In fetal life, the lungs are not expanded, so most of the blood from the right ventricle is shunted from the pulmonary artery to the aorta through the patent ductus arteriosus. With a few breaths the lungs expand, and blood flows from right ventricle to pulmonary artery into the lungs. Withdrawal of circulating prostaglandin from the mother plus bradykinins released from the expanding lung of the infant cause the ductus to close over a few minutes to hours. The closed ductus remains as the ligamentum arteriosum.
The sun heats the land and oceans unevenly, creating areas of upwards and downwards moving air as well as pressure differences. This causes air to flow from one area to another. For hurricanes the sun heats the ocean, causing some water to evaporate. The water vapor powers convection in storms which can then <span>strengthen and organize to form hurricanes. Hope this helps:)

A frog gets rid of it's urine through the kidneys because the heart pumps blood throughout the body, the lungs are used to take in O2 molecules and gills are use to filter out the hydrogen in HO2 so they can breathe under water. However the kidneys are part of the waste disposal system (what makes us need trip to the bathroom ever now and then) therefore that is the answer.<span />
The three laws of inheritance are :
Law of Dominance. Law of Segregation. Law of Independent Assortment.
what is law of dominance?
First, according to the Law of Dominance and Uniformity, some alleles—variants of a specific gene located at the same chromosomal locus or location—are dominant over other alleles for that gene.
As it relates to genetics, the term "inherited" describes a feature or variation that is encoded in DNA and passed from parent to child during reproduction. The laws of Mendelian genetics govern inheritance. A will needs to be admitted to probate in order for the inheritance procedure to start. The probate court examines the will, approves an executor, and formally distributes assets to recipients in accordance with the terms. The executor will pay off any outstanding obligations of the deceased prior to the transfer
