Carbon dioxide is emitted as a by-product of clinker production an intermediate product in cement manufacture, in which calcium carbonate (CaCO3) is calcinated and converted to lime (CaO), the primary component of cement. CO2 is also emitted during cement production by fossil fuel combustion.
<span>A scientist wants to create a florescent ornamental fish. He needs fluorescence similar to that of a firefly. Which of the send processes would help him create this fish?
The correct answer is </span><span>transformation of the DNA of a fish using a fluoroscent gene from a firefly. In order to do so, he would have to use the gene of the firefly as a reference in order to transform the DNA of a fish.</span>
<span>A heterozygous individual is if a mutation occurs in just one copy of the gene.
If both copies of the gene are mutated than the individual is homozygous</span>
