Answer:
An organism with high fitness has adaptations that are well suited to their environment allowing them survive and reproduce. An organism with low fitness has characteristics that are not well suited to their environment meaning they almost certainly die without reproducing.
Explanation:
These are the five steps in genetic engineering.
- locating and obtaining the DNA of an organism with a particular trait.
- cloning the gene responsible for the phenotype.
- creating a gene with a particular expression pattern.
- transformation, which involves introducing the gene into a crop plant's cells.
- Transgene into a background with affluence.
In the process of genetic engineering, DNA extraction comes first. This is achieved by taking a sample of bacteria that contains the desired gene and subjecting it to a series of procedures that isolate DNA from other components of the cell.

The oxygen-poor blood enters the heart from the body through the SVC, or, the superior vena cava. The oxygen-poor blood then enters the right atrium (RA) of the heart.
Answer and explanation:
Cystic fibrosis occurs due to mutations in the CFTR gene, causing deficient ion transport in patients through cell membranes with a reduction in the amount of water from bronchial secretion.
This decrease makes the secretion more adherent to the bronchial walls and compromises the cleaning of these channels, facilitating pulmonary infections.
The disease also causes the blockage of the pancreas ducts, reducing the arrival of digestive enzymes in the intestines.
For an individual to develop cystic fibrosis by mutations, it is necessary to have both chromosomes 7 with the mutated CFTR gene. This means that a person needs to inherit mutated chromosome 7 from his mother and father.
