◍ Bohr Effect chart (low pH).
Answer: C- High CO2H- High H+A- AcidicR-Release of O2(rt. Shift)T-
tense state (in tissues)
◍ Which level of protein structure is disrupted through the hydrolysis of
peptide bonds?QuaternaryTertiaryPrimarySecondary.
Answer: PrimaryThe primary structure of a protein is the sequence of amino
acids held together by peptide bonds. Peptide bonds are formed by
dehydration reactions and disrupted by hydrolysis.
◍ True or False: Nitrogen is called the superglue of the chemical world..
Answer: FALSE
◍ Car running up keep stopping why?.
Answer: Contact is not deenergizing in push button
◍ A Latching relay: Used for call registration,direction selection or as selector
relaysTwo types are: Set/Rest are electrical and Mechanical Latching relays

◍ True or False: Large elements, such as strontium, are common in
biomolecules..
Answer: FALSE
◍ True or False: The time it takes for a compound to flow through a metabolic
pathway is called the payoff phase..
Answer: FALSE
◍ True or False: Proteins, carbohydrates, and fats all get broken down into
acetyl-Co
A. .
Answer: TRUE
◍ A waveform that has unequal rise and fall times with one being
instantaneous is called a (blank) wave..
Answer: Sawtooth
◍ True or False: A fat is a lipid molecule that is a solid at room temperature..
Answer: TRUE
◍ A mechanic is working on a construction job, and finds the carpenter using a
powder activated tool to anchor wall track. Of the following, which
precaution should the mechanic take?.
Answer: Wear hearing protection
◍ In DNA, guanine always pairs with ________..
Answer: Cytosine
◍ If you are referring to a megohm meter, it is a test of the insulation
properties of such things as electric wiring, motor windings and high power
antenna mounts. We use a "megger" or "meg out" electrical wiring and
equipment to see if it is shorted to ground or the frame in any way. The
megger uses much higher voltages to check resistance than a normal
Volt-ohm meter. Minimum resistance is 1 Meg Ohm.

◍ A mutation in the beta-hemoglobin gene, which results in the replacement of
the amino acid glutamate in position 6 with the amino acid valine, leads to
the development of sickle cell anemia. The structures of glutamate and
valine are shown below.If the beta hemoglobin gene in a patient with
sickle-cell anemia were to be edited so that the valine in position 6 was
replaced with a different amino acid, which replacement for valine would be
expected to have the best clinical outcome, in theory, for the patient?
(Assume the valine can potentially be replaced with any amino acid other
than glutamate.).
Answer: The original amino acid in a healthy patient is glutamate, which is
negatively charged. The mutated amino acid is valine, which is non-polar.
Valine is causing sickle cell anemia. The best amino acid to replace valine
so that the patient is healthy again would be the one most like glutamate, so
any negatively charged amino acid.
◍ (1) A parallel connection. (2) A resistive element placed across the terminals
of an armature to bypass a portion of the current. (3) A flexible electrical
conductor designed to conduct current around the mechanical joint between
two conductors. (4) The resistive element (Usually of very low resistance)
used in parallel with a DC ammeter movement to bypass a calibrated portion
of the total circuit current..

◍ Which is the best way to communicate with your coworkers while you are in
the machine room and they are working in the pit?.
Answer: Two-way radio
◍ Refer to figure 1. Which of the following statements is correct?.
, Answer: Sine wave A is lagging sine wave B.
◍ Third-floor bulbs burn out why?.
Answer: Shorted resistor
◍ Water is considered a polar solvent due to attractive forces known as
hydrogen bonds. A hydrogen bond is __________..
Answer: An attractive force between molecules where partially positive
hydrogen atoms are attracted to partially negative atoms of F, O, or N.
◍ Car will not travel to second floor without a third-floor me a call and will
not go down from three without a second-floor hall, what's the problem?.
Answer: 2Fl 4/6

◍ The bridle hitch can consist of two,three, or four single hitches (fig. 3-22),
used together to form a bridle hitch for hoisting an objectA sling with two
legs used to lift a 1,000 pound object will have 500 pounds of the load on
each leg when the sling angle is 90 degrees. The load stress on each leg
increases as the angle decreases; and if the sling angle was 30 degrees lifting
the same 1,000 pound object, the load will be 1,000 pounds on each leg. Try
to keep all sling angles greater than 45 degrees; sling angles approaching 30
degrees are considered extremely hazardous and must be avoided at all cost..
