Answer:
B. an air-conditioning system.
Explanation:
Refrigeration is defined as a process of cooling a system to lower temperature below the surrounding temperature while the removed heat is rejected at higher temperatures.
Heat pumps use the heat output of the refrigeration process, which may also be designed to be reversible, but are otherwise similar to air conditioning units.
Answer:
B. chemical
Explanation:
Chemical change cannot go back to its original form
Human hair. Human hair as energy because it is living so, it is most likely to give up electrons.
Hey There!
To solve this question remember that 1 mole of ammonia is equal to 17G of ammonia.
Using that, we first multiply 17 by 7 = 24
Then we multiply 7 by .27 = 1.89
Finally, taking those and adding them together gives you the answer...
<u>25.89 grams :)</u>

A polyribosome (or polysome) is a complex of one mRNA molecule and two or more ribosomes that form a polypeptide chain during active translation. Since multiple ribosomes can translate mRNA simultaneously, many polypeptides can be produced simultaneously from a single mRNA.
<h3>Role of all molecular constituents present in a functional polyribosome ;</h3>
1. mRNA: contains the codon
2. tRNA : contains the anticodon for the mRNA
3. Ribosome (large & small subunits): facilitates interaction between mRNA and tRNA
4. Amino acids:
5. Initation Factors: proteins important in the interaction/binding of the small subunit, mRNA, TRNAmet, and the Shine Dalgarno sequence
7. Elongation Factors: bring charged tRNA's to the A site of the ribosome
8. GTP: provides energy
Ribosome recruitment in eukaryotes occurs when the eukaryotic initiation factor e1F4F and poly(A) binding protein (PABP) recognize 5′-capped mRNAs and recruit the 43S ribosome complex to this site. increase. In addition, the Kozak consensus sequence ACCAUGG is also required for translation initiation. Therefore, at first glance, it seems unlikely that overlapping sequences will be translated.
