Francessco Redi's experiment led to a new theory

Although many scientists believed in spontaneous generation, two scientists (Redi and Pasteur) disproved this theory.

Using your microscope, you discover a structure and you wonder if it is alive. You conduct a series of experiments and determine that it contains all the circled components in the concept map below. Would you then consider the structure to be "alive"? Why or why not? (Select the one correct answer.)

Review the section "Investigating Life: The Orchid and the Moth." Insects of species A, B, and C and flowers of species 1, 2, 3, and 4 live in your backyard. You hypothesize that only insect A can reach the nectar of flower #4. You remove all other flowers from your yard to see what happens to the insect populations. What data would support your hypothesis?

Consider what additional sentences you could add to the Survey the Landscape concept map. Each of the six sentences below contains italicized terms that represent the concepts currently in the Survey the Landscape concept map. The bold term is the concept that you are adding, which is connected to the concept map with a connecting phrase. Which of the six new sentences is true? (Select all correct answers.)

In the tutorial, an experiment examining the effect of brewing temperature on coffee taste was discussed and is illustrated below. Match each component of the experiment to its correct description.

What aspect of this graph shows that the difference in bitterness scores for very hot water and cool water is not due to random chance?

A scientist hypothesizes that the temperature at which alligator eggs are incubated will determine the sex of the young alligator. The scientist proposes to store alligator eggs at various temperatures and count the number of male and female alligators that result in each case. Which of the following is/are true in this experiment? (Select all that apply.)

A species is classified into one of three domains depending on which of the five qualities of life it exhibits. True or False

What term is the least associated with science?

Review the section "Investigating Life: The Orchid and the Moth." Suppose that you are a scientist comparing the energy that orchids use for developing flowers to the energy that orchids use to produce nectar. Your research produces the following graph. These data make you curious if orchids that allocate less energy to producing nectar (and therefore produce less nectar) reproduce less frequently. When you set up your next experiment based on the information in this graph, what might be your hypothesis?

Macromolecules are built from _________ which link together to form ________
