Exam 1: The Science of Biology

Biological order can be seen in a __________ organization,from the level of highly structured organic molecules in the cells to the highest level of populations and communities in biomes and biosphere.

The best explanation for the high number of spiders in plot 4 is

Why was the determination of the actual sequence of the human genome considered to be descriptive science?

Plants are raised under artificial lights turned off and on by an electric clock.Some are given long periods of light,others short periods.

A medical scientist is designing an experiment to test the results of a new drug that she hypothesizes will greatly reduce and possibly eliminate the side effects of a new cancer treatment.If this experiment is to be set up correctly,she must

The function of Pax6 in eye development can be viewed as an example of

A suggested explanation that might be true and is subject to testing by further observations is a(n)

You have been assigned to analyze some extraterrestrial material recently collected from Mars.After examining a sample using a microscope you jump up excitedly and shout to your colleagues that you have confirmed the existence of life on Mars.One of your colleagues takes a look at your sample and remarks that all he sees is a single-celled blob with little internal structure.Assuming that life on Mars can be classified into similar domains and kingdoms as Earth,to which domain does your blob belong?

The fact that your vehicle did not start when you tried to leave for work is best described as

The scientific method involves making careful observations,asking questions,formulating hypotheses,collecting data,testing,and making conclusions about the collected data.Of the following statements about toxic wastes,select the choice that science cannot address.

You have been assigned to address a problem of overpopulation of species X in a nearby county.One of the members of your team suggests introducing species Y,which is a natural predator of species X,but not normally found in the area.After some discussion,you go ahead and introduce species Y.What aspects of the hierarchical organization may be affected within a period of a several years?

Hypotheses which are consistent with the results of experimental testing are

The scientific process involves

A key contribution to Darwin's thinking was the concept of limits put on the geometric growth of populations by nature,originally proposed by

Modern pieces of evidence that corroborate Darwin's theory of evolution include all of the following except

The cell theory is one of the foundations of biology.Which of the following statements is not consistent with this theory?

Birth and death rates of populations are not constant with time.If the birth rate exceeds the death rate,then the population increases with time.If the death rate exceeds the birth rate,the population decreases with time.Death rates can change unexpectedly due to all of the following conditions except

If you were to design a long-term research study to determine why there are no human births in Lapland during the months of August,September,and October,you would need to also examine a comparison population of humans in which births took place every month.The primary reason for including a comparison population within the design of this experiment would be to

Darwin's book in which he described his views on evolution is

Which of the following characteristics are not necessary to being "alive"?
