Can microevolution lead to macroevoultion?
Given the opportunity for reproductive isolation between subpopulations to develop, macroevolution seems like an inevitable consequence of microevolution. Not only can speciation occur (and not only is it observed): it's hard to imagine how it could not occur.
What types of evolution are there?
Basically, there's only one type: the shifting in allele frequencies in populations over the generations, driven by reproductive variation, differential reproductive success, and various molecular mechanisms in genetics. There are however numerous distinct phenomena associated with this mechanism, and different patterns to the way it affects populations, depending on circumstances. If one looks at the different 'modes' of speciation, for instance, even though they all follow from the same basic mechanisms, there are allopatric speciation, peripatric speciation, parapatric speciation, and sympatric speciation, each achieving the same thing through the same mechanisms but via slightly different paths.
Is passive transport able to occur against the concentration gradient?
No, passive transport cannot occur against the concentration gradient. It only moves substances from an area of high concentration to an area of low concentration.
Osmosis can only occur if water travels through the what?
Osmosis can only occur if water travels through the semi-permeable membrane. This will cause water to cross the lipid bilayer.
How many different beliefs of evolution are there?
There are multiple theories of evolution, but two main perspectives are the theory of microevolution focusing on small genetic changes within a population over time, and the theory of macroevolution which explains broader evolutionary changes leading to the emergence of new species. These perspectives are supported by various evidence from genetics, paleontology, and other scientific disciplines.

What do scientist mean when they say that species the only natural rank in classification?
They mean that species are a fundamental category of taxonomic classification, ranking below a genus or subgenus and consisting of related organisms capable of interbreeding.
Why only plants and animals are included in the taxonomic classification?
TAXONOMIC CLASSIFICATION is the study that deals with classification of living organisms only hence the plants and animals are the only living organisms on earth

How do you see the category tree of a particular category in Wiki Answers?
I am not sure you can find a category on Wiki Answers website. The only thing you can do is search for the questions.
