<h2>Answer:</h2>

Reaction for observation: Sodium Hydroxide + Copper Sulfate

Full reaction:

2NaOH + CuSO4 --> Cu(OH)2 + Na2SO4

Observations Before Interaction:

Sodium hydroxide is a turbid solution and copper sulfate is in form of bright blue crystals.

Observations After Interaction:

When their solutions are mixed with each other, a pale blue precipitate of basic copper hydroxide & a solution of neutral salt sodium sulphate will be formed.

Was Mass Conserved?

Yes, mass was conserved.

The Law of Conservation of Mass states that "mass cannot be created or destroyed, but changed into different forms".

Hence mass was conserved.

<h3>Part 4.</h3><h3>.Proof of a Chemical Reaction</h3>

The proof of the reaction is the appearance of pale blue precipitates of of basic copper hydroxide & a solution of neutral salt sodium sulphate.

aleksklad [387]

Answer:

The data from the experiment support the claim that the similar regulation of carbohydrate metabolism by hepatocytes occurs when the cells are treated with growth hormone or insulin results from the activation of different signaling pathways

Explanation:

If we take a look on the graph, it shows increase in the phosphorylated protein when the growth hormone or insulin is applied to the cells with the passage of time. At 15 minutes , it reaches to its highest level but after 15 minutes of addition of growth hormone and insulin, the level of phosphorylated protein decrease when the time exceeds from 15 minutes to 240 minutes. So it is concluded that growth hormones or insulin increase the level of phosphorylated protein.
