Exam 1: Evolution, the Themes of Biology, and Scientific Inquiry

The evolution of one species into two or more species as a result of different populations becoming reproductively isolated from each other is best termed as ________.

Systems biology is mainly an attempt to

Characters are transmitted from parents to offspring. ________ are the units of inheritance.

Agrobacterium infects plants and causes them to form tumors. You are asked to determine how long a plant must be exposed to these bacteria to become infected. Which of the following experiments will provide the best data to address that question?

In presenting data that result from an experiment, a group of students show that most of their measurements fall on a straight diagonal line on their graph. However, two of their data points are "outliers" and fall far to one side of the expected relationship. What should they do?

As letters are to English language, ________ is/are to genetic information.

A controlled experiment ________.

The best experimental design ________.

Which of the following best demonstrates the unity among all organisms?

Which of the following is true of natural selection?

Which of the following statements is true regarding the complexity of biological systems?

Which of the following is an example of qualitative data?

Which of these is an example of inductive reasoning?

Agrobacterium infects plants and causes them to form tumors. You determine that tumor formation requires a large amount of the plant's energy for tissue formation. How might this change the number of offspring a plant produces, and what is the most likely explanation for this change?

The process by which the information in a gene directs the synthesis of a protein is called ________.

Use the following information when answering the following question. In 1668, Francesco Redi performed a series of experiments on spontaneous generation. He began by putting similar pieces of meat into eight identical jars. Four jars were left open to the air, and four were sealed. He then did the same experiment with one variation: Instead of sealing four of the jars completely, he covered them with gauze (the gauze excluded the flies while allowing the meat to be exposed to air). In both experiments, he monitored the jars and recorded whether or not maggots (young flies) appeared in the meat. In both experiments, flies appeared in all of the open jars and only in the open jars. Which one of the following statements is correct?

When your body temperature rises on a hot day, the neural and hormonal mechanisms activate sweating. Evaporation of sweat leads to cooling of the body surface. This is an example of ________.

Use the following figure to answer the question. The phylogenetic tree ________.

Cotton-topped tamarins are small primates with tufts of long white hair on their heads. While studying these creatures, you notice that males with longer hair get more opportunities to mate and father more offspring. To test the hypothesis that having longer hair is adaptive in these males, you should ________.

Which of the following types of cells utilize deoxyribonucleic acid (DNA) as their genetic material but do not have their DNA encased within a nuclear envelope?
