Answer: Pulmonary veins.
Explanation:
Pulmonary vein receives oxygen-rich blood from the lungs into the left atrium where it is pumped into the left ventricle, the aorta and then further distributed to the rest of body.
Answer:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
Inflammatory response can be defined is a reaction of the body to injury or destruction of tissues. This reaction serves to dilute, destroy or simply wall off the agent causing the injury and is localized around the area of injury.
Inflammatory response takes place in the following steps:
1. Tissue damage caused by injury or bacterial infection is detected.
2. Vasodilators and chemotactic factors such as histamine are released.
3. As a result, there is increased capillary permeability and blood flow to the area.
4. There is migration of phagocytes to the site of infection.
5. Phagocytes and specific serum proteins attack and destroy bacteria.
6. Inflammation dies down once intruder has been destroyed.
<span>They have served their purpose and are no longer needed by the plant.
The plant has "served" their purpose, they have fully grown fruit and they don't need a plant to help them grow anymore. Like when a apple falls out of a tree, they're done being developed.
Hope this helped! :)</span>
