Answers Verified 100% Correct
Snowflakes *form from tiny water droplets,* following a specific
process of chemical
bonding as they freeze, which results in a six-
sided figure.
A. No change
B. form, from tiny, water droplets,
C. form from tiny, water, droplets
D. form, from tiny water droplets - ANSWER A
The rare "triangular" snowflake, *similarly,* confounded scientists for
years because it
apparently defied the basic laws of
chemistry.
F. No change
G. for example,
H. additionally,
J. however, - ANSWER J
The seemingly triangular shape of those snowflakes suggests *that
forming* through a
different process of chemical
bonding.
A. No change
,B. the manner in which formation
C. which had formed
D. that they form - ANSWER D
By re-creating snowflake formation, *a discovery has revealed to
scientists Kenneth
Libbrecht and Hannah Arnold the cause of this apparent
variation.*
F. No change
G. the discovery of the cause of this apparent variation has been made
by scientists
Kenneth Libbrecht and Hannah Arnold
H. scientists Kenneth Libbrecht and Hannah Arnold have discovered
the cause of this apparent variation.
J. the cause of this apparent variation has been discovered by scientists
Kenneth Libbrecht and Hannah Arnold - ANSWER H
Snowflakes begin to form when water in the atmosphere *freezes it
causes* the water
molecules to bond into a hexagonal
shape.
A. No change
B. freezes, causing
C. freezes, it causes
D. freezes, this causes - ANSWER B
,During the flake's descent from Earth's upper atmosphere, other water
vapor molecules
*bumps* into the hexagonal
structure.
F. No change
G. has bumped
H. bumped
J. bump - ANSWER J
*Bypassing the liquid water phase*, those molecules condense directly
onto the established hexagonal pattern. As a result, the flake grows
outward into bigger and more complex hexagonal arrangements
surrounding the original hexagonal shape at the center of the flake.
If the writer were to delete the * * portion (adjusting the capitalization
as needed), the
sentence could primarily
lose:
A. an explanation of the process water molecules undergo to change
from liquid to vapor to solid.
B. a detail that mentions a step some water molecules skip in changing
from vapor to solid.
C. a visual description of what water vapor molecules look like.
D. an explanation of how molecules react to various air temperatures. -
ANSWER B
, In 2009, Libbrecht and Arnold's experiments revealed that triangular
snowflakes begin
with the same process of chemical bonding and *forms* a
hexagonal shape.
F. No change
G. were they to form
H. if they formed
J. form - ANSWER J
The triangular shape is an illusion resulting from one significant
addition to the
*process*
dust.
A. No
change B.
process is
C. process:
D. process; - ANSWER C
Triangular snowflakes begin to form when a tiny dust particle or other
such impurity collides with the flake as it falls, thereby pushing one
edge upward. The greater *the pressure from the wind,* causes bonds
to form *quick* at this edge than in the rest of the snowflake.
F. No change
G. pressure from the wind, which
H. the pressure, as the wind
