Bibliography is essential in determining its content. I hope this helped
A food web does not represent all the links in an actual ecosystem.
Explanation:
A food web is also called food cycle. It is understood by the natural interconnection of chain and their graphical representation. The concept is given by Charles Elton. He mentioned about the concept of food cycles in Animal Ecology but later this food cycle is replaced by food web.
Food web are limited representation of eco system. Ecologists can keep together all life forms broadly into one of the two categories which is called tropic levels. These two categories are autotrophs and heterotrophs
Hey there!
the answer to ur question is : 1,3, and 4
Hopes this Helps u! :D
Answer:
Explanation:
B) The pentose in the hairpin adopts only the C-3\' endo pucker conformation.
C) The hairpin adopts a right-handed helix with a diameter of 26 Å .
D) The hairpin contains G:C, A:U, and sometimes G:U base pairs.
DNA and RNA are both nucleic acids. Aside the structural difference of DNA being double stranded and RNA being single stranded, in DNA, the nucleotide bases adenine (A) is paired with thymine (T); while cytosine (C) is paired with guanine (G); howerver in RNA, thymine is replaced with uracil.; thus in RNA, the base pairs are - A:U and G:C
RNA however sometimes take on a dynamic structure, called the wobble case pair where guanine and uracil pair - G:U.
The diameter of RNA is 26 Å, while that of DNA is is 20 Å
The ribose in RNA with a helical structure has a C3’ endo conformation.
