Protoctistia includes a diverse range of organisms with varying characteristics, making classification challenging. Some members exhibit traits found in multiple kingdoms, leading to debate over their placement. Additionally, advancements in molecular studies have revealed evolutionary relationships that differ from traditional classification based solely on observable characteristics.
A group of organisms that has been reclassified is the prokaryotic group Archaea. Previously considered a type of bacteria, they were reclassified as a separate domain due to genetic and biochemical differences.
The two main systems used to classify biomes are the Holdridge Life Zones classification system, which consider climate, vegetation, and temperature data; and the Whittaker biome classification system, which categorizes biomes based on precipitation and temperature.
Cloning of humans has not been achieved successfully. Ethical concerns and technical challenges have so far made it illegal and difficult to accomplish.
Environments can be classified into two main categories based on evolution: natural environments, which have not been significantly impacted by human activities and have evolved over long periods of time, and human-modified environments, which have been altered by human actions and interventions, leading to changes in the natural evolutionary processes.
Many organisms are very similar, especially at the species level when dealing with same family and genus. Because of this, and because of the sometimes unclear relationships and development periods of each, some organisms might be difficult to classify, e.g. whether they are merely subspecies, or are different species, or are actually from a different genus but same family.
because eugleana is hard to classify
because Aristotle had a system to classify organisms on earth that only included plants and animals like human beings. The reason why euglena would have been hard was because it is capable of photosynthesis, which is natural for a plant type organism, but it was also capable of moving which was not something that plants would do but something humans or animals would do.
There has never been a rating to classify movies on their qualities.
No. Emperor Hirohito tried to advance the cause and respect of his people. Furthermore, he did not have as much control over Japanese political affairs as did Tojo and his supporters. More importantly, it is very difficult to classify people as "Good" or "Evil" in a simplistic dichotomy. Could Hirohito have been better, probably. Could he have been worse, probably as well.
it would be difficult beacause they didnt know how to swim
The westward expansion may have been difficult for Georgia due to the terrain. There are mountains and swampland to the west of Georgia.
You can't the group has already been formed . There was an audition to be in the group in 2008 .
They typically have wings. Unless they've been launched from a slingshot or catapult, in which case wings are optional.
Waking up in the morning.
small, cryptic, or live in hard-to-reach habitats. Additionally, some organisms may have unique adaptations or genetic variations that make them difficult to classify. The vastness and complexity of Earth's ecosystems also contribute to the challenge of identifying all organisms.
it has made unification difficult but can u answer why its made it difficult
An azidoglycoside is a glycoside in which a hydroxyl group has been replaced by an azido group.
