Prokaryotes reproduce asexually by a process that begins with the
replication of a prokaryote’s DNA. The cell membrane then pinches in two to
form two daughter cells. What is the term describing this process? Meiosis,
conjugation, recombination, or binary fission

Meiosis
2
Some prokaryotes and eukaryotes have whip-like projections that
help propel the cell through liquid. What is the name of this whiplike projection? A cilium, a villus, a pilus, or a flagellum
2

flagellum
3
Which of the following organelles contains most of the cell’s
DNA? Mitochondria, lysosome, nucleus, or ribosome

nucleus

Plant and animal cells are both eukaryotic, and thus they are similar in many ways.
However, plant cells have some structures that are not present in animal cells.
Which of the following structures are not found in animal cells?
A.
chloroplasts, large vacuole, and endoplasmic reticulum
B.
C.
D.
Cell wall, golgi complex, and ribosomes
Cell wall, chloroplasts, and a large vacuole
Chloroplasts, an endoplasmic reticulum and lysosomes

In living organisms, DNA consists of two complementary strands wound
together in a specific structure called a? Beta sheet, double helix, spiral
helix, or triple bond

Double helix

Charles Darwin observed the resemblance between
organisms on the Galapagos Islands and those on the
nearest coast. He hypothesized that the island organisms
had evolved from the coastal organisms. What mechanism
did Darwin propose caused evolution, punctuated
equilibrium, genetic drift, natural selection, or gradualism

Natural selection

In 1986, hundreds of islands were created out of hilltops when Venezuela was
flooded because of a closed dam. On all of these new islands, the top
predators in the food chain, such as jaguars and eagles died out. What most
likely happened to the herbivores and smaller carnivores in those local food
chains after the predators disappeared?
A.
Their populations decreased
B.
C.
Their diets changed
They all developed new adaptations of defense.
D.
Their populations increased

All plants and animals need energy in order to survive. The energy
transfer system above shows how energy gets transferred among living
things. If all of the worms were removed from the region, which species
would have more energy available to it? Wasps, spiders, frogs, or
grasshoppers

Grashoppers

Through the process of photosynthesis, algae convert
sunlight into sugars. If you had to redraw this food chain to
show one more level before the algae, what would be the
best thing to draw? Sugar, plants, water, or the Sun
