Venous blood from the ankle travels and goes through tibial vein, popliteal vein, femoral vein, external iliac vein, common iliac vein, inferior vena cava to the heart (right side). From the heart to the right side of the brain, blood goes through the aorta and the brachiocephalic artery. The brachiocephalic artery the then divides into the right common carotid artery and the right subclavian artery and both supply the right side of the brain.
Answer:
The answer is Force.
Explanation:
Force is a push or push of a particular directions with a particular object.
The vacuoles in a plant cell are much more larger and take up a large portion of the cell but animal cells vacuoles tend to be smaller. The plant cells vacuole is permanent when the animals is temporary. A plant cells vacuole is formed by budding off the membrane, the animal cells vacuole is formed by the organelle called the Golgi body.
Answer:
Explanation:
My best bet is DNA methylation at the site of Tweedledum's leptin gene or Histone Acetylation at the site of Tweedledee's gene.
B/c DNA methylation is a process by which methyl groups are added to the DNA molecule. Methylation can change the activity of a DNA segment without changing the sequence. When located in a gene promoter, DNA methylation typically acts to repress gene transcription. So this is probably repressing Tweedledum's leptin gene trancription which is not happening in Tweedledee.
Additionally, Histone Acetylation at site of Tweedledee's gene increases her trancription b/c Histone acetylation causes DNA to be more accessible and leads to more transcription factors being able to reach the DNA. Thus, acetylation of histones is known to increase the expression of genes through transcription activation.
