Answer:
Nine
Explanation:
These are called carrier proteins, and they have what it is called: solute-binding sites, that when saturated, they are considered "full".
Each different amino acid needs a separate carrier protein to move it across the plasma membrane, so that's 3, then the four different sugars need separate carriers as well, we add 4 more then, we have 7 so far, finally the 2 different ions use 2 more, plus the other 7, totals 9.
Well, humans have talents. Whether those talents are god given is up for debate. I'd argue those talents are a result of millions of years of evolution and natural selection as proven by Charles Darwin, not given by an unproven deity, but I don't know what school year you are in so you may not have escaped the years where religion is forced upon you :P
Anyway, if you're being asked this question, what do <em>you </em>like doing? I'd say my talent lies in science, as I was the top performing physicist throughout my gcse years, and I love the subject. In my opinion what you do best is what you love doing most, as if you have a passion for something it will almost always be your best talent. I can't answer that question for you.
Sharing this talent to others is basically teaching and also spreading your passion for your talent to others. They probably won't ever be as good as you because they will have their own talents and passions, but you can give them an insight into it by teaching them what you know and encouraging them to invest some time into it.

Answer:
C) binding to mRNAs and degrading them or blocking their translation
Explanation:
<u>miRNAs:</u>
miRNAs is the abbreviation of MicroRNAs. These are the small noncoding RNAs of ∼22 nucleotides which can not code for peptides. miRNAs are responsible for gene expression regulation at the level of post transcription. They can do so by forming complementary base pairing with target mRNA and inhibiting their translation.
They silenced mRNA by the following processes:
(1) Cleavage of the mRNA strand into pieces,
(2) stopping mRNA from translation into proteins by ribosomes.
(3) Shortening of mRNA poly(A) tail and destabilizing it.
