Genes

The group that would contain the fewest species would be: Phylum Order Family Genus

Genus

Which is not associated with reproduction in bacteria? Binary fission Conjugation Plasmids Meiosis

Meiosis

In the five-kingdom system, prokaryotes are placed in the kingdom _____. Protista Animalia Fungi Plantae Monera

Monera

In the five-kingdom system, which kingdom consists primarily of unicellular eukaryotes? Fungi Protista Plantae Animalia Monera

Protista

Viruses are not able to reproduce on their own, but can reproduce using _____.

The DNA of their hosts

How do you write the name of a species?

The first letter of the first word is capitalized and the second is all lowercased. Both words are either underlined or italicized

Why is combination drug therapy for HIV/AIDS less likely to lead to resistance than single drug therapy? In the presence of multiple drugs, the mutation rate of HIV decreases. There are fewer side effects associated with combination drug therapy, and the appearance of resistance is directly related to the severity of side effects. The likelihood of one virus spontaneously mutating to be resistant to several different drugs at the same time is extremely small. The drugs improve the immune system so that it is better able to find and remove virus particles.

The likelihood of one virus spontaneously mutating to be resistant to several different drugs at the same time is extremely small.

Which of the following statements about viruses is FALSE? Vaccines are available to prevent several diseases caused by viruses. The widespread use of antibiotics has led to resistant strains of viruses. If a virus mutates, the immune system may not recognize the virus. People can get colds and flus again because the viruses are constantly mutating.

The widespread use of antibiotics has led to resistant strains of viruses.

Phylogenetics is a type of classification of living things that takes into account ________.

Their evolutionary history

In the two-kingdom system, why were fungi classified in the kingdom Plantae? They are sedentary. They are heterotrophs. They lack cell walls. They are unicellular. They are autotrophs.

They are sedentary.

Which of the following can be found in bacteria, but not viruses? genetic material nucleic acids a cell membrane proteins

a cell membrane

Suppose you were in charge of sending an unmanned space probe to a new planet in search of life. The probe would be able to collect and test samples and make observations, but the planet is too far away for the probe to be able to bring samples back to Earth. The probe is small and would only be able to run a few tests, so you want to pick a test for evidence of life that is broad enough to incorporate all forms of life as we know it. Which one of the following tests would be the best to use in this situation? a test for the presence of cells that contain DNA a test for the presence of things that change size quickly, since it would be an indication of growth and development a test for the presence of soil suitable for growing plants a test for the presence of large organisms capable of movement

a test for the presence of cells that contain DNA

Homeostasis is a living organism's ability to pump blood through the body. ability to maintain constant internal conditions even when environmental conditions change. attempt to carry out photosynthesis even when there is no sunlight present. attempt to cool off, even when it is cold outside. ability to hibernate during cold times of the year.

ability to maintain constant internal conditions even when environmental conditions change.

Which of the following is NOT a characteristic of living things? creating energy having DNA as a genetic code exhibiting complex organization responding to stimuli being capable of reproduction

creating energy

Viruses are not alive because they are not made of cells and require a host cell for reproduction. alive because they often contain DNA. not alive because they can only carry out photosynthesis and not cellular respiration. alive because they mutate and change over time through evolution.

not alive because they are not made of cells and require a host cell for reproduction.

There is(are) _____ eukaryotic domain(s). one two three four five

one
