Answer:
occurred an aneuploidy (monosomy)
Explanation:
Aneuploidy can be defined as a chromosomal aberration in which the chromosome number is abnormal. In an aneuploidy, the number of total chromosomes in daughter cells is not an exact multiple of a haploid set, by either gaining or losing chromosomes during mitosis. Aneuploidies are common in cancer cells and in different types of chromosome disorders. Moreover, monosomy is a type of aneuploidy in which daughter cells have a single chromosome copy instead of the two copies found in diploid cells. For example, Turner syndrome is a monosomy caused by the loss of the X chromosome.
Sonar uses sound waves in order to detect and locate objects in the water. The speed and detectable range of sound waves are impacted by the medium they are travelling through. Ocean water, the medium that sonar travels through, includes characteristics such as temperature, density, and salinity. These elements affect the nature of the medium, and thus affect the sound waves used for sonar detection.
The dog was conditioned to it. The unconditioned stimulus (food) triggered the unconditioned response (dog salivating). By ringing the bell before bringing the food, the bell (once a neutral, but now a conditioned stimulus) triggered the dog's salivation. The dog's response is a conditioned response because he learned to associate the bell with food.
