<u>Answer</u>:
An observation that would allow for identification of the cell as an animal cell rather than a plant cell would be "the centrioles migrating".
<u>Explanation</u>:
Centrioles start moving towards the opposite ends of the cell, whereas the microtubules starts moving from the centrioles and gets attached to the centromeres of chromosomes. The microtubules that have been projecting from the centrioles on opposite poles of the cell are connected to individual centromere and further form into spindle fibers. After the accumulation of chromatin into chromosomes in prophase, resulting in the breaking down of the nuclear envelope, or membrane. In case of animal cells, the centrioles present at the nucleus starts to separate and go to the opposite poles of the cell. As the centrioles transfer, a spindle is seen to be formed between them.

Answer:
<em>The correct option is D) decreased ice causes less energy to be reflected</em>
Explanation:
Observations have shown that ice has the ability to absorb less solar radiation and reflect back most of it. On the other hand, liquid water absorbs more solar energy and reflects back a little of it.
Hence, the lesser the ice will be, the lesser will be the solar energy being reflected back. If the solar energy is not reflected back in adequate amounts it can cause global warming and the atmosphere of the Earth to be heated.
