Honestly, we could come up with reasons all day, but the simple fact is that eukaryotic cells are up first. C'est la vie. Eukaryotic Cell Structure and Function A cell is defined as eukaryotic if it has a membrane-bound nucleus. Any organism composed of eukaryotic cells is also considered a eukaryotic organism.

Best Time to Visit Cuba. The best time to visit Cuba is between December and April. The weather at this time is very pleasant and dry. The temperature at night can even drop down to below 20 degrees in these months. The tourist peak season runs from December to April, peaking around Christmas and on Easter weekend.
Low and Shoulder Seasons. The high season begins to wane in mid- to late April, and from then through May is a popular lower-cost time to visit the Caribbean. Likewise, the period between the end of hurricane season and beginning of peak season -- late October through November -- is often a good time to visit. Keep in mind, however, that many resorts, restaurants and shops close in October and November. Not surprisingly, the lowest season for travel to the Caribbean is in the middle of hurricane season.
