I think the veins absorb the photons because they're located at the top part of a leaf while the stomata that serves as the leaf's lungs are found at the under side.
The endoplasmic reticulum (particularly the rough endoplasmic reticulum) has ribosomes attached to it, a type of organelle that synthesizes protein. It also itself folds proteins in sacs on its surface called cisternae.
The question, however, most likely is referring specifically to ribosomes, as these are the organelles primarily responsible for the production of proteins. The endoplasmic reticulum is mostly to assist the ribosomes and transport the proteins once they are properly folded.

Explanation:
BCG (bacille Calmette-Guerin) is the vaccine which is given for tuberculosis. This vaccine is used in many countries in which the chances of spreading Tb is high in children which causes meningitis and miliary disease in children.

Answer-Sea flows act a lot of like a transport line, moving warm water and precipitation from the equator toward the posts and cold water from the shafts back to the tropics. In this manner, sea flows manage worldwide atmosphere, assisting with balancing the lopsided dissemination of sun powered radiation arriving at Earth's surface.
