Exam 1: Life: Biological Principles and the Science of Zoology

A person goes around banging a drum each day.You ask him why.He replies,"To drive off the tigers!" You reply "But there aren't any tigers around here." He replies,"See,it works!" From a science viewpoint,this conclusion

Much of science is based on an approach known as the __________ method.

A molecular pathway in the liver that is responsible for breaking down complex molecules into simple molecules for excretion as wastes is an example of

Some ecologists study complex interactions of animals and plants in forests.Such field research produces slightly different results for different researchers.In contrast,ecology experiments performed indoors with one organism in a terrarium usually produce results that are repeatable.What is the most likely explanation?

All of the chemical energy transformations that occur within a cell constitute

The statement that the large anatomical differences that separate the major groups of animals originated through the accumulation of many small incremental changes over long periods of time illustrates Darwin's theory of

"Cryptobiosis" is a state of almost total water loss found in some roundworms,rotifers,and tardigrades and was previously considered a near cessation of metabolism.Recently,a British Museum botanist accidentally spilled fluid on a 120+year-old herbarium mount of a lichen.Fearing damage to the specimen,he immediately inspected it under the microscope and found tardigrades "waking up." This observation

A characteristic of science is that

Eventually the sun will swell to become a red giant star.This red giant will engulf the earth and then "burn out." All forms of energy will be dispersed in a final "heat death." Compared with conditions today,the total entropy of the universe then will

The theory of evolution,along with all other theories in science

Which best describes a control group in an experiment?

Which hierarchy of organization is seen in multicellular organisms such as animals,going from smallest to largest?

The second law of thermodynamics,or entropy law,means that for living organisms

The property of living organisms that involves a unique and complex molecular organization is called
