Blood vessels can shrink down again - vasoconstriction. This reduces heat loss through the skin once the body's temperature has returned to normal.
Bronchoconstriction happens when smooth muscles around the lungs constrict and block the flow of air in the lungs.

Risk of large scale production:
1. With an increase in production, there can become managerial problems. Workers can become lax, making of decisions become difficult and communication between workers become hard.
2. A large scale operation, needs technical tools like machines. Finance to buy machines can become a problem and hamper growth.
Risk of Genetically modified plants

2. They can produce side effects. Engineered plants, can lead to development of new toxins, carcinogens and deficiencies of nutrition.
