Natural selection is the mechanism which proved species?
have chromosomes.
What is the nuclear division mechanism that produces gametes?
In eukaryotes, a nuclear divison mechanism called meiosis precedes the formation of gametes and, in many species, spores. It is the basis of sexxual reproduction.
What happens to species that attemp to occupy the same niche?
In an ecosystem, a niche is a very specific role that a species can play in that system. When two species attempt to fulfill this exact same role, their prey becomes much more scarce, and one will eventually force the other out.
How do euglena grow?
I don't believe they actually grow but they do split in half to grow their species
What happens when two organisms attempt to occupy the same niche-?
Massive competition occurs when 2 organisms have the sane niche. The organisms are 2 species.
Natural selection is the mechanism which proved species?
have chromosomes.
The lack of a mechanism hampered the acceptance of the idea that?
Species change over time
Can microevolution form a new species?
Yes. In fact, microevolution, or allelic variance, is the mechanism by which new species emerge. Such an emergence is part of what some people call macroevolution. In other words, microevolution is the mechanism by which macroevolution is produced.
Which mechanism do the different organism populations found across the tundra exemplify?
Species diversity :)
What is the process called where the environment in which a species lives causes a change to the collective genes of that species?
Natural selection, which is the mechanism for evolution.
Where do you find the chassis number on a sandman?
You can attempt to, but seeing that the sandman is a protective endangered species with aggressive behavior, i wouldn't attempt to do so
What influence did speciation have on Darwin's development of Natural Selection?
The influence of providing an explanatory mechanism for what was obvious to Darwin; species arose and species went extinct.
What is one limitation of the morphological species concept?
There is no known mechanism for the introduction of new genetic material.
How many species of worm exsits?
there are actually 35,000 species.
What species are spiders?
Spiders are arachnids which is actually a class not a species. (Example: Mammals, Birds, Fish, etc.) A species would be a type of spider. There are actually over 40,000 species of spiders that we know of.
What is the nuclear division mechanism that produces gametes?
In eukaryotes, a nuclear divison mechanism called meiosis precedes the formation of gametes and, in many species, spores. It is the basis of sexxual reproduction.
Why hasn't anyone seen a new species appear in biological evolution.?
Evolution doesn't work like that. Since evolution is an ongoing, continuous mechanism, every species that we see is the 'newest' species in its particular line
