Answer:

The correct answer is b.  an amino acid

Explanation:

A tRNA is called adaptor RNA which have cloverleaf-like secondary structures. These structures contain stems and loops which make up the acceptor arm, anticodon stem and loop, D- stem and loop, and T- stem and loop.

Acceptor arm contains seven base pairs and four single stranded nucleotide which include conserved CCA sequence. The function of acceptor arm is attach amino acids require for  protein synthesis.

The anticodon loop gives information to acceptor to attach a specific amino acid according to the sequence present in mRNA. The first amino acid which attaches to acceptor arm is methionine.

Thus, the correct answer is b. an amino acid.

sergiy2304 [10]

Answer:

protected; increase

Explanation:

Ozone is composed of trioxygen which is highly reactive gas compared to dioxygen. Ozone layer is present in stratosphere and troposphere and protect the humans from ultraviolet radiations but it may be toxic if inhaled. Ozone can be broken down into molecular oxygen by chlorine and bromine atoms.

A hole was discovered in ozone layer in 1982 and scientist believed that it could be dangerous for human health. The compounds involved in depletion of ozone are mainly Chlorofluorocarbons (CFS) and (HFCS). Then a global agreement was signed in 1987 which leads to prohibition of use of all chemicals that are involved in depletion of ozone layer. The problem of ozone depletion is solved by the agreement and ozone hole started to recover it from 2000.

But recent reports showed that the alternative chemicals used to protect the depletion of ozone layer began to trap the heat inside the earth like greenhouse effect. Now scientists are in search of chemical that can prevent both ozone depletion as well as global warming.
