Technology is the __________________________.
Application of scientific knowledge for a practical purpose
If a new anti-cancer drug is found to be effective in initial tests with mice, what might researchers
conclude?
The drug os effective in the mouse model, it must still be tested in humans
Which statement regarding science technology is false?
Science technology is a basis for all ethical or moral decisions
Which of the following is a potential consequence if people stop using technology in the agriculture
industry?
There could be a significant decrease in the amount of food produced
The three major domains of life are
Arachaea, bacteria, eukaryotes
Which of the following is one of the domains of life?
Eukarya
Corn belongs to the kingdom
,Plantae
You have discovered a previously unknown organism. It is multicellular, with a filamentous form, and
absorbs food from its environment. Upon microscopic examination, you see that the cells have nuclei.
How would you classify this organism?
Kingdom fungi
Which classification category includes the most species?
Kingdom
Humans belong to the kingdom of
Animalia
Which sequence correctly lists the different levels of biological organization, from the smallest and
simplest to the largest and most complex?
Cells-tissues-organs-organ systems-organisms
Which level of biological organization is composed of several tissues?
Organ
Which statement about an ecosystem is incorrect?
There is a community of organisms but no non-living components
All the organisms of various species living within a given area constitute a(n)
Community
When comparing energy and chemicals in an ecosystem,
Chemicals cycle over and over again, but energy flows through once
Which of the following is of least importance when concerning the preservation of ecosystems?
Preservation of ecosystems allows humans to exploit as many resources as possible
An ecosystem generally requires solar energy, nutrients, decomposers, consumers and ____
Producers
As the human population size increases,
Biodiversity is adversely affected as humas have destructive effects on ecosystems
Ever since the antibiotic drug penicillin was discovered in 1928, the incidence of resistant bacteria has
steadily increased as a direct result of
Natural selection
A community of organisms along with their physical environment constitutes a(n)
, Ecosystem
The term "biodiversity" refers to
The toatal number of species, variation of species and the ecosystems in which they live
Which statement concerning reproduction is false?
The offspring of multicellular organisms tend to be identical to the parent.
What type of reaction is necessary to produce a dipeptide from individual amino acids?
dehydration reaction
Cholesterol is a component of cell membranes and is an example of which type of lipid?
steroids
We have an expert-written solution to this problem!
Which of the following is not a function of ATP within the cell?
All of the answer choices are functions of ATP within the cell.
The water strider is an insect that skates across the water without sinking. The tips of its feet must be
coated with molecules that are
hydrophobic
Which of these combinations would be found in a nucleotide?
base, sugar, phosphate
The backbone of a nucleic acid strand is composed of
alternating pentose sugars and phosphate groups.
Lactic acid can be taken to the liver via the bloodstream, and the liver can convert it to
glucose
In the search to discover the agents that cause mad cow disease, scrapie in sheep, and CJD and kuru in
humans, diseased brain tissues were passed through a fine filter to remove bacteria. The filtrate was still
infectious, indicating that something smaller than bacteria, either viruses or organic molecules, must be
the causative agent. If a virus was responsible for these brain diseases, then the infectious agent would
contain either RNA or DNA. Other possibilities were that the agent was a carbohydrate, fat, or protein.
Tissue filtrates were treated with agents that destroyed just one of these chemicals and then injected
into a healthy animal, with the results as follows. What is the infectious agent?
•Amylase digests carbohydrates; tissue filtrate still infects healthy test animal.
