Genetic variation results in different forms, or alleles?, of genes. For example, if we look at eye colour, people with blue eyes have one allele of the gene for eye colour, whereas people with brown eyes will have a different allele of the gene
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: prokaryotic cells
Explanation:
A prokaryotic cell is a cell without a nucleus. Since this is a simple definition I cannot explain much further, but an example of a prokaryotic cell is bacteria.
Answer: Loess is the fine grained material that has been transported and deposited by the wind. The answer is <u>A.</u>
Explanation:

Loess is no larger than 50 micrometers in size. It is coarse in texture like clay, but finer than a grain of salt.
