Cell theory is based on a series of discoveries. In 1655. Robert Hooke coined the
word "cell" from his investigations of cork cells. Almost two hundred years later,
Schleiden and Schwann proposed the cell theory that states that:
All life forms are made from one or more cells.
The cell is the smallest form of life.
In 1859 Louis Pasteur's experimental work provided the data to add a third element
to the theory. Pasteur's work included the study of microbes in the fermentation of
beer and wine. This led to the process of pasteurization, which revolutionized the
food industry. While studying the microbes involved with fermentation, Pasteur
began to develop his theory of disease and the ability of these unseen pathogens to
multiply
Pasteur's research, in general, provided an important addition to cell theory. That is,
Ocells can be easily killed and made harmless.
all diseases arise from cells.
sterilization and pasteurization both kill cells.
Ocells give rise to other cells.

In german cockroaches, curved wing (cv) is recessive to normal wing (cv+). bill, who is raising cockroaches in his dorm room, finds that the frequency of the gene for curved wings in his cockroach population is 0.6. in his friend joe’s apartment, the frequency of the gene for curved wings is 0.2. one day joe visits bill in his dorm room, and several cockroaches jump out of joe’s hair and join the population in bill’s room. bill estimates that, now, 10% of the cockroaches in his dorm room are individual roaches that jumped out of joe’s hair. what is the new frequency of curved wings among cockroaches in bill’s room? 0.69 0.4 0.5 0.31 0.20
