<span>Certainly. Every organism has a variety of different characteristics. One person writing a key might choose to use different characteristics than another person would use.
For example: Here's a key for separating fish, snake, frog and mouse
1.
A. Has scales on its skin ... 2
B. Has no scales on its skin ... 3
2.
A. Breathes with gills - fish
B. Breathes with lungs - snake
3.
A. Has hair or fur - mouse
B. Has no hair or fur - frog
Here's a different key for the same four animals:
1.
A. Has four legs ... 2
B. Does not have 4 legs ... 3
2.
A. is warm-blooded - mouse
B. is cold-blooded - frog
3.
A. has fins - fish

<span><span>As for the responder, science study as much as it can
process. Though there are certain principles, theories and laws needed to
determine one is truly science. It needs to undergo the scientific method to
analyze and gather evidential data and in addition this study should be
replicable in the process. Replicable is one strong characteristic of a study
that can intensify the reliability and validity of the field. And what science
doesn’t study is not until the principles apply to the aforementioned
statement. Science can study and wants to understand everything or in as much
as the broader scope of each phenomenon, it’s some concepts that are just very
hard to gather data, and studies like the metaphysical and paranormal that can’t
be repeated. These limitations inhibit scientists to draw data that is reliable
and valid, thus, science. </span> </span>
MRNA is the RNA that assists in Messaging the DNAs instructions to the ribosomes (sites of protein synthesis). tRNA helps to transfer the necessary amino acids to the ribosomes. In short, mRNA tells the ribosomes what amino acids to use and in what order. tRNA “retrieves” those and bring later them to the ribosomes.
Answer: True.
I Really Hope This Helped You! :)
