polyp should be the answer
Answer:
Blood leaves the heart through the pulmonic valve, into the pulmonary artery, and to the lungs. Blood leaves the heart through the aortic valve, into the aorta, and to the body. This pattern is repeated, causing blood to flow continuously to the heart, lungs, and body.
Explanation:
Answer: Option (A) is the correct answer.
Explanation:
It is given that the unknown substance is solid at 15 degree celsius. When further heated then heat energy breaks the bond between molecules of the solid.
As a result, temperature remains constant until all the bonds are broken down to convert the solid into liquid.
Hence, the constant 17 degree celsius temperature shows that the solid is melting and after it completely melts then it converts into liquid at 23 degree celsius.
Thus, we can conclude that the statement its melting point is 17 °C, is correct about the unknown substance.
