Hard-shelled organisms absorbed calcium and carbonate iron and use them in making their hard shells which are calcium carbonate. When these organisms die, there shells are used in the formation of limestone rock. Limestone rocks are a huge store carbon. When acid rain reacts with limestone, these trapped carbon are released to the atmosphere thereby causing an Increase in atmospheric carbon.

Conclusively, the accumulation of limestone rock and subsequent reactions with acids such as acid rain has resulted in an increased atmospheric carbon throughout the years.

If a heterozygous woman without hemophilia had children with a man with hemophilia, what is the chance that their first child wi

dybincka [34]

Answer:

1/2

Explanation:

let the alleles of the heterozygous woman without hemophilia be = Xhx

And the alleles of the man with hemophilia be XhY

If both XhY × Xhx; we have:

Xh Y

Xh XhXh XhY

x Xhx xY

XhXh and XhY are affected by the diseases

Xhx is a carrier

xY is normal

∴ the probability(chance) that their first child will have the disease is 2/4 of the total offspring

=1/2

∴ the probability (chance) that their first child will have the disease is 1/2
