When examining a gram stain slide, gram negative bacteria will appear:

What protective measures can a laboratory worker take when working with actively growing cultures to ensure that they do not become infected?

Bacterial media with added supplements that support the growth of fastidious organisms is called:

Factors that determine the pathogenicity and increase the virulence of organisms include all the following, except

Which of these bacteria cannot grow in the presence of oxygen?

An eye culture from a patient with conjunctivitis grew a gram negative rod.  The colonies were large and spreading, beta hemolytic.  What test would most likely need to be performed?

The following code segment is used for both parts 5 and 6. 1| if subscription == “Premium” and hd_available:2|     print(“You’ve been upgraded to HD!”)3| elif (subscription == “Premium” or subscription == “Standard”) and sd_available:4|     print(“You’ve been upgraded to SD!”)5| else:6|     print(“You’re on the basic plan.”)   Which of the following values for subscription, hd_available, and sd_available would result in “You’ve been upgraded to HD!” being printed?

1| try: 2| some_function() 3| except Exception as the_error: 4| print(the_error) 5| [fill in this blank]6| print(“Code complete!”) The code segment above attempts to run a function called some_function, but if it fails, it tries to print the error that occurred. Only if some_function() ran without errors is “Code complete!” printed at the end. Which of the following lines would complete this code so that it behaves as intended?

1| [fill in this blank] 2| while i < 10: 3| i += 4 4| print(i)   The code segment above defines a while loop. In the blank below, enter text that could replace [fill in the blank] so that the code prints as follows: -315913 Do not use spaces in your answer. (The autograder may accept some combinations of spaces, but not all, so to be safe, just avoid using them.)

A function check_capacity determines whether a more items can be added to a container or if it is full. It takes two positional parameters: current_items and max_items, which are both numbers and are defined in this order. It also has an keyword parameter allow_overflow, which defaults to the boolean False. If allow_overflow = False, the function returns the boolean for if the current_items are less than or equal to max_items. If allow_overflow = True, it allows the container to exceed the maximum, thus always returning True. Enter the result of each of the following function calls. If an error would arise, enter the word Error. check_capacity(9, 4) [blank1] check_capacity(7, 7, allow_overflow = False) [blank2] check_capacity(7, 6, True) [blank3]
