Answer the following questions (they are in order): What is Taxonomy?
The branch of science concerned with classification, especially of organisms.

If we go back far enough every living thing is related to every living thing, meaning we all have what?
A common ancestor.

Who is the Swedish scientist that developed this classification system?
Carl Linnaeus.
I NEED THE ONES BELOW
Although taxonomy has come a long way since Linnaeus, we are still using the same taxa groups to classify. List these groups

We are also using binomial nomenclature, the use of a 2 part name for every species. What 2 names do we use to name an organism?
Genus and Species

Now that we have new technology and can classify using genetic analysis and structure, we have stuck a new taxa above Linnaeus’s kingdom. What is this more broad taxa called?

What are the domains 3 we have? Under the domain Eukarya, we have 4 kingdoms. List the 4 Eukaryotic Kingdoms.

The fungus kingdom includes organisms like . . .

Fungus has cell walls like plants, but instead of being made of cellulose, they are made of , which is the same material in the exoskeleton of a beetle.

Fungus are like animals and break down their food and reabsorb the nutrients.

answer; //the above statement is (false);

yay can i have brainliest

the african cheetah.

this species has a relatively low level of genetic

variation because the population was reduced to a small size approxi-

mately 10,000 to 12,000 years ago.

until   now,   we   have   primarily   focused   our   attention   on   genes  

within   individuals   and   their   related   family   members.   in   this  

chapter   and   chapters   25   and   26   ,   we   turn   to   the   study   of   genes   in  

a   population   or   species.   the   field   of

population   genetics

  is   con-

cerned   with   changes   in   genetic   variation   within   a   group   of   indi-

viduals   over   time.   population   geneticists   want   to   know   the   extent  

of   genetic   variation   within   populations,   why   it   exists,   and   how   it  

changes   over   the   course   of   many   generations.   the   field   of   popu-

lation   genetics   emerged   as   a   branch   of   genetics   in   the   1920s   and  

1930s.   its   mathematical   foundations   were   developed   by   theoreti-

cians   who   extended   the   principles   of   gregor   mendel   and   charles  

darwin   by   deriving   formulas   to   explain   the   occurrence   of   geno-

types   within   populations.   these   foundations   can   be   largely   attrib-

uted to three scientists: sir ronald fisher, sewall wright, and j. b. s.

haldane.   as   we   will   see,   support   for   their   mathematical   theories  

was provided by several researchers who analyzed the genetic com-

position   of   natural   and   experimental   populations.   more   recently,  

population   geneticists   have   used   techniques   to   probe   genetic  

variation   at   the   molecular   level.   in   addition,   staggering   advances  

in   computer   technology   have   aided   population   geneticists   in   the  

analysis   of   their   genetic   theories   and   data.   in   this   chapter,   we   will  

explore   the   genetic   variation   that   occurs   in   populations   and   con-

sider   the   reasons   why   the   genetic   composition   of   populations   may  

change over the course of several generations
