- The environment needs to change in order to natural selection to occur.
Reason:
Because, Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.
2. Population has some genetic variations.
Reason:
Genetic variation is essential for natural selection because natural selection can only increase or decrease frequency of alleles that already exist in the population. Genetic variation is caused by:
mutation and random mating between organisms
3. Nature select organism with specific traits to survive and reproduce.
Reason:
According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
Answer:
As my study programme is concerned with the field of biotechnology, I hope that by the end of the proposed study programme, I will be able to gain knowledge about the molecular tools and the concepts and trends in genome editing. I shall be able to perform techniques such as PCR, gel electrophoresis, cell culturing easily. I would be able to grasp better knowledge in the fields of plant biotechnology, animal biotechnology, Industrial biotechnology and marine biotechnology.
Answer:
organisms from one trophic level are consumed by organisms from the next level.
Explanation:
Answer: hope that helps
Explanation: Scoliosis is a sideways curvature of the spine that occurs most often during the growth spurt just before puberty. While scoliosis can be caused by conditions such as cerebral palsy and muscular dystrophy, the cause of most scoliosis is unknown.
