The correct answer is "coarctation of the aorta". In coarctation of the aorta, there is an abnormal narrowing of the aorta, most commonly in the abdominal aorta, which compromises blood flow from going into the lower extremities. Patients with coarctation of the aorta most commonly presents with tachypnea as this is a high pressure congenital heart defect which makes breathing harder for the baby; diminished femoral pulses and poor lower body perfusion as the narrowing compromises blood flow. In physical examination, there will be a narrow ankle-brachial index, or the difference between the pulse pressures of the ankle (lower extremity) and the brachium (upper extremity).
Answer:
Anterior end
Explanation:
You have a pretty good shot at guessing this, because the earthworm has very little going on at the posterior end except the anus. And you probably saw this in lab, too.
I've attached a picture of the earthworm anatomy. Worms can't smell in the strictest sense, but they can use their receptors as kind of a combo smell-taste thing, and those are located in the anterior end.

Answer:
Allows to give rise to different organs.
Explanation:
Since all the cells in our body have developed from a single cell, "the egg or ovum fertilized by a sperm", all of them are identical, that is, they have exactly the same instructions, but depending on the organ they form part, they will use only part of the information or another. This is known as cell specialization.
Thus, the nerve cells possess the information necessary to form hair and the cells that form hair possess the information necessary to form nerves. However, once specialized, nerve cells will form nerve tissue and hair cells will form hair.
In this way, being different recipes, the cells give rise to different organs.
