...As a result of a symbiosis between prokaryotic and eukaryotic cells. The theory is that the mitochondria and the chloroplasts were prokaryotic cells inside the eukaryotic cells which is called endosymbiosis. There is evidence for this because plastids and mitochondria have double membranes like prokaryotic cells and they also have their own genetic material.

Hope that helps and is in decent english as I studied it in spanish

Blababa [14]

Answer:

A response is a _reaction to a stimulus. • A stimulus is anything that can cause an individual to respond or react. • Stimuli can be _internal or external.

Explanation:

A change in the cellular make up of an organisms due to response or reaction to a stimulus is called a response. This response can be due to a stimulus inside the body , or due to effect of an external ( stimulus) object on the body-stepping on a sharp pin.

In either cases, the stimulus is receive by the receptors, which transfer the stimulus through the sensory neuron to the inter neuron in the CNS, for the motor neuron to bring an effective response at the effectors.

<span>The correct answer: copper is important in the synthesis of collagen.</span>
Copper activates an enzyme called lysyl oxidase that's required for collagen maturation.Lysyl oxidase catalyzes the formation of aldehydes from lysine residues in collagen and this results in cross-linking collagen (stabilization of collagen fibrils).

Answer:

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.
