Evaluate 2/x+(5/y/x/4)+6/7 when x=3 and y=6 - ACCURATE
ANSWERS✔✔ 14/15
what makes up a pyrimadine? - ACCURATE ANSWERS✔✔ a nitrogen
at the 1 and 5 position in the structure.
If one parent has the genotype AABb and the other has the genotype
AaBB, what is the chance of a child being homozygous recessive for
both traits? - ACCURATE ANSWERS✔✔ 0%
,If one kilometer is 62% of a mile, what is 21/5miles in kilometers and
meters, to the nearest meter? - ACCURATE ANSWERS✔✔ 3
kilometers, 548 meters
Which germ layer of the human embryo gives rise to the lining of the
esophagus? - ACCURATE ANSWERS✔✔ Endoderm
The half-life of the radioactive element Weissonium is 6 days. How
much of an original sample of 30 grams will have decayed after 24
days? - ACCURATE ANSWERS✔✔ 28 1/8g
In the pyramid of energy, the greatest amount of stored chemical bond
energy is found in - ACCURATE ANSWERS✔✔ Primary producers
x + 1⁄y - y + 1⁄x ? - ACCURATE ANSWERS✔✔ (x+y+1)(x-y)/xy
Which of the following is most nearly equal to 479.93⁄.00598? -
ACCURATE ANSWERS✔✔ 80,000
Which of the following is the weakest base in aqueous solution? -
ACCURATE ANSWERS✔✔ HSO4-
At 760 torr, solution X boils at 100.26 °C and solution Y boils at 101.04
°C. If both aqueous solutions contain the same nonvolatile solute, which
of the following statements must be true? - ACCURATE
,ANSWERS✔✔ The vapor pressure of solution X is higher than that of
solution Y at 25 °C.
Which of the follow is equivalent to 6!⁄4! (This is a factorial question). -
ACCURATE ANSWERS✔✔ 5!/4
Which of the following occurs during synapsis? - ACCURATE
ANSWERS✔✔ Homologous chromosomes come together and
intertwine
Justin requires 5 hours to paint a certain room. Suzanne requires 3 hours
to paint the same room. If Justin and Suzanne work together, how long
will it take them to paint 1⁄3 of the room? - ACCURATE
ANSWERS✔✔ This question involves two steps: [Product of individual
times/ sum of individual times]
straightforward use of the work formula and then a manipulation of the
result. If the two people, working independently, need five hours and
three hours to paint the room, then, working together, they'd need hours
to complete the entire room. But since we're concerned with the time
they'd need to complete only of the room, we can say that they'd need
of ,.
Which of the following statements is true of ethene? - ACCURATE
ANSWERS✔✔ Both carbon atoms are sp2 hybridized and the molecule
is planar.
Conduction - ACCURATE ANSWERS✔✔ direct transfer of energy
from molecule to molecule via direct molecular collsions
, What are the best and worst conductors? - ACCURATE ANSWERS✔✔
Worst= gases
Best= metals
Convection - ACCURATE ANSWERS✔✔ heat transfer by physical
motion; only takes place in fluids and gases. Heat energy is transferred
AWAY from the source.
Radiation - ACCURATE ANSWERS✔✔ transfer of energy by
electromagnetic waves. Radiation can travel through a hard vacuum.
Ex: energy from sun
specific heat - ACCURATE ANSWERS✔✔ c, amount of heat energy
needed to raise the temperature of 1kg by on degree K.
What is the specific heat of water? - ACCURATE ANSWERS✔✔ 4186
J/kg*K
Heat transfer formula - ACCURATE ANSWERS✔✔ Q=mc(Tf-Ti)
Heat of transformation from solid to liquid - ACCURATE
ANSWERS✔✔ heat of fusion
Heat of transformation from liquid to gas - ACCURATE ANSWERS✔✔
heat of vaporization
