Give 3-5 pieces of evidence to support why cloning is bad.

Cloning may cause long term health defects, a study by French scientists has suggested. A two month old calf, cloned from genes taken from the ear of an adult cow, died after developing blood and heart problems.

The cloning process seemed to have interfered with the normal genetic functioning of the developing calf, according to the researchers whose findings are reported in the Lancet (1999;353:1489-91).

Cloned sheep, cows, and mice have been known to die before or shortly after birth. But the latest case highlights for the first time the long term damage that the cloning process may cause.

It is likely to cast fresh doubts over the safety and efficacy of cloning, which has so far been controversial largely for its ethical dimension. The study could lend weight to warnings that any attempt to clone humans might carry considerable health risks.

“Our observation should be taken into account in debates on reproductive cloning in human beings,” warns Dr Jean-Paul Renard, of the national institute for agricultural research near Paris, who led the study.

The calf that died had been cloned from a skin cell extracted from the ear of a 15 day old calf, itself cloned from a cow embryo. The “offspring” seemed to develop normally for the first month, after being treated with diuretics for an enlarged heart.

But rapid depletion of its red and white blood cells caused its condition to deteriorate. The calf was treated with iron supplements but it died from severe anaemia at the age of 7 weeks. At necropsy researchers found that the calf’s lymphoid tissues—the thymus, spleen, and lymph nodes—had failed to develop normally.

Cloning has regularly hit the headlines since February 1997, when researchers in Scotland successfully cloned a sheep, known as Dolly, using DNA from the mammary cell of an adult ewe. Until then, mammals had been cloned only from genetic material from embryos.

Explanation:

So cloning, all in all, is bad because it may cause health problems.

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.
