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. Correct 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.

A.Infiltration
B.Precipitation
C.Transpiration
D.Sublimation Correct 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 Correct Answer: A.Absorbing
nutrients into the body
