do fish protect eggs that are unfertilized?

I doubt it. Most fish do not protect their eggs at all. Though, some do.  I doubt they bother with eggs of no potential offspring other than being a food source.

They are indeed maggots.  Cheese is not sterilized before it is processed for consumption.  The eggs likely were on the cheese before you opened it.  The room temp simply provided the appropriate environment for them to hatch.  They may have been from fuit flies.  Had the cheese ever been opened before?  It takes very little to contaminate.

No. Once a fish egg is layed, that means it has formed a zygote, the fusion of sperm and egg. It has no characteristics of a seed and will not grow into a tree.

I take it that you mean "on leaves above the water level", because many species lay their eggs upon subaquatic plants or otherwise attach them to plants as protection. \nThe only fishes I've heard of that lay eggs on leaves are not from Africa but from South America (Amazon basin). The "splashing tetras" (Copella arnoldi) lay their eggs on the underside of objects (including leaves) just above the water and the male parent constantly splashes them with water to avoid dessication.\nI know this is not the answer but I'll keep searching!

The eggs and sperm are reabsorbed by the body if they  can not be used.\n\nLink below will give you all the details.

There are actually quite a few "other animals" that don't lay eggs -- some sharks have a version of live birth, as do many vipers.  Boa constrictor females retain their eggs (they don't actually "lay" them) until they hatch, so the young come out live.  \n\nThere are egg-laying mammals; they're called Monotremes -- the only ones alive today are the duck-billed platypus & the short- and long-beaked echidna.   \n\nAs for the rest of us mammals, we all still come from eggs, but we've developed an awesome internal incubation system -- just think, now we don't have to worry about eggs rolling out of nests, dehydrating, getting too cold, or being carried away by predators!

if there is mosture the sperm and egg can combie but if it can't float is water in produees asexualy

The chicken eggs we eat are unfertilised and not foetuses.  (Although I have heard urban myths where someone has cracked an egg and found a baby chick inside).  In natural circumstances (esp. in the wild), unfertilised eggs are rarely laid.  A rooster will fertilise a hen's egg through mating and the egg is laid and incubated until it hatches into a chick.  Farm hens produce an enormous number of eggs unfertilised for human consumption, as a result of human farming technology.

Well, this isn't a fruit, but here in the US, it is recommended that pregnant women avoid eating salmon due to the potential mercury/other contaminants that the fish ingest. (can't remember which)

Gently place egg in water...observe it floating.

When you carefully analyze the risk of contracting salmonella from raw eggs, you will find that it is actually quite low. A study by the U.S. Department of Agriculture earlier this year showed that of the 69 billion eggs produced annually, only 2.3 million of them are contaminated with salmonella. So simple math suggests that only 0.003 percent of eggs are infected. The translation is that only one in every 30,000 eggs is contaminated with salmonella. Salmonella infections are usually present only in traditionally raised commercial hens. If you are purchasing your eggs from healthy chickens this infection risk reduces dramatically. Remember, only sick chickens lay salmonella-contaminated eggs. If you are obtaining high quality, cage-free, organically fed, omega-3 enhanced chicken eggs, the risk virtually disappears.\nGuidelines To Ensure That You Are Consuming Fresh High- Quality Eggs\n\nYou can go to the American Egg board for a great overview of eggs. \n\nAlways check the freshness of the egg right before you consume the yolk. \n\nIf you are uncertain about the freshness of an egg, don't eat it. This is one of the best safeguards against salmonella infection. \n\nIf there is a crack in the shell, don't eat it. You can easily check for this by immersing the egg in a pan of cool, salted water. If the egg emits a tiny stream of bubbles, don't consume it as the shell is porous/contains a hole.\n\nIf you are getting your eggs fresh from a farmer it is best to not refrigerate them. This is the way most of the world stores their eggs; they do not refrigerate them. To properly judge the freshness of an egg, its contents need to be at room temperature. Eggs that are stored in the fridge and opened immediately after taking them out will seem fresher than they actually are. Eggs that you want to check the freshness of should be kept outside the fridge for at least an hour prior to opening them.\n\nFirst, check all the eggs by rolling them across a flat surface. Only consume them if they roll wobbly.\n\nOpen the egg. If the egg white is watery instead of gel-like, don't consume the egg. If the egg yolk is not convex and firm, don't consume the egg. If the egg yolk easily bursts, don't consume the egg.\n\nAfter opening the egg you can put it up to your nose and smell it. If it smells foul you will certainly not want to consume it.

