NLN PAX SCIENCE 2026 EXAMINERS SET
QUESTIONS AND ANSWERS SURE A+
✔✔A recently discovered species has these characteristics: amniotic eggs, a four-
chambered heart, and lightweight, honeycombed bones. Which of these ADDITIONAL
characteristics is likely to be present? - ✔✔Feathers for flying
✔✔Which part of the human central nervous system controls voluntary movements? -
✔✔Cerebrum
✔✔Which of these hydrocarbons is a member of the benzene family? - ✔✔Toluene
✔✔The process of nuclear cell division in the cell reproduction of plants differs from
mammals. A major difference is that - ✔✔cell plates are synthesized
✔✔Which of these quantities is a vector quantity? - ✔✔Energy
✔✔A quantity that has both magnitude and direction is called a(n) - ✔✔vector
✔✔According to the Ideal Gas Equation (PV=nRT), if the temperature and amount of
gas are kept constant, what will be the effect of an increase in pressure on the volume
of a gas? - ✔✔As the pressure increases, the volume decreases.
, ✔✔Cicero and Wozniak probably decided to restrict their study to male offspring of
alcoholic male rats because they wanted to - ✔✔compare results with prior findings
from human studies
✔✔In a study on the effect of cocaine on the brains of rats, two groups of animals were
selected. Each day, Group A was injected with the drug dissolved in water, whereas
Group B was injected with water alone. In such a study Group B is included as - ✔✔a
control group
✔✔In classical physics, light is viewed as part of the electromagnetic spectrum,
traveling in the form of transverse waves. Quantum physics proposes that light is
composed of quanta called - ✔✔photons
✔✔Reducing the use of aeresol cans has contributed to the decrease of - ✔✔the
destruction of the ozone layer
✔✔The *Watt* is a unit of - ✔✔power
✔✔The normal boiling temperature for water is 100° when measured on which of these
scales? - ✔✔Celcius
✔✔The second law of thermodynamics states that with every spontaneous process, the
entropy of the universe - ✔✔Increases
✔✔All of these groups of land plants produce seeds EXCEPT - ✔✔mosses
✔✔When blood is filtered in the kidney and urine is produced, red blood cells and
plasma proteins do not pass through the blood capillaries. This occurs because -
✔✔large molecules such as blood and plasma proteins do not fit through the permeable
membrane, so they cannot enter the tubules in the kidney.
✔✔The extension of a neuron that carries the impulse to another cell is called - ✔✔an
axon
✔✔Which of these structures of the male reproductive system carries sperm cells from
the testes to the lower part of the abdomen? - ✔✔Vas deferens
✔✔Which of these pH values represents the most basic solution? - ✔✔14
0-6 = acidic
7= netural
8-14 = basic
