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.

What problem would most likely to occur if a haploid cell attempted to perform meiosis? the cell could not replicate its dna pri
Cerrena [4.2K]

The answer is; the cell could not pair homologous chromosomes during meiosis.

For meiosis to occur, the sister chromosomes pairs line up in the metaphase-plate so that each chromosome of the pair is pulled to the opposite pole by the spindle in anaphase. Therefore, meiosis can only occur in cells with normal ploidy so the ploidy halved by meiosis.

amid [387]

Answer:

6.75l l/min

Explanation:

Streptomycin is extracted  from the fermentation broth using an organic solvent in a counter current staged extraction unit.

for 5 stage counter current staged extraction unit for streptomycin

X5 = 0.2g/l

X0 = 10.0g/l

X5/X0 = 0.02

given

Xn/X0, E, and

n = 5

A estimate of E  can be evaluated directly;

E = 1.8

= LKd/H

by substituting the given values; Kd = 40, H= 150l/min

then we have,

L;L = 1.8(150)/40

= 6.75l l/min
