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

Biology

Gnom [1K]2 years ago

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:

I might be wrong but im guessing 600

Explanation:

Since there is one molecule of glucose used per 6 molecules of carbon dioxide released, if you have 100 molecules of glucose, then you multiply the carbon dioxide by 100 which is 600. Thats what I would say but I might be wrong.

marin [14]

Answer:

The correct answer is - law of dominance.

Explanation:

Law of dominance - Mendel's law of dominance expresses that in a heterozygote, one trait masks the expression of another trait for a similar characteristic. As opposed to the two alleles adding to a phenotype, the dominant allele will be show itself individually and specifically.

Sort the different barriers into their modes of reproductive isolation. A snail with a flat disc-like shell will not be able to
Stella [2.4K]

Answer/Explanation:

Types of reproductive isolation include: temporal, ecological, mechanical, and behavioural.

A snail with a flat disc-like shell will not be able to mate with a snail having a conical shell - this is an example of mechanical isolation, where the animals are physically unable to mate due to incompatible body shapes and sizes.

The reproductive organs of male bush babies do not match with the reproductive organs of females of other bush baby species. - this is another example of mechanical isolation, as the sexual organs will physically not allow reproduction between these species

The mating call of a cricket is not recognized by a cricket of other species - this is an example of behavioural isolation, which results from incompatible mating rituals. I.e. the animals do not respond to each others mating behaviours

The signals sent by a male firefly are not recognized by the female firefly of other species. - this is also an example of behavioural isolation.

Temporal isolation is where species cannot interact because they do not have the same mating seasons or are not active at the same type of day. ?Ecological isolation occurs when two species do not come into physical contact to one another because they access different areas of the habitat. E.g. mating zones, food sources or nesting sites.

viva [34]

Answer:

c. Left atrium

j. right atrium

f. left ventricle

g. right ventricle

Explanation:

The heart consists of four chambers that is two ventricles and two articles.

Blood enters the right atrium goes into the right ventricle.

The right ventricle then pumps blood into the lungs where the blood gets oxygenated.

Pulmonary vein then brings back the blood from lungs into the left ventricle, blood is pumped into the left atrium and out of the heart.

That is the process through which blood navigates in the heart.
