Answer:
the egg begins to shrink
Explanation:
During the 5 minutes that the egg is in the concentrated salt solution he would notice that the egg begins to shrink. This occurs due to the process known as osmosis which happens when a solvent passes a semipermeable membrane towards where there is a higher concentration which in this case would be within the egg. Since the egg would contain more water than the salt solution causing it to shrivel and shrink.
Answer: it doesn't
Explanation: Why? The aorta is the largest artery in the body. The aorta begins at the top of the left ventricle the heart's muscular pumping chamber. The heart pumps blood from the left ventricle into the aorta through the aortic valve. Three leaflets on the aortic valve open and close with each heartbeat to allow one-way flow of blood. The aorta is a tube about a foot long and just over an inch in diameter. The aorta is divided into four sections:
• The ascending aorta rises up from the heart and is about 2 inches long. The coronary arteries branch off the ascending aorta to supply the heart with blood.
• The aortic arch curves over the heart, giving rise to branches that bring blood to the head, neck, and arms.
• The descending thoracic aorta travels down through the chest. Its small branches supply blood to the ribs and some chest structures.
• The abdominal aorta begins at the diaphragm, splitting to become the paired iliac arteries in the lower abdomen. Most of the major organs receive blood from branches of the abdominal aorta.
Like all arteries, the aorta's wall has several layers:
• The intima, the innermost layer, provides a smooth surface for blood to flow across.
• The media, the middle layer with muscle and elastic fibers, allows the aorta to expand and contract with each heartbeat.
• The adventitia, the outer layer, provides additional support and structure to the aorta.
the first value that biosphere provides is genetics which provides variety of genes in population. the second value that biosphere provides is species which is an abundance of each species in a biological community. the last value the biosphere provides is the ecosystem with variety of ecosystems that are present in the biosphere.
Answer: Pseudoscience such as astrology are almost untestable and have no basis in science. Science must follow the scientific method.
step one- Construct a Hypothesis
step two- test that hypothesis
step three- analyze your findings and draw a conclusion.
