Answer:
The superior vena cava is formed by the merging of the right and left brachiocephalic veins.
Explanation:
The superior vena cava is one of the main veins of the human body, it is responsible for receiving blood from the head, neck, upper chest and upper limbs. It is formed by the union of the right and left brachiocephalic veins, they originate from the junction of the subclavian vein with the internal jugular vein to form the right and left brachiocephalic venous trunk, both trunks join or merge into a single trunk and they form the superior vena cava, which flows into the upper part of the right atrium.
Answer:
ATP consists of an adenosine molecule
bonded to three phophate groups in a row.
In a process called cellular respiration, chemical energy in food is converted into chemical energy that the cell can use, and stores it in molecules of ATP.
This occurs when a molecule of adenosine diphosphate (ADP) uses the energy released during cellular respiration to bond with a third phosphate group, becoming a molecule of ATP. So the energy from cellular respiration is stored in the bond between the 2nd and 3rd phosphate groups of ATP. When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy.
