Julio is studying the evolutionary history of desert cottontail rabbits, sea otters, and grizzly bears. All three species share
krek1111 [17]

Answer:

One way that Julio can explain such differences is that their environments are very similar and therefore the traits that were best suited for their survival were passed on from generation to generation. The traits that each species developed differently would have been due to their diet. Each species has a different diet and certain traits allow them to more easily hunt/gather the food that they need to survive. For example, grizzly bears and sea otters both eat fish as their main diet and therefore have both developed canine teeth, while rabbit teeth are different due to them only eating vegetation.

Which type of RNA functions as a carrier of the genetic code?
gayaneshka [121]

All forms of RNA are intermediate molecules that are fabricated within DNA to perform cellular functions.

mRNA - messenger RNA carries selected portions of DNA used to fabricate polypeptides used to fabricate amino acids for protein.

tRNA - transfer RNA is comprised of select genetic code and transfers amino acids to ribosomes for assembly

rRNA - ribosomal RNA is comprised of select genetic code and makes the ribosomes

RNA is highly mutatable, highly reactive, non-reproductive, and highly specialized metabolically, and consequently totally unsuitable for consideration of any pre-DNA senario being posited for the origin of life.
