The Green Revolution in India was a wheat-centric revolution that led to the higher-yielding varieties of wheat.The production of wheat increased by more than three times between 1967–68 and 2003– 04 while the overall increase in the production of cereals was only two times. On account of this, it is said that the Green Revolution in India is largely the Wheat Revolution.

A chloroplast is an organelle unique to plant cells that contains chlorophyll (makes plants green) and is responsible for enabling photosynthesis. The chloroplasts conduct photosynthesis, where the photosynthetic pigment chlorophyll captures the energy from sunlight and converts it and stores it in the energystorage molecules while freeing oxygen from water.

Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. It plays vital roles in digestion, heart and muscle function, brain development and maintenance of bones. It increases heart rate, cardiac contractility and cardiac output and also promotes vasodilation, which leads to enhanced blood flow to many organs.

Biodegradable waste includes any organic matter in waste which can be broken down into carbon dioxide, water, methane or simple organic molecules by micro-organisms such as bacteria. Biodegradable waste can be used for composting or a resource for heat, electricity and fuel by means of incineration or anaerobic digestion.

Because interbreeding can destroy the genetic integrity of a species, causing it to become progressively infertile or extinct, evolutionary changes in anatomy and biology developed to prevent interbreeding between species. The specific term is Reproductive Isolation, which acts to prevent some, any, or all stages of reproduction from occurring. Reproductive Isolation is very important in keeping animal species separated.
