سوال : Which is the only continent that is also considered as a country?
جواب :
Australia
Australia is typically regarded as the smallest of the seven continents. There is no universally accepted definition of the word "continent." The lay definition is "One of the main continuous bodies of land on the earth's surface." (Oxford English Dictionary). By that definition, the continent of Australia includes only the Australian mainland, and not nearby islands such as Tasmania or New Guinea. From the perspective of geology or physical geography, however, a "continent" may be understood to include the submerged adjacent area (the continental shelf) and the islands on the shelf, which are taken to be structurally part of the continent. By that definition Tasmania, New Guinea and other nearby islands are part of the Australian continent, since they sit on the same continental shelf. These islands are separated by seas overlying the continental shelf — the Arafura Sea and Torres Strait between Australia and New Guinea, and Bass Strait between mainland Australia and Tasmania.
When sea levels were lower during the Pleistocene ice age, including the last glacial maximum about 18,000 years ago, the lands formed a single, continuous landmass. During the past ten thousand years, rising sea levels overflowed the lowlands and separated the continent into today's low-lying semi-arid mainland and the two mountainous islands of New Guinea and Tasmania

سوال : The first sound of heartbeat is made after what action
جواب :
It is caused by the sudden block of reverse blood flow due to closure of the atrioventricular valves, i.e. mitral and tricuspid, at the beginning of ventricular contraction, or systole. When the pressure in the ventricles rises above the pressure in the atria, venous blood flow entering the ventricles is pushed back toward the atria, catching the valve leaflets, closing the inlet valves and preventing regurgitation of blood from the ventricles back into the atria. The first sound results from reverberation within the blood associated with the sudden block of flow reversal by the valves]].
The first heart sound is produced by the turbulant flow against the closed AV valves .
First heart sound is caused by atrioventricular valves - Bicuspid/Mitral and Tricuspid .
