Answer:
are heterotrophs.
Explanation: This means they eat things outside of themselves instead of producing their own food.
West Nile lead to a decline in susceptible avian and human hosts, with a subsequent decline in the number of cases since 1997
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.
