Which of the inner transition metals is critical to the nuclear power industry.
Rom4ik [11]

Answer:

<u>Uranium</u> is the  inner transition metals is critical to the nuclear power industry.

Explanation:

Uranium is a common transition metal found in rocks and is used for nuclear fission reactions. In a nuclear fission reaction, a neutron atom is hit on a uranium atom. As a result, the uranium atoms breaks down releasing huge amounts of energy. Also, more neutrons are released by the breakdown and hence the this neutron hits other uranium atoms and the cycle continues. The most active radioisotope of uranium being used in nuclear fission reactions is U-235.

What is true about translation? Choose ALL that apply.
Licemer1 [7]

<u>In the process of translation, the statement stands correct and applies are as follows:</u>

  • The ribosome has two sub-units that work together.
  • Amino acids are joined by peptide bonds.
  • Each tRNA brings in exactly one amino acid that corresponds to the anti-codon.
  • The order of the amino acids is determined by the mRNA which is transcribed from DNA.

Answer: Options A, B, C, and E

<u>Explanation:</u>

In the process of translation, ribosomes are the structural unit where the translation is being performed and it has the two sub-units which enact together the translational process.

Any two amino acids are bonded together by peptide bond and tRNA brings one amino acid at a time which corresponds to the anti codon. The order of amino acids is determined by mRNA transcribed from the DNA, and not from the ribosome. Thereby, all given options are correct except the option D.
