Answer:
Answer of question 1 :
Explanation:
Let x be the legs of ducks
And y be the legs of cows
According to the question,
2x + 4y = 52...…..(i) ( as ducks ahs two legs and as cows has 4 legs)
As he has 21 animals in total so,
x + y = 21...…..(ii)
We have make the equation. We will solve them by eliminatory method or substitution method. Here, I'll go for substitution method.
From equation (ii)
x = 21 - y....…..(iii)
Putting the value of x in equation (i),
2x + 4y = 52
2( 21 - y ) + 4y = 52
42 - 2y + 4y = 52
2y = 52 - 42
y = 10/2
y = 5 ( He has 2 cows)
putting the value of y in equation (ii)
x + y = 21
x + 5 = 21
x = 21 -5
x = 16 ( He has 16 ducks)
Ok yeaa
sure we can do it

<h3>How do you get the tRNA anticodon?</h3>
An anticodon is known to be seen at a given end of a transfer RNA (tRNA) molecule. In protein synthesis, when an amino acid is added to the growing protein, a tRNAis said to be produced as the base pairs along with its complementary sequence that is seen on the mRNA strand.
Conclusively, Note that codon is regarded as the a follow up of three nucleotides on mRNA, that encodes for a particular amino acid at translation.
