As a result in the attempts to reduce the amounts of carbon dioxide and methane, green house gases will lessen and the ozone layer will slowly stop being damaged. Global Warming may also calm down as the main cause for global warming is the exposure of Greenhouse gases to the ozone layer.
Hope this helps!
The prenatal is the stage of the development of the foetus from the fertilized cells towards the whole organism. In the embryo stage, the cells divide and the organs are formed.
<h3>What are the stages of prenatal division?</h3>
In the embryo stage of the foetus development the formation of the cells and their division occurs, it is the early stage of the development where the multicellular diploid organism results in the formation of the distinct organs with specialized functions.
Blastocysts are the early group of cells formed after zygote formation and is important for the implantation in the uterus lining.
A zygote is the immediate result of egg and sperm fusion. This cell is the earliest cell that is diploid and is formed just after fertilization.
Therefore, option A. embryo is the stage in which the formation of the organs occurs.

Since each parent contributes 1 allele to their offspring, we can expect a even distribution of 4 allele combinations in the offspring of these fish. They are
s1s2 = s1 from 1st parent, s2 from 2nd parent
s1s4 = s1 from 1st parent, s4 from 2nd parent
s3s2 = s3 from 1st parent, s2 from 2nd parent
s3s4 = s3 from 1st parent, s4 from 2nd parent
Since both the s1s4 and s3s2 offspring have 5 units of color, that would indicate that 50% of their offspring will have 5 units of color.</span>

Answer:
D. Nucleic acids attach to the bases in the DNA.
Explanation:
Transcription begins when an enzyme called RNA polymerase is added to the DNA template and begins a new chain a new chain to produce complementary RNA. During the RNA synthesis transcription takes place, then the cap and tail is added and then splicing occurs. RNA polymerase moves from the 3 'end to the template strand creating the RNA-DNA double helix or similar the base sequences. This makes a chain with each sugar by the set of bonds called phosphodiaster linkage. Then, the enzyme unwind the DNA and begins the synthesis of RNA. Therefore, D. Nucleic acids attach to the bases in the DNA.
