Of all the elements, helium has the highest first ionization energy figure.</span>
Answer:
c) No, because Celsius is not an absolute temperature scale
Explanation:
converting 5 oC to kelvin which is the absolute temperature scale gives = 273 + 5 = 278 K
and converting 20 oC to kelvin = 20 + 273 = 293 K
the ratio = 278 / 293 = 0.94 approx 1 not 4

Explanation:
Answer:They are all controlled by the human beings.
Explanation:
The selective breeding, cloning and genetic engineering are some of the techniques which is induced by the human efforts.
In case of selective breeding the male and female species having the selective characters are mated with each other so that the offspring produced has the desired characters. It neither requires any enzyme nor uses udder cells.
In case of genetic engineering, the gene of interest is inserted in the bacterial species by the help of vector so that when the bacterial species amplify the gene of interest. This is how the desired products are produced by bacterial species. Example: Insulin production.
Cloning can be defined as another technique made by human beings in which the genetically identical species is made naturally or artificially for the benefit of the mankind.
Answer:
Mg
Explanation:
Mg is above Al on the table meaning it is easier to oxidize.
Fe and Zn are below Al on the table showing they are not as reactive.
