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: See explanation
Explanation:
In meteorology, station models simply refers to the symbolic illustrations which depicts the weather that occurs at a reporting station.
Meteorologists use station model as it helps in revealing and communicating certain information about the weather of a particular area. It also helps in reporting various data and temperatures. .

Answer;
C) the amount of time that the two species have been evolving apart
Explanation;
-Scientists can use relaxed-clock methods to deal with variation in the rate of the molecular clock. By measuring the patterns of evolutionary rate variation among organisms, they can also gain valuable insight into the biological processes that determine how quickly the molecular clock ticks.
- The molecular clock hypothesis states that DNA and protein sequences evolve at a rate that is relatively constant over time and among different organisms. A direct consequence of this constancy is that the genetic difference between any two species is proportional to the time since these species last shared a common ancestor.
Answer:
B. glucose – NADH – electron transport – O2
Explanation:
This is the sequence from glycolysis in which glucose molecules are split down to pyruvate, to oxidative phosphorylation.
During this process the electrons are released from glucose molecule as it is oxidised multiple times as pyruvate, and other molecules formed subsequently in Kreb's cycle, until the oxidative phosphorylation is reached .
The makes the carrier molecules to be reduced.Thus NAD→NADH,FAD→FADH .
The electrons from above are transferred in hydrogen atoms to matrix by these co-enzymes.Where the H is split to electrons and protons.
The electrons for the ETC, produce the PMF for transporting protons into the intramembrane space.
The concentration of protons generated the electrochemical gradients which is needed to produce energy for for phosphorylation of ADP with Pi to form ATP by ATpase synthase.
The electrons moves as chain,and this is finally accepted by oxygen as the final electron acceptor.
