Is it true or false that Eukaryotic cells do not have a nucleus?
Yes, it is possible for a Eukaryotic cell to have no nucleus. An example of a cell without a nucleus is the mammalian red blood cell. However, Eukaryotic cells without a nucleus, like red blood cells, are unable to replicate. This is why red blood cells need to be continuously produced in the bone marrow.
What is the importance of the flagella?
Without this it's possible that organisms will die. Certain unicellular organisms need sunlight or a certain temperature to survive. So this is very important.
Why do all cells stain purple in the flagella stain but not in the gram stain?
The gram stain uses a decolorizing product so it is possible to differentiate between the gram and the gram cells. Gram positive cells stain purple in color.
If a eukaryotic gene is inserted in prokaryotic cellwould gene expressed its characters?
Yes. Both eukaryotes and prokaryotes use the same system of codons (they speak the same 'language'). For example, GGG will be translated to glycine in a human and in E. coli bacteria. Therefore, as long as the eukaryotic gene is attached to the appropriate prokaryotic gene regulation elements, a prokaryotic cell will be able to translate and express the gene. The most common method to accomplish this is to put the eukaryotic gene in a 'vector' (most commonly a plasmid of bacterial origin), and then transform the bacteria with this vector.This is how humulin (human insulin) was first prepared by recombinant DNA technology. The eukaryotic genetic information (human DNA) was inserted into prokaryotic plasmids, and the bacteria then synthesized insulin.
How is H-pylori contracted?
Helicobacter pylori is relatively easily spread by a person to person contact. Asian custom of using the same dipping bowl for the chop stick is a proven way to hand it around the family. Kissing also can spread it, and it is possible to contract it from water, food (due unhygienic food preparations, handling etc). It is even suggested by some expert, that you can get introduced to it from a wide range of animal hosts.

What is the actual observation that provides the strongest evidence for the possible origin of eukaryotic cytoskeleton?
homologs of actin and tubulin are found in certain bacteria.
Is it possible for a eukaryotic cell to have more than one nucleus?
If you're talking about a normal eukaryotic cell, then no, it is not possible. But if the cell is undergoing cell division, the original nucleus will formed into two nuclei in the cell at one moment of time but that is because the cell is going to split into 2 daughter cells and each daughter cell needs a nucleus.
Are kidney cells prokaryotic?
No, kidney cells are eukaryotic.All cells in the human body are eukaryotic except one. Red blood cells are, strictly speaking, prokaryotic because they do not have a nucleus but this is a structural adaptation that allows the cells to carry as much oxygen as possible so they are still listed as eukaryotic.
What preparations would a Jewish boy need to do before his bar mitzvah?
Preferably he should learn as much Torah as possible. Specifically, he should learn whatever Torah-portion he'll be reading.

What continental congress was called for peace and made preparations for war?
The First Continental Congress originally called for peace. When peace was not possible a declaration of war was issued and a declaration of independence.
Why is central planning needed?
Central planning is needed to mitigate possible negative outcomes when a natural, or man made disaster occur. Central planning makes preparations to provide the basic human needs to the population of a given area.
What does it mean to dream of your husband who died pushing open doors for you?
The dream illustrates the dreamer's feeling that the deceased husband had conscientiously made preparations and taken care of arrangements, to make the transition (passing through the doors) as easy and smooth as possible for her.
What is the name of the cell without a nucleus?
Prokaryotic cells do not have a nucleus, their genetic material is free in the cytoplasm as they do not have a need for compartmentalisation like more complex Eukaryotic cells that carry out more internal chemical mechanisms.Some Eukaryotic cells do not have a nucleus though, for example a red blood cell ejects its nucleus when mature as it no longer has a need for it and it needs as much room as possible for storing oxygen.
Why was a warning issued in Massachusetts for Hurricane Earl?
Warnings were issued in areas where hurricane conditions are likely within 36 hours. Earl is expected to pass very near Nantucket later on Friday. The following statement was recently issued by the National Hurricane Center for these warned areas: FOR THOSE UNDER A WARNING...NOW IS THE TIME TO RUSH TO COMPLETION PREPARATIONS FOR THE PROTECTION OF LIFE AND PROPERTY. EVACUATE IF DIRECTED TO DO SO BY LOCAL OFFICIALS...OR IF YOUR HOME IS VULNERABLE TO HIGH WINDS OR FLOODING. FOR INTERESTS AT PORTS...DOCKS...AND MARINAS...URGENTLY COMPLETE PRESCRIBED PREPARATIONS ACCORDING TO YOUR EMERGENCY OPERATIONS PLAN FOR TROPICAL CYCLONES. IF YOU LIVE ON A BOAT...MAKE FINAL PREPARATIONS FOR SECURING YOUR CRAFT BEFORE LEAVING IT. BE SURE TO ACCOUNT FOR THE POSSIBLE CLOSURE OF BRIDGES AND CAUSEWAYS. REGARDING ANY COASTAL WATERS UNDER A WARNING...SMALL CRAFT SHOULD REMAIN IN PORT AND WELL SECURED. FOR THOSE UNDER A WATCH...CONTINUE WITH YOUR PREPARATIONS AND LISTEN FOR POSSIBLE WARNINGS. REGARDING ANY COASTAL WATERS UNDER A WATCH...SMALL CRAFT SHOULD RETURN TO PORT OR SEEK SAFE HARBOR. DETERMINE THE BEST STRATEGY FOR SECURING YOUR CRAFT. CLOSELY MONITOR NOAA WEATHER RADIO OR OTHER LOCAL NEWS OUTLETS FOR OFFICIAL STORM INFORMATION. LISTEN FOR POSSIBLE CHANGES TO THE FORECAST. FOR ADDITIONAL PRECAUTIONARY AND PREPAREDNESS INFORMATION...PLEASE REFER TO THE DETAILED RECOMMENDATIONS RELATIVE TO YOUR LOCATION AS FURTHER DESCRIBED BY YOUR LOCAL NATIONAL WEATHER SERVICE OFFICE AND LOCAL EMERGENCY MANAGEMENT. ALL PREPARATIONS FOR HURRICANE EARL SHOULD BE COMPLETED BY NOON FRIDAY.
