We are talking about chemical reaction here. In a chemical reaction, substances that react are called reactants, and substances which are formed are called products. Atoms in the reactants break their bond, rearrange themselves and form new bonds to make the product. So no atoms are added or removed, which is called law of conservation of atoms/mass.
Answer: (I HOPE THIS HELPS) Antlions experience competition when there is a scarcity of food and few spaces to burrow in the sand. This happens during their larval stage when there is an overlap on their reproduction where the large ones consume the small ones for survival.

Excess Vitamin A is most harmful to an embryo during the first and second months of pregnancy.

The process of RNA editing is the alteration of the sequence of nucleotides in the RNA after it has been transcribed from DNA, but before it is translated into a protein. RNA editing occurs by two distinct mechanisms:<em><u /><u>Substitution</u> <u>editing </u></em>and <u><em>Insertion/</em></u><em></em><u><em>deletion</em></u><em> <u>editing</u></em>.
<u><em>Substitution editing</em></u> is the chemical alteration of individual nucleotides. These alterations are catalyzed by enzymes that recognize a specific target sequence of nucleotides:
*Cytidine Deaminases that convert a C in the RNA to uracil.
*<em />adenosine deaminases that convert an A to inosine,which the ribosome translates as a G.<span>Thus a CAG codon</span><span> (for Gln) can be converted to a CGG codon (for Arg).
<em><u>*Insertion/deletion editing</u></em><em><u /></em><u /> is the insertion or deletion of nucleotides in an RNA.
These alterations are mediated by guide RNA molecules that base-pair as best they can with the RNA to be edited and serve as a template for the addition( or removal) in the target.</span>
