Because the hydrogen will also be combusted in the reactions, so in this case the answer will be:
CH4+2O2-CO2+2H2O
Answer:
1. Some forms of chromatin modification can be passed on to future generations of cells.
2. Acetylation of histone tails is a reversible process.
5. DNA is not transcribed when chromatin is packaged tightly in a condensed form.
3. Acetylation of histone tails in chromatin allows access to DNA for transcription.
4. Methylation of histone tails in chromatin can promote condensation of the chromatin.
Explanation:
Chromatin is a structure formed during the packaging of the DNA structure which is formed by the histone proteins and DNA.
1. The chromatin at some position highly is condensed called heterochromatin whereas at some position is not condensed called euchromatin. The heterochromatin sine highly packaged is inactive for transcription.
2. The acetylation is the addition of the acetyl group which can also be removed by deacetylase enzyme, therefore, is a reversible process.
3. The methylation adds a methyl group to the nitrogenous base and suppresses the transcription.
Thus, the selected options are correct.
Determination and willpower
Your answer is D. Anther. The stamen is a part of the flower that is “in charge” of the production of pollen, but the anther is the part in the stamen that actually produces the pollen.
<span>True. Pocket mask is otherwise known as CPR mask, pocket face mask is a device used for the artificial ventilation during a cardiac arrest. When giving aid the mask should be applied to the patient's face using thumbs of both hands. Then stand on one side of the victim and give rescue breaths.</span>
