What else can I help you with?
What are two limitations of the biological species concept?
Two limitations of the biological species concept are that it cannot be applied to asexual organisms or fossils, and it may be difficult to determine reproductive isolation in some cases where different species can still interbreed and produce viable offspring.
Which change is most likely to lead to competition among organisms?
An increase in population size, a decrease in available resources, or introduction of a new species are changes that can lead to competition among organisms as they vie for limited resources like food, water, or territory.
2 Scientists can tell whether organisms are closely related by comparing their?
2.Scientists can tell whether organisms are closely related by comparing their ____.(1 point)DNA, I had this on my test too and I answered DNA and got it right.
How do we know if two animals are in the same species?
If the two organisms are able to interbreed with each other then we know that they are from the same species because the individuals in a species are able to interbreed and produce fertile offsprings.
Name two factors that will determine whether a non-native species becomes an invasive species?
Two factors that can determine whether a non-native species becomes invasive are its ability to reproduce rapidly and outcompete native species for resources, and the absence of natural predators or controls in its new habitat.
HOW do you know 2 organisms are not part of the same species?
Because malaria
What happens when to two organisms attempt to occupy the same niche?
Massive competition occurs when 2 organisms have the sane niche. The organisms are 2 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.
How are 2 organisms the same species?
If two organisms are able to mate and produce fertile offspring, then they are of the same species.Horses and donkeys are two different species because if they mate, they produce a mule which is sterile (not fertile). This shows horses and donkeys are of different species.
Fossils of a species of bird are found in layer 3 Which layer is most likely to have organisms that lived at the same time as the bird species?
Layer 2
What are the biological sublevels of biotic community?
The biological sublevels of a biotic community include individual organisms, populations of the same species, and communities of different species interacting in the same habitat. These sublevels represent different levels of organization within the community, from individual organisms to larger groupings of species.
What two levels of classification are used to name organisms?
The genus and species are the final 2 classification that determine a scientific name for an organism
What happens when two organisms attempt to occupy the niche?
Massive competition occurs when 2 organisms have the sane niche. The organisms are 2 species.
How do you do a karyotype?
-Determine the gender of the individual. -To tell if 2 cells belong to the same species. -To detect the genetic abnormalities in Prenatal diagnosis.
The organisms with the greatest number of species are?
Insects are the organisms with the greatest number of species, with estimates ranging from 2 to 30 million species. Other diverse groups include bacteria and fungi.
What generalization can you make about identifying how closely organisms are related?
if 2 or more organisms have more than one of the following the same, they are closley related: kingdom, phylum, class,order,family,genus,and species
What is the one way in which scientist get information about the evolutionary history of species?
One very important way that information is compared in the evolutionary history of a species is to use DNA. By checking how much is the same between species, we can see if those species are closely related or not. Our own DNA and that of the great apes are only different in about 1-2%.
