Taxonomy is the branch of Science, in which
we study the Classification of Organisms. On discovering an unknown organism,
begin classification by looking for anatomical features that appear to have the
same function as those found on other species.
In order to correctly classify an organism,
scientists use many modern tools.
1.Morphology describes the physical
characteristics of an organism. Typically, this is enough information to place
the organism within a domain and kingdom.
2.DNA and biochemical analysis allow
scientists to test less visible, but distinguishing, characteristics.
3.Comparing embryology allows scientists to
group organisms that share common fetal development.
<span>4.Evolutionary
phylogeny describes the evolutionary relationships between organisms.</span>These
relationships are deduced based on shared traits that may have been passed from
ancestor to new species. Traits
may include physical traits (ex. presence of jaws), or may be genetic traits
(shared genes).
Answer:
their are two electric and body cells which is body building blocks of life which
<span>Without variation, there is no difference between members of a population to be "selected for" in the first place. This is a basic tenet of natural selection. A new trait must arise in order to advance or decrease the fitness of the individual, and hence, its ability to pass on its genes.</span>
Answer:
In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46.
Explanation:
<span>The correct answer would be amoeba. So the amoeba consists of protoplasm and a nucleus. For an amoeba the nucleus is a major organelle, which is located centrally. As such a major organelle it naturally has a huge role, and that is that it controls reproduction (it contains the chromosomes) and many other important functions (including eating and growth).</span>