Eggs sold in the supermarket are unfertilized.  Roosters are necessary to fertilize eggs in order to get baby chickens.  I'm not sure if these eggs can be fertilized at a later time.  Help me out someone.

Depends on the bird. Usually it is inversly proportional to the size of the cache of eggs. Chickens for example lay a great number of eggs because they are flightless and pretty much defenseless. Mortality is high so the species compensates with prodicious egg laying. Interestingly this makes them an excellent livestock choice which has certainly contributed to the survival of the species.

salt water is heavier than fresh water. If the water is salty enough, the egg will float. Otherwise, it will sink.

I don't think you mean development of the zygote....that is a fertilized egg.  Do you mean all the embryological stages after fertilization? There are similarities and differences in all three of these organisms' embryology.\n\nThe starfish zygote and amphibian zygote are both slimy-jelly coated and are vulnerable to fungus-bacterial infections in the water they are laid in, and vulnerable to being eaten by misc hungry aquatic organisms. These eggs are laid and fertilized as a result of external fertilization in the water.  Starfish just release the gametes in the water at a specific time in breeding season without a mating act per se.  If you are standing on a hill above a tidepool while groups of male and female starfish shed their gametes you can see the cloudiness in the water from the huge quantities of sperm and egg they release quasi-synchronistically. \n\nFrogs and other amphibians actually have a mating act called amplexus. The male does all the ribbiting to audition for the job of dna donor.  If she is ok with it, he jumps on the back of the female and he squeezes her eggs out while he releases his sperm on them. Starfish zygotes go thru many many larval stages-metamorphoses (they are part of zooplankton) and eventually mature to the adult on the tidepool rocks.  The bipinnaria larva of echinoderms are famous for their DEUTEROSTOMATE development like other vertebrates-chordates (see below)!\n\nAmphibian zygotes eventually turn into ONE aquatic tadpole larval stage which uses gills and then grow appendages-lungs to be eventually become more terrestrial.  \n\nAmphibians do not have an amnion in their eggs and are therefore anamniotes. Birds and reptiles produce "land eggs" that can resist dessication pretty well and are therefore called AMNIOTES, those who have the amniotic sac to help protect the developing embryo from the drying air on land. The amniotic fluid is in the amniotic sac. Mammals can lay eggs (monotremes) but most are placental mammals who have the amniotic sac in the uterus, but amnion and amniotic fluid with the fetus is not inside a shelled egg like the birds and reptiles.So placental mammals are the most advanced amniotes\n\nOne way these three embryo types do NOT differ: starfish and amphibian and bird are all "deuterostomate" animals.  . All animals you listed on your question are deuterostomate. Most invertebrates are "protostomes. So it is said to be an evolutionary LINK, that the echinoderm-starfish bipinnaria larva shows deuterostomate embryology! "Proto means "first," deutero means "last" and stom means "mouth." Again, both echinoderm bipinnaria larva and chordates-vertebrates (amphibians and birds) are deuterostomate. \n\nWhen embryos change from blastulas to gastrulas, there is an early indentation-invagination process of the tissue to begin the formation of endoderm and the future GI tract from MOUTH to ANUS.  In protostomates, most invertebrates except the echinoderm-starfish group, the mouth is formed first at the first indentation or invagination of blastula to become gastrula, and the anus is formed last.  \n\nIn the deuterostomates, the mouth is formed last and the anus is formed first.  The Echinoderms which includes the starfish, are deuterosomates like the chordates (bird and amphibian), including us humans. Aren't you glad you now know that your anus formed before your mouth?

all eggs are laid even if they are powdered the just have been dehydrated.  also shouldn't this go in the food section

Ya it means the egg was fertilized. I've always thrown them away when this happens.
