Answer:
The culture might not be stained properly or the culture might be too old.
Explanation:
Gram staining is done to differentiate between gram-positive and gram-negative bacteria according to the difference in their cell wall. In gram staining, the gram-positive bacteria appears violet and gram-negative bacteria appear pink in color.
Therefore if a pure culture contains have both red and purple cocci that it can be concluded that the gram stating was not done properly like too much destaining was done or too much safranin was used or maybe the culture is too old so that cell wall of some bacteria degrades.

Explanation:
Answer:
a. bottleneck effect.
Explanation:
A bottleneck effect occurs when some adverse environmental conditions such as typhoons and famine reduce the population size considerably. The allele frequencies of the population are changed. As the population grows again, the gene pool has different allele frequencies than the original population. During population growth, some harmful alleles may become more abundant resulting in a rare disease such as achromatopsia. Therefore, the given population represents the bottleneck effect.
Data organization refers to the method of classifying and organizing sets of data to make them more useful. Analysis is a detailed examination of something. It is what you do with the data you collected. Based on this, we can say that B, counting the number of fish for each species, and D, transferring the data from the fish counter to a computer program would both be examples of data organization and analysis.
Answer:
The correct answer is - Honeycreepers arose from a single species that migrated to Hawaii and adapted to different niches over time.
Explanation:
All Hawaiian honeycreeper bird species share similar muscle and skeletal structures. This suggests that all Hawaiian bird species arose from a common ancestor and evolved due to different environmental conditions such as eating particular foods for particular species.
It is believed to be a single species of honeycreeper who migrated from the mainland to Hawaiin island and adapted to different niches over time by the process known as natural selection.
