A chicken is a sexually reproducing organism that undergoes meiosis to produce gametes. Meiosis is a type of cell division that involves the production of daughter cells (gametes) that have their chromosomal number reduced by half.
Hence, if the somatic or body cell of the chicken being ingested by Amanda contains 78 chromosomes, it will undergo meiosis to produce a sperm or egg that has 39 chromosomes i.e. reduced from diploid (2n) to haploid (n).
Somatic or body cells are diploid and are denoted by 2n number of chromosomes. During meiosis, specifically after meiosis I in cell division, the chromosome number is reduced to half the number of that of the somatic cell, and is referred to as haploid, which is denoted by n number of chromosomes.
Therefore, if the somatic cell of the bird has 78 chromosomes, the sex cell (unfertilized egg or sperm) would contain half of the number of chromosomes of the somatic cell = 39 chromosomes.
Pleurisy is a medical condition caused by the inflammation of the pleura membranes. The pleural membranes are vital part of the respiratory system. These membranes which surround the lungs and lines the inner chest wall, help to give cushion and reduce friction in the lungs. When the pleural membranes become inflamed, the surfaces become tough and sticky, thereby causing the sharp pain the person feels in the chest while breathing.
A conditioned stimulus is the one which was previously a neutral stimulus but hen it gets paired with the unconditioned stimulus it leads to a conditioned response.
The learned response which is produced in response to a neutral stimulus is the conditioned response.
In the given condition the smell or taste of a chicken salad causes Allison to feel nauseated and hence, the taste or smell of a chicken salad is the conditioned stimulus which generates a conditioned response which in this case is nausea.
