Why is ethnicity important to geographers?
Ethnicity, it’s characters derive from the distinctive features of particular places on Earth. Ethnicity is especially important to geographers because in the face of globalization trends in culture & economy, ethnicity stands as the strongest bulwark for the preservation of local diversity.

What is ethnicity in human geography?
Ethnicity. Definition: Identity with a group of people that share distinct physical and mental traits as a product of common heredity and cultural traditions.
How does ethnicity cause devolution?
Ethnic nationalist political parties may compete for political power or attempt to gain control of territory. Irredentism, as a country may attempt to annex or regain territory in a neighboring state inhabited by people who have ethnic ties back that country.
What is an example of race AP Human Geography?
Ethnicity identifies groups w/ distinct ancestry and cultural traditions, such as Hispanic-Americans, African-Americans, Chinese-Americans, or Polish-Americans. Race distinguishes blacks and other persons of color from whites.
How does ethnicity difference from race AP Human Geography?
Ethnicity describes cultural identity while nationality describes political ties and ideas about voting, passports, and civic duties. American is a nationality, Hispanic-American or African-American are ethnicities, and race is the genetic heritage with skin color being the most visible trait.
Is race a geographical?
Traditionally, subspecies are seen as geographically isolated and genetically differentiated populations. Studies of human genetic variation show that human populations are not geographically isolated, and their genetic differences are far smaller than those among comparable subspecies.
Should I use race or ethnicity?
“Race” is usually associated with biology and linked with physical characteristics such as skin color or hair texture. “Ethnicity” is linked with cultural expression and identification. However, both are social constructs used to categorize and characterize seemingly distinct populations.
What is the Colour of DNA?
Figure 2: The four nitrogenous bases that compose DNA nucleotides are shown in bright colors: adenine (A, green), thymine (T, red), cytosine (C, orange), and guanine (G, blue).
What does DNA look like in real life?
A. Deoxyribonucleic acid extracted from cells has been variously described as looking like strands of mucus; limp, thin, white noodles; or a network of delicate, limp fibers. Under a microscope, the familiar double-helix molecule of DNA can be seen.
What are the four bases of DNA?
Adenine, thymine, cytosine and guanine are the four nucleotides found in DNA.
What sugar is found in DNA?
deoxyribose
Where is the nitrogenous base in DNA?
Nitrogenous bases present in the DNA can be grouped into two categories: purines (Adenine (A) and Guanine (G)), and pyrimidine (Cytosine (C) and Thymine (T)). These nitrogenous bases are attached to C1′ of deoxyribose through a glycosidic bond.
Where is the location of DNA?
nucleus
What is the five-carbon sugar found in DNA?
Ribose, also called D-ribose, five-carbon sugar found in RNA (ribonucleic acid), where it alternates with phosphate groups to form the “backbone” of the RNA polymer and binds to nitrogenous bases.
What is the difference between sugar in DNA and RNA?
There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine. …
What are the 6 carbon sugars?
The main monosaccharides are the hexoses (simple sugars in which the molecules contain six carbon atoms)—these include glucose (known also as dextrose), fructose1 (commonly called levulose), galactose, and mannose (Eliasson, 2016). All of which are naturally found in fruit juices.
What makes up the rungs of DNA?
Other combinations of the atoms form the four bases: thymine (T), adenine (A), cytosine (C), and guanine (G). These bases are the rungs of the DNA ladder. (It takes two bases to form a rung — one for each side of the ladder.)
Which two molecules are from the side backbone of the DNA ladder?
Phosphate Backbone A phosphate backbone is the portion of the DNA double helix that provides structural support to the molecule. DNA consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups.
What is the twisted ladder shape of DNA called?
Double Helix Double helix is the description of the structure of a DNA molecule. A DNA molecule consists of two strands that wind around each other like a twisted ladder.
What are the elements in DNA?
DNA has three types of chemical component: phosphate, a sugar called deoxyribose, and four nitrogenous bases—adenine, guanine, cytosine, and thymine.
Is sulfur a DNA?
They also knew that proteins contain sulfur atoms but no phosphorus, while DNA contains a great deal of phosphorus and no sulfur.
What is a shape of DNA?
The double helix is a description of the molecular shape of a double-stranded DNA molecule. In 1953, Francis Crick and James Watson first described the molecular structure of DNA, which they called a “double helix,” in the journal Nature.
What is DNA structure and function?
The genetic information stored in an organism’s DNA contains the instructions for all the proteins the organism will ever synthesize. In eucaryotes, DNA is contained in the cell nucleus. A DNA Molecule Consists of Two Complementary Chains of Nucleotides. The Structure of DNA Provides a Mechanism for Heredity.
