The process by which a gas becomes a liquid is called
A.condensation
B.freezing
C.melting
D.reduction - ANSWER- A.condensation
Condensation is the process by which a gas becomes a liquid.
Which of the following human organs is responsible for the formation of sperm cells?
A.Pancreas
B.Thyroid
C.Ovary
D.Testis - ANSWER- D.Testis
In human males, the testis is the organ in which the formation of sperm cells occurs.
Which of the following best describes the approximate length of time it takes Earth to rotate
once about its axis?
A.One hour
B.One day
,C.One month
D.One year - ANSWER- B.One day
On average, it takes 24 hours, or one day, for Earth to rotate once about its axis. The rotation of
Earth about its axis leads to the cycle of day and night.
Which THREE of the following are generally acceptable rules for laboratory activities?
A.Students should wash their hands after mixing chemicals in the laboratory.
B.Students should inform the teacher immediately of any accidents or spills in the laboratory.
C.Students should use cracked glassware only when the teacher is in the laboratory.
D.Students should read instructions thoroughly before performing laboratory procedures. -
ANSWER- A.Students should wash their hands after mixing chemicals in the laboratory.
B.Students should inform the teacher immediately of any accidents or spills in the laboratory.
D.Students should read instructions thoroughly before performing laboratory procedures
To prevent accidental ingestion or absorption of potentially harmful substances, students should
wash their hands after working with chemicals. To help maintain a safe environment, accidents
and spills in the laboratory should be reported to the teacher immediately so that a correct
response can be implemented. To safely and effectively complete laboratory procedures,
students should read instructions thoroughly before starting the procedures. Cracked glassware
is a safety hazard and should never be used.
Which of the following processes most directly involves the movement of water from the
atmosphere to Earth's surface?
A.Infiltration
B.Precipitation
C.Transpiration
D.Sublimation - ANSWER- B.Precipitation
, Precipitation is the process by which atmospheric water falls to Earth's surface in the form of
rain, hail, sleet, or snow. Because atmospheric water returns to Earth's surface primarily
through the process of precipitation, it is an important part of the water cycle. Infiltration is the
process by which water on Earth's surface enters the subsurface soil and rock. Transpiration is
the process by which water evaporates from plant leaves and enters the atmosphere.
Sublimation is the process by which a substance transitions directly from the solid phase to the
gas phase without going through the liquid phase.
Which of the following is an important function of the digestive system?
A.Absorbing nutrients into the body
B.Transporting signals to and from different parts of the body
C.Providing structural support for the body
D.Protecting the body from ultraviolet radiation - ANSWER- A.Absorbing nutrients into the
body
The digestive system includes organs that break down food into small molecules, which are then
absorbed into the body. The primary location of absorption is the small intestine.
As a rock begins tumbling down a hillside, most of its gravitational potential energy is converted
into
A.kinetic energy
B.thermal energy
C.chemical energy
D.nuclear energy - ANSWER- A.kinetic energy
Kinetic energy is the energy of motion. As the rock begins moving down the hillside under the
influence of gravity, most of the rock's gravitational potential energy is converted into kinetic
energy.
