There are many known positive outcomes of genetic engineering both in plant and animals. Among these outcomes include: a. elimination of diseases; b. most desirable traits guaranteed to exist; c. crops that can be pest and disease resistant; d. longer shelf life for plants.
Answer:
2. A change occurs in the environment.
4. Poorly adapted individuals have decreased survivorship.
1. Well-adapted individuals leave more offspring than do poorly adapted individuals.
3. Genetic frequencies within the population change.
Explanation:
The natural selection theory was developed by Darwin to explain how evolution occur within a population. The environment is in constant state of changes and always select for organisms that are better adapted to it.
Poorly adapted organisms gradually reduce from the population as a result of decreased survival while well-adapted individuals multiply and contribute more to successive generation.
Well-adapted individuals pass on the adaptive alleles to their offspring, eventually leading to a change in gene frequencies within the population.
Hence, the sequence of events is 2, 4, 1 and 3.
Most becomes carbon dioxide and the rest of it often becomes fossil fuels such as coal
