ATI TEAS VERSION 7 PRACTICE TEST –
SCIENCE QUESTIONS WITH CORRECT
ANSWERS
A researcher notices a positive correlation between the height of a plant and nutrient
concentration over time. Based on this observation, what conclusion does he reach? -
Answer-When the amount of nutrients available to the plant increases, its height also
increases.
Which statement best represents Mendel's experiments with garden peas? - Answer-
Mendel collaborated with others interested in genetics to develop heredity guidelines we
still use today.
Which of the following is a component of a chromosome? - Answer-centromere
What solution has a pH of 7? - Answer-pure water
Which is classified as a type of acid-based reaction that produces a salt? - Answer-
Neutralization
Which of the following determines the strength of an acidic solution? - Answer-
Measured pH value less than 7
What type of bond forms between nitrogen and oxygen, and why? - Answer-covalent,
because electrons are shared
Which of the following atoms is a cation? - Answer-82 protons, 125 neutrons, 78
electrons
Because it has more protons than electrons, this atom has a positive charge and can be
classified as a cation.
A spoonful of sugar is added to a hot cup of tea. All the sugar dissolves. How can the
resulting solution be described? - Answer-Unsaturated and homogeneous
In the following single-replacement reaction, __________ replaces __________.
Cl2+2NaI -> 2NaCl+I2 - Answer-Chlorine, Iodine
_________ is dependent not only on the temperature, but also on the amount of
substance available. - Answer-evaporation
During which of the following phase changes will the cohesion between the particles in
a substance decrease? - Answer-vaporization
