General Science Version 1

A scientist isolates a human DNA repair gene and inserts it into a plasmid. The plasmid is inserted into a bacterial cell, so more plasmid can be produced. After isolating the plasmid from the bacterial cells, the scientist inserts the plasmid DNA into a human tissue culture cell using a virus. Which of the following statements regarding VECTORS is TRUE?

• Four different vectors were used in this experiment.

• Two different vectors were used in this experiment.

• This experiment did not involve the use of vectors.

• Three different vectors were used in this experiment.

A day when the earth's axis is either closest or farthest from the sun is known as a

• equinox

• solstice

• rotation

• lunar month

On the summer solstice, we have our longest day of the year because the earth's axis is closest to the sun giving us more sunlight hours. On the winter solstice, we have our shortest day of the year because the earth's axis is farthest from the sun.

A car driving down a flat road has most of its energy in kinetic energy. When the car stops, where does the kinetic energy go?

• It is destroyed and evaporates into the air.

• It is converted to light energy.

• It is converted to gravitational potential energy.

• It is converted to heat and sound as dissipated energy.

How does the fossil record support evolution?

• It creates a timeline of evolutionary events from oldest to youngest

• It shows that island species are related to other island species

• It layers fossils from youngest at the bottom to oldest at the top

• It perfectly preserves organisms from each time period

• It preserves each change a species experiences as it evolves
