Carnivores (animals that eat other animals/humans for food)
Answer:
Vacuole
Explanation:
The vacuole is one of the largest organelles in a plant cell because it holds the water, food, and waste of the cell.
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.
Answer:
Temperature will increase
Explanation:
As we know
Where KE represents the Kinetic Energy, R represents the gas constant and T represents the temperature.
As the kinetic energy increases, the velocity of the gas molecules increases due to which the gas molecule start moving rapidly and hence exerts higher amount of force on the wall of the container in which it is kept.
The higher force leads to generation of higher pressure and hence the higher temperature.
