Answer:
As the bubble is a spherical entity, the probability of total internal reflection from the watery films is high due to its curvature. As a result, most of the light rays get reflected and therefore the air bubble shines brightly with some sparkling in water
Ductus Arteriosus is a blood vessel normally present in fetuses during development. The blood vessel is designed to bypass the pulmonary artery and brings blood to the Descending Aorta, as the fetus cannot breath through the lung (being as they are fluid filled). This is normally not a problem because oxygenated blood comes from the mother's blood supply.
Patent Ductus Arteriosus, is what happens when that vessel does not close. While not as dangerous as other congenital defects. However, because there is still a bypass, blood that normally need to be oxygenated by going through the pulmonary arteries to the lungs, can be diverted and placed into the blood stream without vital oxygen. This condition may eventually lead to CHF (congestive Heart Failure) and Pulmonary Hypertension if not treated.
False,
In order to start labor, estrogen increases and progesterone decreases.
Estrogens are a class of hormones that are essential for women's healthy sexual and reproductive development. They are sex hormones as well. The majority of estrogen hormones are produced by a woman's ovaries, however minor quantities are also produced in modest amounts by the adrenal glands and fat cells.
Progesterone is a member of the progestin drug class (female hormones). By lowering the level of estrogen in the uterus, it functions as a component of hormone replacement treatment. By substituting for the natural progesterone that some women lack, it helps to initiate menstruation.
