    I typed wrong. So the upper one is the cone and the lower ones are the rods. They are laballed as well. The cones are thicker.

    if the ventricles contract from bottom upwards it means the blood will be pumped into the aorta and pulmonary artery. this is important because this way all the blood is pushed up at once so there is more blood pumped at each stroke (stroke volume is high). lastly if it contracts from top to bottom blood would be pushed down essentially damaging cardiac cells... i cant think of anything more...
    many thx im sure thats more than enough

    the three down are rods and the top one is cone.
    2 or 3 rods are usually connected to one bipolar neurone , unlike cones .

    DNA methylation is a method when CH3 methyl groups are attached to specifc parts of DNA and this essentially switches off the gene to which they are attahced, it is a reverse process of transcription factors (which increases gene expression) DNA methylation decreases gene expression and transcription.

    DNA methylation is the process of adding methyl -CH3 groups to some bases in the DNA. It is a method of inhibiting gene expression.
