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.

Aspecies has evolved an asexual mode of reproduction by having offspring develop from unfertilized eggs. which of the following will be true of this species' response to natural selection? there will be more deaths from natural selection because there is no mutation. there will be less genetic variation from recombination and a risk of not adapting quickly to environmental change. the species will increase in numbers because genetic variation is increased. the species will compensate for loss of genetic variation by hybridizing with other species. there will be fewer deaths from natural selection because sexual recombination always leads to extinction.
