BIOLOGY EOC PRACTICE EXAM Q&A
What is the process of moving molecules across the membrane and DOES require
energy - ANSWER-Active Transport
What is the process that DOES NOT require energy - ANSWER-Passive Transport
Know the Molecule of DNA - ANSWER-
If a mutation occurs in a somatic cell, what cell will be affected? - ANSWER-Only
daughter cells
If a mutation occurs in a gamete, what cells will be affected? - ANSWER-All cells
What are 2 other forms of asexual reproduction? - ANSWER-1. Binary Fission
2. Fragmentation
Whats a tetrad? - ANSWER-Pairing of homologous chromosomes
What is the Law of Segregation? - ANSWER-Separation of genes
What is Hapliod - ANSWER-A cell with half chromosomes
What is asexual reproduction? - ANSWER-The organism inheruts all of its
chromosomes from a single parent; it is identical to parents
What is sexual reproduction? - ANSWER-The organism inherits its chromosomes
from two cells. It is faster
If half of the existing habitat is cleared for a new home development, the diversity of
species in the area will increase/decrease - ANSWER-Decrease
What is the 10% rule - ANSWER-Only pass on approximately 10% of energy to the
next trophic level 90% of energy is lost as heat
The gopher snake uses its glottis to produce a hiss that sounds similar to a
rattlesnake's rattle. What is the most likely reason a gopher snake would do this? -
ANSWER-to confuse predators
A population of salamanders that line in a river require clear, fresh water to survive.
A flood causes tons of sediments to be suspended in the river. Which of these most
likely will happen to the salamander population? - ANSWER-the salamanders will
decrease in number because of the water quality
The diagram shows a food web, a reduction in which of these species would lead to
a decrease in all the other populations in the web? - ANSWER-Grass/Trees
, Which of these best explains the difference between the way animals and plants
exchange gases with their environments? - ANSWER-Animals use only respiration;
while plants use both photosynthesis and respiration
What is the main function of a selectively permeable cell membrane? - ANSWER-
regulates what enters and leaves the cell
The Papaya mealybug is a pest that poses a threat to many tropical plants. Which
fate of the mealybug would result from the inability of the species to reproduce? -
ANSWER-the species would become extinct
In a certain insect, round wings (H) are dominant to pointed wings (h). What cross
will produce the greatest number of genotypic and phenotypic variations? -
ANSWER-Hh x Hh
Which of these best describes mutualism? - ANSWER-a relationship between two
species where both species benefit
Which of these would be least likely to diffuse across the phospholipid bilayer of a
cell membrane? - ANSWER-sodium (Na) ions
How would a drop in temperature most likely affect the processes of cellular
respiration and photosynthesis? - ANSWER-The rates of both cellular respiration
and photosynthesis would decrease
Which abiotic factor limits the altitude at which plants can grow? - ANSWER-the
temperatures of the area
How many daughter cells are formed in meiosis? - ANSWER-four
Which of these shows the steps by which proteins are coded and synthesized? -
ANSWER-DNA - RNA - protein
Two gametes containing 20 chromosomes fuse during fertilization. How many
chromosomes will the zygote cell contain? - ANSWER-Forty
A molecule can easily pass through the selectively permeable membrane of an
animal cell. Which of these most likely describes the molecule? - ANSWER-very
small and not charged
Which of these directly allows blood cells to transport oxygen to various parts of the
body? - ANSWER-Hemoglobin
One species of Galapagos finches, the cactus finch, eats insects off cactus plants. A
disease kills off most of the cacti in the Galapagos Islands. Which of these most
likely would happen to the carrying capacity of the island? - ANSWER-It would
decrease considerably since the finches are specifically adapted to their niche.
