What are the two main types of biotechnology?

The two main types of biotechnology are indeed red biotechnology and green biotechnology, making the choice focused on these areas the correct answer.

Red biotechnology refers to the application of biotechnology in the fields of medicine and pharmaceuticals. This includes processes such as genetic engineering to develop new drugs, as well as tissue engineering and gene therapy. The focus is on understanding and controlling biological systems to improve health outcomes and address diseases.

Green biotechnology, on the other hand, is primarily associated with agricultural practices. It involves the use of biotechnological methods to enhance crop yields, improve nutritional content, and create pest-resistant plants. This area addresses food production challenges and aims to promote sustainability in agriculture, ensuring that production methods are both efficient and eco-friendly.

These two domains are foundational to the broader understanding of biotechnology, which encompasses various applications across health, agriculture, and environment sectors. Other color-coded biotechnologies mentioned in the options focus on different specialized fields rather than the major, foundational classifications identified in the correct choice.
