How do artificial and natural selection contribute to biological diversity?
selection processes always reduce diversity. processes modifying genes increase diversity.
What are two ways in which RNA structure differs from DNA structure?
Chemically RNA and DNA only differ by a single oxygen atom in each nucleotide. Specifically the sugar group in an RNA nucleotide is the sugar ribose, wherease the sugar group in DNA is deoxyribose. Wikipedia has a nice image showing this here: http://en.wikipedia.org/wiki/File:Nucleotides_1.svg Structurally RNA and DNA are also different. DNA exists almost exclusively in a double stranded helix. RNA is typically thought of a single chain that has a far more chaotic structure with the RNA folding back onto itself creating small helical regions where possible. DNA nucleotides contain a different sugar than RNA nucleotides.
What is the importance of the ratios A to T and G to C to the structure of DNA?
The ratios A to T and G to C are very important to the structure of DNA. A or Adenie only bonds with T or Thymine so there are almost always equal numbers in the structure. This is also true with C or cytosine and G or guanine.
A structure that contains at least two different types of tissue functioning together for a common purpose?
Organ, I go 2 RAMS and this was on our Hmk of course it is its on mine 2! thx for the answer! lol its a cross word for science class! ugh i hate science! I've gotten every answer for it on here! lol clearly other kids have asked it cause there is always links on google with the same exact ? so its cool! lol On mine to i go to NMBMS! I hate this
Why do diploids always contain an even number of chromosomes?
The diploid number is always even because it contains two complete sets of chromosomes. Since there is two sets you split the diploid number in half. Two times any number is always even.
The default base is always required in the switch selection structure?
yes,true
How does natural selection contribute to biological evolution?
Selection is not always of the most fit to survive.
Does natural selection occur in the world today?
Yes, natural selection is always occurring.
What does the structure of DNA contain?
DNA contains 4 nitrogenous bases that pair with each other. Thymine always pairs with Adenine, and Cytosine always bonds with Guanine. DNA also contains the sugar deoxyribose.
What is a sentence that has the word structure in it?
There is always a structure to every complete sentence.What is the structure of a paragraph?
What is the title of the selection?
A, Pepper Always Adds Flavor,
What always contains a?
The alphabet
The default base is always required in switch selection structure true or false?
False. The Default section of a switch case section is not mandatory. the programmer can choose to have it if he wants to implement a default functionality in cases where none of the cases match the conditions.

Does Data always contains facts true or false?
Data always contains information, but not necessarily facts. Data can be completely made up.
Function always follows structure is referred to as the principle of what?
The principle of complementarity of structure and function.
Why is it the Darwin theory natural selection is nice?
Nice? The theory of evolution by natural selection is the best and best supported explanation for the fact of evolution we have, but it just is and a word such as " nice " would not always fit theory. Google Ichneumon wasp to see that natural selection is not always " nice. "
