TUI Boiled meat broth

7. How did Pasteur solve Spallanzani's problem of limiting exposure to air?

8. What purpose did boiling the meat broth serve in both the Spallanzani and Pasteur

experiments?

9. How do the Redi, Spallanzani, and Pasteur experiments disprove the hypothesis you

wrote in Question 3?

10. Today, we use a process of heating liquids to prevent spoiling by bacteria and other

microorganisms, pioneered by one of the three scientists mentioned above. What is that

process called and for what food it is used?

11. What facts did Redi's, Spallanzani's, and Pasteur's experiments establish? What broader

scientific understanding about life did the experiments explore? How does the example of

these experiments demonstrate science as a way of knowing?

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up
