Tubal ligation is a surgical procedure that permanently prevents pregnancy by blocking the fallopian tubes.

Biotechnology has various applications in agriculture, including the development of pest-resistant crops, production of biofuels, and creation of synthetic hormones.

One potential risk of genetically modified crops is the development of resistant pests, which can lead to increased agricultural challenges.

A potential risk associated with the use of GMOs is the development of resistant pests, which can lead to increased pesticide use.

Phloem is responsible for the transport of food, primarily in the form of sucrose, from the leaves to other parts of the plant.

Primary producers, such as plants, convert solar energy into chemical energy through photosynthesis.

Bt cotton is a genetically modified organism (GMO) that has been engineered to express a bacterial toxin, making it resistant to certain pests.

Microbial fermentation can produce antibiotics, vitamins, and alcohol, among other products.
