NLN PAX Practice Tests Fall 2023
An organism with chloroplasts in its cells is probably....
a- a heterotroph
b- an autotroph
c- a herbivore
d- a primary consumer
(S1, p218-228) Correct answer- b- an autotroph
organisms that have chloroplasts in their cells carry on photosynthesis and are therefore
autotrophs
- autotrophs make their own food
(Q1)
What property of water allows someone to fill a glass slightly above the rim with out the
water flowing over?
a- specific gravity
b- capillarity
c- opacity
d- surface tension
(S1, p218-228) Correct answer- d- surface tension
(Q2)
The spaces b/w neurons are called.....
a- synapses
b- dendrites
c- inter-neurons
d- cell gaps
(S1, p218-228) Correct answer- a- synapses
(Q3)
As light passes obliquely from air to water, it is bent. This bending is called.....
a- diffraction
b- reflection
c- refraction
d- dispersion
(S1, p218-228) Correct answer- c- refraction
(Q7)
Which of the following organelles is NOT involved in protein synthesis?
, a- ribosome
b- mitochondrion
c- rough ER
d- nucleus
(S1, p218-228) Correct answer- d- nucleus
(Q8)
NOTE:
- the nucleus contains DNA
- the ribosomes, located on the rough er, are the site for protein synthesis
- the mitochondrion are the sites of cellular respiration
Which group of organisms helps prevent the accumulation of organic wastes in nature?
a- rabbits
b- mosses
c- bacteria
d- ferns
(S1, p218-228) Correct answer- c- bacteria
(Q15)
Bacteria comprise the decomposer portion of the food chain. They are responsible for
recycling organic material into inorganic material that plants can use to undergo
photosynthesis
As the eardrum is made to vibrate more rapidly, the sound is perceived as.....
a- louder in intensity
b- softer in intensity
c- higher in pitch
d- lower in pitch
(S1, p218-228) Correct answer- c- higher in pitch
(Q16)
the more rapid the vibration is, the higher the pitch is
A human egg will develop into a female if it is fertilized by a sperm containing.....
a- an x chromosome
b- a y chromosome
c- an xy chromosome
d- an xxy chromosome
(S1, p218-228) Correct answer- a- an x chromosome
(Q20)
