It took very long for scientists to find out that infections were caused by bacteria because they are microscopic organisms and the knowledge of microbes was still non-existent. This changed with the invention of the Microscope by Hans and  Zacharias Janssen in 1590.

<h3>The discovery of Microbes</h3>

Although Hans and Zacharias invented the microscope, microbes were not discovered until Robert Hooke and Antoni Van Leeuwenhoek created it as a scientific instrument.

Antoni Van Leeuwenhoek is credited for having discovered bacteria in 1676.

Which of these is the free morpheme of the word unhelpful
blagie [28]
  There are two main kinds of morpheme: bound and unbound. A free morpheme is also called unbound morpheme. It’s composed of words that can stand alone. These words can appear as lexeme. A bound morpheme on the other hand is a mere grammatical unit which doesn’t occur by itself. It always needs to be attached to a free morpheme.  
<span>
Thus, the free morpheme here is “help”.   It can stand along and serves as a lexeme. The affixes “un” and “ful” on the other hand are examples of bound morpheme which are naturally dependent. </span>

I’m the “first seven years” by Bernard Malamud, how is the climax of the story also and epiphany
s2008m [1.1K]

At the beginning of the story, Feld, the shoemaker, yearned for his daughter to marry a man with a promising and wealthy future, so she could live a happy life. Later in the story, after two dates between both Miriam (her daughter) and Max (a young student), Feld was told by Miriam that she was not interested in Max, given her materialistic nature. Feld did not understand her reason at the time, but didn't give it much thought.

Near the end of the story, Feld realized Sobel's (his assistant) feelings for her daughter, but wasn't very comprehensive about them, given Sobel's old age and poor living conditions.

While watching Sobel's scorn after having his desires represed and considering Miriam could like Sobel in return, Feld had his epiphany: He grew comprehensive of Sobel's endurance to escape a land at war and to find any humble source of sustain available. Considering this hardship and his efforts to read books to gain interest from Miriam, Feld understood these endeavors were far more attractive and valuable to Miriam than that of a life of riches with Max. <u>Feld learned about humble love.</u>

abruzzese [7]
Answer:

C) One passage provides objective economic data about the river while the others tell the story of two boys adventuring on its waters.

Explanation:

I believe the answer is C because the first passage provides factual information about the Mississippi River while the other simply uses the river as the story's setting.
