Answer:
At the end of telophase, two new daughter cells that are exact replicas of the beginning cell will be completed.
Explanation:
- Mitosis is the process of cell division in reproduction process where one parent cell give rise to two daughter cells having the same replication of parent cell.
- Telophase is the final stage of the mitotic division.
- In telophase the cytoplasm is divided into two daughter cells along with all its contents.
- The genetic make up of these daughter cell reflect the same character as the original parent cell.
Answer: C. A natural disaster, such as a hurricane, struck the island.
A limiting factor is a resource or ecological condition because of which growth and distribution of an organism or group of organisms living in an ecosystem limits. A limiting factor can be of either physical or biological in nature. A limiting factor restricts organisms from occupying their fundamental niche. Examples of limiting factor are resources, stress due to overcrowding, disease or parasite and a natural disaster. According to the condition mentioned natural hazard can be the only limiting factor to limit the population at such considerable rate. Natural disaster is a physical limiting factor which has catastrophic impact of populations of different species living in an ecosystem. It has the potential to wipe out several inhabitants in one drastic event. Therefore, a natural disaster, such as a hurricane, struck the island can be a most likely explanation for the changes that the scientists observed.
