Answer:
Atrioventricular valves.
Explanation:
Heart is the muscular organ of the body and acts as the pumping organ of the body. Human heart is not bigger than the fist and the human heart is divided into four chambers.
Heart murmur may be defined as the swishing sound that are made during the blood flow. This represent the heart problem. The bicuspid valve of heart is atrioventricular valve. The damage in the atrioventricular valve causes the heart murmuring.
Thus, the answer is atrioventricular valves.
The 3 phases of interphase can be broken down into the first growth phase of the cell - G1 phase. Then the S phase, where DNA replication and or DNA synthesis occurs to duplicate the number of chromosomes in the cell. Followed by the G2 phase, an additional growth phase and where specific protein come into play along with organelle and cellular component duplication.
Answer:
Yes. Cells have 'cell receptors' that are used to receive messengers like hormones to communicate. Cell receptors have specific shapes that fit the shape of the messenger that they want to receive. Organs like the pancreas send our these messengers to the cells to order them to do different functions.
Chemical reaction hope this helped :)))
