Your teacher has given each student the name of a key figure in the history of psychology. The assignment is to describe at least one significant contribution made by this person. If your historical figure is Hermann Ebbinghaus, what contribution might you describe to the class?

Which of the following is NOT an example of a resource?

Which of the following species belong to the same guild?

What accounts for the pyramid shape of the diagram that represents energy in trophic groups in an ecosystem?

Tight coevolution between flower and pollinator morphology (only one species of pollinator can pollinate one species of plant) will likely occur when:

In the mutualism between corals and zooxanthellae (microscopic algae), the coral dies if the algae is expelled, a phenomenon known as coral bleaching. Different coral species can be colonized by multiple species of algae. From the perspective of the coral, the type of mutualism is:

A study hypothesized that the amount of scales and mucus of different species of fish eaten by cleaner fish would depend on the abundance of parasites in their oral cavities. Based on their results apply a t test and answer the following questions   Low abundance of parasites High abundance of parasites Average mucus and scales consumed (%) 23 18 Variance (s2) 14 12 Number of fish sampled 21 21 What is the T value calculated?

Answer the following short coding questions. Do NOT write functions and do NOT hardcode.  Given a text file called marvel.txt with some consecutively duplicate lines, copy over the duplicate lines to a new text file with same name with _copies.txt appended.   Example:   marvel.txt: 1| I ron-man is in Avengers.  2| Wolverine is in X-men.  3| Quicksilver is in Avengers & X-men.  4| Quicksilver is in Avengers & X-men.  5| Vision is in Avengers.  6| Wanda is in Avengers & X-men.  7| Wanda is in Avengers & X-men.  8| Magneto is in X-men.  The resulting file, marvel_copies.txt:  1| Quicksilver is in Avengers & X-men.  2| Wanda is in Avengers & X-men.     Notes:   The duplicate lines should be written in the new file in the same order that they appear in the original file.  The output file can have a newline character at the end.  Words are defined as something separated by a space. For example, “iron-man” counts as one word, not two, since there is no space between “iron” and “man”.   Answer this question by typing your code in the space provided below.

The following function is defined in the current directory. Consider the function and answer the questions below. Answer the short-answer questions in the space provided below. 1 function  final = superhero(heroes)  2     [current, potential] = strtok(heroes, ‘ ‘);  3     while ~isempty(current)  4         if mod(length(current), 2) == 1  5             final = current;  6         end  7         [current, potential] = strtok(potential, ‘ ‘);  8     end  9 end    You run the following lines of code in your Command Window:   >> heroes = ‘max tuanh nikita sam matt sunny bob’  >> output = superhero(heroes)   Please indicate each answer by preceding it with the same letter that precedes the question.  What is the value and class of the variable output after the code in the Command Window runs?  How many times will the while loop on line 3 run after the code in the Command Window are run? What inputs would cause this code to error from an “output variable not defined…” error? You may give an example or clearly describe what format the example input would have.
