Answer: C
Explanation:
If immigration and emigration numbers remain equal, decreased birthrate could cause a slowed growth rate
.
Decreased birthrate always affects the numbers in terms of population.The less births there are, the smaller the number of people. Even if the death rate remains constant a decreased birthrate will slow growth of population.
Answer:
D. Small population size
Explanation:
Hardy-Weinberg equilibrium requires the presence of a large randomly mating population. Small population size makes the population more likely to deviate from the Hardy-Weinberg equilibrium due to sampling error or chance events occurring during the genetic drift. Large population size ensures that the population maintains the constant allele frequencies over generations, that is the Hardy-Weinberg equilibrium.

Explanation:
Most spiral galaxies contain a central bulge surrounded by a flat, rotating disk of stars. The bulge in the center is made up of older, dimmer stars, and is thought to contain a supermassive black hole. Approximately two-thirds of spiral galaxies also contain a bar structure through their center, as does the Milky Way.

Cells within the body are properly arranged and their production uses up resources of the body. For example, red blood cells use iron while being produced. The body must dispose of cell properly to maintain the orderly arrangement of cells; for example, if dead skin cells were not removed, we would lose feeling in our skin due to the layer of dead cells. Moreover, the body must work to minimize wastage. This is why some of the iron from red blood cells is removed and reused.
