Sure, here are the step-by-step solutions: 1. The Paramecium chromosome, also known as the prochromosome, is made up of a double-stranded DNA molecule. 2. Unlike eukaryotic chromosomes, the DNA in the prochromosome is not associated with histone proteins. 3. The DNA in the prochromosome is circular and does not have free ends like linear DNA molecules do. 4. The prochromosome is also present in the mitochondria and chloroplasts of Paramecium, and is therefore referred to as an organelle prochromosome.

Parthenogenesis is the development of a female egg into a new individual without the contribution of a male set of chromosomes.
In a hypothetical pond, two populations of fish are found; one reproduces through sexual reproduction, the other through parthenogenesis. Initially, the parthenogenetic fish are a larger population when the pond is first studied. However, researchers soon observe that the parthenogenetic fish are more frequent hosts for a new blood-borne parasite than the sexually reproducing fish. As a result, the sexually reproducing population increases and the parthenogenetic population decreases.
Which of the following best explains the reason for the shift in population numbers?
  1. Sexual reproduction increases genetic variation. Some individuals in the sexually reproducing population will be adapted to a change in environment, in this case, the addition of a new parasite. These individuals will survive and reproduce at a higher rate than those affected by the parasite.
  2. The asexual fish are more susceptible to the parasites because they are an all female population, and typically less aggressive. The sexually reproducing population is protected by aggressive adult males fighting off the invading parasites.
  3. The asexually reproducing fish are intentionally reducing their population density as a mechanism to slow the spread of the parasite.
  4. The sexually reproducing population can reproduce faster than the parthenogenesis population, allowing them to produce so much offspring that not all can be affected by the new parasite.
