Small intestine, That's because they're long which enables a wider work for enzymes and digestive juice.
Bacteria in soil feeds on dead organisms.
Answer:

The correct answers are:
- Methylation of histone tails in chromatin can promote condensation of the chromatin.
- DNA is not transcribed when chromatin is packaged tightly in a condensed form.
- Acetylation of histone tails is a reversible process.
- Some forms of chromatin modification can be passed on to future generations of cells.
- Acetylation of histone tails in chromatin allows access to DNA for transcription.
Histone modifications are post-translational modifications of histone protein that can affect gene expression by altering chromatin structure or recruiting histone modifiers.The most common modifications are methylation, phosphorylation, acetylation and ubiquitylation. All of them affect the binding affinity between histones and DNA and thus loosening (gene activation) or tightening (gene repression) the condensed DNA.
Histone methylation is a transfer of methyl group by histone methyltransferases to lysine or arginine amino acid of protein. Effect of methylation depends on the type of protein that is modified. Demethylation is the reverse process.
Histone acetylation is the process of adding of an acetyl group(by histone acetyltransferases) to histone proteins and it can also activate or inhibit the gene expression. Deacetilation is reverse process.
I believe the answer is Government subsidies. A subsidy is the form of cash payment or a tax reduction. It is normally given to remove some type of burden, and it is often considered to be in the overall interest of the public, given to promote a social good or economic policy. Tax subsidy; the government can create the same outcome through selective tax breaks as through cash payment. For example, suppose a government sends monetary assistance that reimburses 15% of all health expenditures to a group that is paying 15% income tax. Tax subsidies are also known as tax expenditures.
