Biology Regents Review 10th grade
A human cell that contains all of the information necessary for the growth and development of a complete organism is
a zygote
Recently, researchers from Stanford University have changed mouse skin cells into mouse nerve cells. This was accomplished by inserting genes that control the synthesis of certain proteins into the skin cells. This type of research is often successful in advancing knowledge regarding the functioning of human cells because
cells present in humans often function in similar ways to cells present in other organisms
In humans, the maintenance of a stable internal temperature is a direct result of
detection of and reaction to stimuli in the environment
When would exposure to a potentially harmful substance be most likely to damage many organs in a developing embryo?
during the early stages of pregnancy
An energy-rich organic compound needed by organisms is
glucose
A male frigatebird displays to the female by inflating its large red throat sac, throwing its head back, vibrating its wings, and producing a "drumming" sound with its throat sac. For the frigatebird, this behavior has most likely resulted in
greater reproductive success
Plant species X lives in a hot, dry environment. Slowly, over hundreds of years, the climate becomes wetter. Fungi attack species X and cause the population of species X to decrease. However, plant species X could survive if the plants
have a few members of the population that are fungus resistant
Which statement best expresses a basics scientific assumption?
if a conclusion is valid, similar investigations by other scientists should result in the same conclusion
An organ, such as a kidney, used for transplant needs to be tested for compatibility with the person who is to receive the organ. If this is not done, the
immune system might attack the donated organ
Fossils provide evidence that
many species of organisms that lived long ago are now extinct
For a human zygote to become an embryo, it must undergo
mitotic divisions
In August 2010, the Asian clam was discovered in Lake George. It is not native to that area. A single clam can reproduce and release hundreds of offspring in a day. Fish and crayfish eat the clams but cannot keep pace with the rate at which the clams reproduce. The introduction of the Asian clam into Luke George is
negative, because it competes with native clam species and reduces stability
SCIDS (Severe Combined Immunodeficiency Syndrome) is a disorder where a genetic mutation inhibits the production and functioning of T-cells. T-cells are special types of white blood cells that play a role in the body's immune response. A possible symptom of SCIDS would be an increase in the
number of infections by pathogens
Which sequence represents structures organized from most complex and least complex?
oak tree - leaf - guard cell - chloroplast
The overuse of chemical fertilizers has resulted in the growth of some lawn ecosystem to
recycle nutrients
Before a cell divides, an exact copy of each chromosome is made by the process of
replication
The humans actions that have been made possible in recent times are: Doctors are able to diagnose and treat some fetal problems prior to the birth of a child Cloning can produce large numbers of plants that are resistant to drought Male insects can be sterilized with radiation to prevent them from mating successfully
reproductive technology has medical, agricultural, and ecological applications
A student received a flu shot in the fall. During the flu season, the student caught a cold. The most likely reason the vaccine he received did not prevent could was that
the vaccine he received contained only flu virus antigens
A researcher concludes from a 10-year study that the biodiversity of an ecosystem had increased. Which set of observations represents evidence for this claim?
there were mote niches and greater stability in the ecosystem
