What is the indicator we are using in this titration? in your own words, what is the purpose of grinding the spirulina? should the ground silica and spirulina mixture be suspended in deionized water, exhibit water, or buffer? why? what is the color of the folded phytobilliprotein with the bound cofactor? how do you expect it to change as you add acid or base?

What is the indicator we are using in this titration?

a deep blue indicator

Explanation:

What is the indicator we are using in this titration?

a deep blue indicator

the purpose of grinding the spirulina is to be able to break the cell into smaller particles that can dissolve well in a solution.

when powder spirulina is mixed with silica the cells are easily break even.

Should the ground silica and spirulina mixture be suspended in deionized water, exhibit water, or buffer? Why?

ground silica and spirulina mixture be suspended in deionized water because its dissolved and mixed well in water than any other solvent.

What is the color of the folded phytobilliprotein with the bound cofactor?

A blue color is observed when phytobilliprotein is folded.

How do you expect it to change as you add acid or base?

when a base solvent is use for the solution of silica and spirulina (e.g of base NaOH) is used, the colour obseved will be pale yellow or green color.

when a acidic solvent is use for the solution of silica and spirulina (e.g of base HCL) is used, the colour obseved will be colorless solution.

When a base and acidic solvent is used, it causes a changed in the charge state of the protein and changes the interaction thereby causing unfolding.

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 !
