Some common inherited characteristics
<span>Ribonucleic acid (RNA) occurs
primarily as single strands, often giving rise to single polynucleotide
structures. RNA is a polymeric molecule
that is responsible for the regulation, coding, decoding and expression of
genes. Each nucleotide has a ribose sugar attached to the carbon, a base that
is composed of purines and pyrimidines, a negatively charge phosphate groups
and a hydroxyl group which causes helix to mostly adopt the A-form geometry.</span>
Answer: What makes a marsupial, a marsupial? A discussion on the historical biogeography and biological evolution of marsupial mammals. Dr. Robert Voss is a professor at Richard Gilder Graduate School and the American Museum of Natural History. His primary research interests are the evolution of marsupials and the systematics and biogeography of other Neotropical mammals that inhabit moist-forest habitats in Amazonia and the Andes.
What anatomical characteristics distinguish marsupial mammals from placental?
Living marsupials and placentals can be distinguished by a number of anatomical features, including structural differences in their ear regions, teeth, postcranial skeletons, reproductive tracts, and brains. Most people think of pouches when they think about marsupials, but not all marsupials have pouches.
When did these two subclasses of mammals separate from their common ancestor? What do we know about that common ancestor?
The lineages that gave rise to living marsupials and placentals are recognizably distinct in the fossil record as far back as the Early Cretaceous (about 125 million years ago), so the most recent common ancestor of these groups must have lived even earlier. How much earlier is controversial, with some estimates suggesting a date of almost 150 million years (in the Late Jurassic). We don’t know anything about that ancestor for certain, but we assume that it was not unlike the earliest known marsupials and placentals: probably a small climbing (arboreal or semiarboreal) mammal, perhaps superficially resembling living opossums or tree shrews. Because the earliest known marsupial and placental fossils are from China, most paleontologists assume that their most recent common ancestor lived somewhere in eastern Asia.
What is convergent evolution and what are some examples of convergent evolution between marsupial and placental mammals?
Convergent evolution is the appearance of similar traits in distantly related lineages. Examples of convergent evolution between placentals and marsupials are the extinct Tasmanian “wolf” (a very wolflike marsupial), marsupial “moles” (living molelike marsupials that burrow in the sandy deserts of Australia), and kangaroo rats (North American rodents that hop on their hind legs like kangaroos).
Explanation:
Answer:
Allowing the birds to avoid many types of predators.
Answer:
Option C, 
Explanation:
The diploid number of chromosomes are represented as 
.
Here the somatic chromosome number is 
which can be represented in the "" format with N being equal to 
.
Now, as we know that the total number of chromosomal combination with chromosome number being
is equal to
Substituting the given values in above equation, we get -
Therefore, total of different combinations of centro-meres could be produced during meiosis.
Hence, option C is correct
