Why is milk used as a first-aid remedy for someone who has swallowed a heavy-metal poison?

Answer:

Heavy metal poison specifically due to lead are removed by intake of milk (as it is a source of calcium)

Explanation:

Toxicity produced by heavy metal specifically lead can be removed by intake of calcium metal which is predominantly found in milk. The interaction between lead-calcium subsides the toxicity of lead.  

Both calcium and lead ion i.e Pb(2+) and Ca2+ compete with each other for transportation at the plasma membrane but due to the presence of Ca2+ channels, and the Ca2+ pumps, calcium get preference over lead and hence it is removed from the nervous system.

Human trials have indicated an inverse relationship between blood lead level and calcium intake. While milk isn’t an antidote to let’s say, lead poisoning, the dietary calcium inhibits the lead absorption. This sort of poisoning is incredibly dangerous to the systems of the human body, and the ingredients within the milk help to defend against it. The purpose of the milk is to dilute the ingested poison.

Answer:

Low Enzyme Production is the reason for no breaking down of food.

Explanation:

If the digestion of food did not occur so it means that there is low enzyme production because enzymes are responsible for the breaking down of food substances into simpler ones in order to absorb by the cells for the generation of energy in the form of ATP. So we can conclude that low enzyme production is the only reason for the stopping of breaking down or digestion of food.

alisha [4.7K]
D = m/v

Given:
D: .835 g/cm3
V: 34 cm3
M: ?

M= Dxv

M= .835 g/cm3 x 34 cm3
M= 28.39 g

<u>Answer</u>: Thermal energy---->  a polar bear breaks down stored fat to increase its temperature.

Mechanical energy-------> bat emits and receives sounds to locate prey.

Electrical energy------>eel releases a current to defend itself.

Radiant energy -------->  a firefly produces a green glow from its abdomen to attract mates.

<u>Explanation</u>:

  • <em>Thermal energy</em> is the energy created in the movement of particles that leads to the production of heat and thus, the temperature increases. Since the polar bears break down fat to increase temperature, the energy generated is thermal energy.  
  • The<em> mechanical energy</em> is defined as the sum of energy of motion and   the position of an object  . Thus the energy produced by the bat to locate its prey is mechanical energy.
  • The energy associated with the production of electromagnetic radiation is<em> radiant energy,</em> thus the glow produced by fireflies is a form of radiant energy.
  • The energy produced due to the movement of electrons is electrical energy. Thus, the energy produced by an eel in the form of electric current is <em>electrical energy.</em>
