I believe the answer is 1,014
Answer:
In the given case, the brain of the alien would be showing an enlarged region with surface grooves and folds. It is nothing but the cerebral cortex and mainly the neocortex. As the name suggests that it is the latest addition to the brain and is regarded to be originated by the process of evolution.
It is the main region of extraordinary cognitive tendencies like reasoning, thinking, analysis, and other things. As mentioned in the question, that alien is trained like astronauts on the Earth, thus, this neocortex would be certainly found in the brain of the alien.
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: Option C) They would not need to be transported through the body.
Explanation:
Red blood cells are a type of blood cell that have a biconcave disc shape and lack nucleus. They are transported around the body where they distribute oxygen.
Neurons, on the other hand, are a type of cell in the nervous system. They are of different types and are interconnected to one another such that they do not need to be transported at all while they transmit impulses around the body.
Thus, if red blood cells were shaped like the interconnected neurons, there would be no need for them to be transported through the body.
Answer: very small amounts are easier to express as ppm.
Explanation: 1 ppm = 0.0001 %
