<em>A placental mammal develops before its body systems can function independently;</em>
A. Inside it's mothers body
<u>Mammals don't come from eggs, and the term placental mammal means it has a placenta. It comes out when our mothers deliver. A marsupial mammal forms in a pouch, so the answer is inside it's mothers body </u>
Wegener supported his theory by means of demonstrating the Pangaea and geological similarities among continents. South America and Africa contain fossils of animals observed simplest on the ones two continents, with corresponding geographic levels.
Pangaea Wegener was satisfied that every one of Earth's continents have been as soon as a part of a good-sized, single landmass referred to as Pangaea. Wegener, educated as an astronomer, used biology, botany, and geology to describe Pangaea and continental drift.
The rock formations of eastern North the USA, Western Europe, and northwestern Africa were later found to have a not unusual starting place, and they overlapped in time with the presence of Gondwanaland. together, those discoveries supported the life of Pangea.
Wegener showed that positive styles of rocks on the continents would match with others in some other continents. What did Wegener realize approximately the oldest rocks on the African and South American continents? That they had been connected collectively whilst the continents were arranged to shape Pangaea.J

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.
