Who is generally credited with the discovery of cells?

Which of the following characteristics is NOT a basic property of cells?

Who proposed that life forms should be categorized into three distinct evolutionary lines rather than the traditionally accepted two lines of prokaryotes and eukaryotes?

The first compound light microscopes were constructed by the end of the sixteenth century. What characteristic defines a compound microscope?

The term _____________ describes the ability of a life form to synthesize its organic molecules from other organic nutrients.

Which of the following are considered to be eukaryotes?

The original cell which arose billions of years ago is referred to by some evolutionary biologists as the __________.

In some cases, an infecting virus does not lead to the death of the host cell, but instead integrates its DNA into the DNA of the host cell's chromosomes. Integration of the viral DNA can have different effects; for example, the infected cell might exhibit normal behavior until exposure to a stimulus that activates the dormant viral DNA, triggering production of viral progeny that bud off of the infected cell or a loss of control over growth and division leading to malignancy. Such an infection is referred to as ______ infection.

Volvox is characterized by possessing ____________ cells.

The term used to describe the life forms capable of withstanding a variety of harsh environments is:
