why is the cuurent populations experiencing famine

A plant makes its own proteins but an animal synthesizes the proteins it consumes as food.

cell wall

A rigid structure that surrounds the cell membrane and provides support to the cell

annual plant bears fruit

Borlaug

Green Revolution

Agriculture was not a developed science in ________ . That country's machinery, technology, and crop varieties did not advance with new developments in other parts of the world.

India

Proteins

Nutrients the body uses to build and maintain its cells and tissues

are Photosynthesis and respiration simple in design

Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water.
