The answer is D) Structural
That is because we can automatically cross A out, and B is not the answer because ionic compounds aren't polyatomic. Poly atomic atoms are covalent and have no charge. While on the other hand, ions have a charge.
Also, C is not the answer because the molecular formula for glucose is <span>C6H12O6, that leaves us with choice D.

I can pretty much conclude that D is the answer because you can see that the picture, it has a structure for the compound. Its showing us how the atoms are bonded and structured.
Answer:
A peloidal packstone with large areas of chalcedenous void filling. Sometimes chalcedony is clear and translucent giving the chert a clotted or splotchy appearance. Occasional fossils including Peneropolids and Sorites. Vuggy, grainstone or packstone fabric.
Explanation:
;p your welcome, aha.
Answer: Companies are cutting down trees to make space for factories and produce paper products.
Explanation: when people finish using paper products they throw them away and the paper products get burned, and that produces carbon dioxide
Answer:
- New seedlings: histone acetylation
- After cold exposure: histone methylation
Explanation:
Vernalization is an adaptive mechanism whose objective is to ensure that flowering occurs only after winter (i.e., after cold conditions). In certain plants, this process (vernalization) suppresses the expression of genes that encode repressors of flowering. In <em>Arabidopsis</em>, vernalization is associated with histone modifications at <em>FLC</em> chromatin. The <em>FLOWERING LOCUS C </em>(<em>FLC</em>) is a MADS-box gene that acts as a repressor of flowering in <em>Arabidopsis</em>. Epigenetic modifications control the expression of the <em>FLC</em> gene. The <em>FLC</em> gene is expressed at low temperatures due to histone acetylation at <em>FLC</em> chromatin, and thereby the expression of <em>FLC</em> mRNA transcripts ensures that the <em>Arabidopsis</em> plant cannot flower. Subsequently, as the <em>Arabidopsis</em> plant is exposed to cold, <em>FLC</em> is repressed by the accumulation of trimethylation on lysine 27 of histone 3 (H3K27me3), thereby allowing it to flower when temperatures become warmer.
