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
1. They can become contaminants. The cross pollinated plants and seeds can travel, and contaminate the gene pool. Thereby, threatening future generations of plants.
2. They can produce side effects. Engineered plants, can lead to development of new toxins, carcinogens and deficiencies of nutrition.

Answer:
Enzymes attached with the body of substrate and speedup the reaction.
Explanation:
Enzymes attached with the body of substrate i. e. starch and increase the speed of break down and when the substrate is broken down, these enzymes detached from the substrate. Enzymes are the chemical substances present in the body of organism which helps to speedup the process of digestion. The digestion of starch starts from the mouth with the help of salivary enzyme and this starch is converted into smaller molecules which can be absorbed by the cells.
Answer:
C Phloem transports glucose to the plant, and stomata release oxygen
Explanation:
A Stomata take in water,sunlight, and carbon dioxide and release oxygen - this is false, the stomata are for gas exchange (taking in carbon dioxide and releasing oxygen). They do not take in water and sunlight
B Phloem transports water, stomata take in carbon dioxide, and chlorophyll absorbs sunlight - this is false, while it is true that stomata take in carbon dioxide, and chlorophyll absorbs sunlight. phloem does not transport water, that is the xylem.
C Phloem transports glucose to the plant, and stomata release oxygen - this is true. Stomata takes in carbon dioxide and releases oxygen, and phloem transport the products of photosynthesis throughout the plant
D Xylem takes in water, sunlight and carbon dioxide and releases oxygen - this is false. Xylem does take in water, but not sunlight, carbon dioxide or oxygen
