Answer: There are many foods who have trace elements like seafood, legume, vegetables, tomatoes, bananas, eggs, fishes, meat.

Their five mainly functions are accept or receive electrons in redox reactions, act like cathalytic centers which are necessaries to live, control biologics process like the hormon activation and gen expression, provide stability, 3d structures in important molecules.

Explanation: Trace elements participate in redox reactions because they have acid-base components which alkalize o acidify the way, protecting the organism from free radicals.

Biological sources which are controlled by trace elements are:

  • assimilation of ATP
  • methabolic sources relationed with insuline
  • oxygen transport in the organism
  • stomach acid formation
  • 3d structures from important moleculess are mantained by balance of electrons which make up the atoms from the molecule.

The density of liquid mercury is 13.6 g/mL. What is its density in units of ? (2.54 cm = 1 in., 2.205 lb = 1 kg)
nalin [4]

Correct question

The density of liquid mercury is 13.6 g/mL. What is its density in units of lb/in​3​? (2.5 cm = 1 in., 2.205 lbs= 1 kg., 1000 g =1 kg, 1 mL = 1 cm³)

Answer:

\rho0.4916\ lb/in^3

Explanation:

Given that;-

The density = 13.6 g/mL

Also, 1 kg = 2.205 lb

1 kg = 1000 g

So, 1000 g = 2.205 lb

1 g = 0.002205 lb

Also,

1 in = 2.54 cm

1 in³ = 16.39 cm³

1 cm³ = 1 mL

So,  1 in³ = 16.39 mL

1 mL = 0.061 in³

The expression for the calculation of density is shown below as:-

\rho=\frac{m}{V}

Thus,

\rho=\frac{13.6\ g}{1\ mL}=\frac{13.6\times 0.002205\ lb}{0.061\ in^3}=0.4916\ lb/in^3
