Explain how are Fe-60 and Ni-60 are related to the formation of our solar system

The Fe-60, (iron-60) is formed during the gigantic scale explosion of the stars. However the amount of the isotope that can be located here on Earth after coming from distant stars is small

The Fe-60 is therefore, a source of evidence that the solar system formed from the after effect of stellar explosions.

The abundance of iron in the universe consists of 90% Fe-56, which has 26 protons along side 30 neutrons.

The Fe-60 however has 34 neutrons and the extra 4 neutrons given the Fe-60 its radioactive properties, such that it decays to form nickel-60 with an half life of 1.5 million years.

The nickel-60 found in meteorites are therefore, more or less the remnant of the radioactive decay of Fe-60 formed during the supernova explosion that likely formed our solar system

Explanation:

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do
