Aquarium salt water is prepared to a salinity of 30 ppt (parts per trillion) by dissolving 3.26 kg of salt into 114 L of water.

If you wanted to make 4,000 mL of salt water at the same salinity, how many grams of salt will you need?

Answer:

114 gram of salt is required.

Explanation:

Below are the following given data in the question:

Prepared salinity water = 30 ppt

Weight of salt used = 3.26 kg

The volume of water = 114 L

Below is the calculation.

4000 mL = 4000/1000 = 4L

Let the used = x kg

3.26/114 = x/4L

Now solve for the x.

x = 0.114 kg or 114 gram

vesna_86 [32]

Answer:

Shivering thermogenesis.

Explanation:

The rate of heat production is increased by increasing muscle contraction by movement is shivering thermogenesis because nerve impulses are transmitted to the skeletal muscles by the hypothalamus which will result to contractions that will produce heat.

Shivering thermogenesis is Contraction-mediated heat production High intensity shivering activates large muscles and produce more glycolysis which is then use as the main source for heat production

Glucagon, a peptide hormone, is upregulated when blood sugar levels are low. Which molecules in or on the plasma membrane would
Arlecino [84]

Answer: Receptor protein.

Explanation:

The receptor protein on the cell surface would enable a cell to respond to glucagon. The glucagon binds to the GPCR on the liver and muscle cells and is known as glucagon receptor.

This receptor then stimulates cells to release glucose into the blood stream. Another hormones involved during this process is glucagon like peptide 1.

It works by binding to another GPCR which is GLP-1 receptor found on the pancreatic cells.
