhibitors - ✔✔class of selective herbicides that disrupt auxin
transport
-auxin transport obstruction causes unnatural concentration of auxin in meristematic
shoots & roots, disturbing the auxin tolerances req for normal plant growth
✔✔Back Feed - ✔✔electric flow in an unintended direction thru a process whereby de-
energized lines become energized from an external source----home generator
✔✔Bargaining Unit - ✔✔group of workers rep by a union local
✔✔Basal Application - ✔✔herbicide application made at the bottom 12 in of stem & root
collar with an herbicide in an oil carrier
✔✔Behavior-Based - ✔✔theory of industrial accident prevention pioneered by Herbert
Heinrich that considers the overwhelming majority of incidents to be caused by unsafe
acts
,✔✔Biological Methods - ✔✔management of vegetation by establishment & control of
compatible stable plant communities using plant competition, allelopathy, animals,
insects, pathogens
-cover-type conversion is a type of biological control
✔✔Border Zone - ✔✔section of a transmission/pipeline ROW that extends from
wire/pipe zone to the ROW edge
-managed to promote a low growing plant community of forms, tall shrubs & low
growing trees below a specified height(25 ft)
✔✔Branch Bark Ridge - ✔✔raised strip of bark at the top of a branch union where the
growth & expansion of trunk + parent stem & adjoining branch push the bark into the
ridge
✔✔Branch Collar - ✔✔area where a subdominant branch joins another branch or trunk
that is created by overlapping vascular tissue from both the branch & trunk
-typically enlarged at the base of the branch
✔✔Branch Removal Cut - ✔✔pruning cut the removes the smaller of two branches at a
union or parent stem, w/o cutting into the branch bark ridge or branch collar or leaving
stub
✔✔Branch Union - ✔✔point where a branch originates from the trunk or another branch
✔✔Brand - ✔✔name/service/trademark/color or attribute that distinguishes a prod or
service from competitors
✔✔Brush Cutter - ✔✔machine used to remove & grind saplings, small trees,
incompatible vegetation
✔✔Budget - ✔✔means to justify the allocation of resources, set priorities & make
decisions regarding what can/can't be accomplished
✔✔Bus Work - ✔✔rigid conductor----usually rectangular or hollow tube design
✔✔Business Continuity - ✔✔ability of an org to maintain essential function during &
after disaster
✔✔Capacitor - ✔✔electrical device used to correct power factors
-temporarily stores charge of electricity & returns it to restore a line balance
✔✔Capacitive Reactance - ✔✔charge that builds up btwn long parallel conductors
-portion of load slighly impedes current
, ✔✔Capital Budget - ✔✔monetary outlay for relatively large sums of money invested
over multiple years
✔✔Cascading Outage - ✔✔series of power interruptions on a transmission sys----one
interruption increases vulnerabilities & causes additional interruptions----causing further
interruptions-----results in widespread blackouts
✔✔Chain of Command - ✔✔series of administrative ranks, positions, etc
-each has direct authority over the one immediately below
✔✔Chemical Control Method - ✔✔control of undesirable vegetation thru the use of
herbicides & TGR
✔✔Chemical Pruning - ✔✔pruning that uses certain herbicides to. selectively control
targeted branches----typically applied along the side of ROW corridors
✔✔Chronic Toxicity - ✔✔damage to an organ sys by substance thru disruption of
biochemical pathways or enzymes in areas other than the point of contract
-delayed damage resulting from repeated exposure to low amounts of a substance over
long period a lifetime
✔✔Circuit - ✔✔electrical network consisting of a conductor or series of conductor thru
which electrical flow including. return path to the source
✔✔Circuit Breaker - ✔✔switch that automatically interrupts the flow of electricity if a
circuit becomes overloaded or dangerous prob occur
✔✔Circuit work - ✔✔completing all necessary line clearance on a feeder or circuit basis
✔✔Clearance - ✔✔amount of open space btw tree & another object, ground, person,
vehicle
-distance btwn tree & lines(equipment)
✔✔Closed Chain of Custody - ✔✔handling & use of ready to use & diluted concentrate
formulations in closed delivery systems
✔✔Codominant Stem/Branch - ✔✔forked branches nearly the same size in diameter
arising form a common junction----may have included bark
✔✔Combined-Cycle System - ✔✔electrical generation----process that captures heat
from exhaust from generation & uses it to create a steam to drive a second turbine
