What is the mystery element? is this a metal, nonmetal, or metalloid?
kiruha [24]

This is a metal!

I believe this is a metal because non-metal can be cut out instantly as this element shown has a metallic luster. Metalloids can be removed as they are worse at the conduction of electricty than metals, and all of the other properties listed are properties held by metals.

(Yes this is just my old answer but only because it is really the same reasoning)

Hope this helps, if not, comment below please!!!

1. Describe the structure and function of each of the three types of RNA.
Ket [755]

Answer:

1.

mRNA - Messenger RNA: Encodes amino acid sequence of a polypeptide.

tRNA - Transfer RNA: Brings amino acids to ribosomes during translation.

rRNA - Ribosomal RNA: With ribosomal proteins, makes up the ribosomes, the organelles that translate the mRNA.

2.

Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis. Transcription takes place in two broad steps. First, pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes.

3.

During translation, which is the second major step in gene expression, the mRNA is "read" according to the genetic code, which relates the DNA sequence to the amino acid sequence in proteins. Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid (hence, it is a triplet code). The mRNA sequence is thus used as a template to assemble—in order—the chain of amino acids that form a protein.

<h3>What is protein hydrolysis?</h3>


Protein hydrolysis is a complicated process that comprises a series of enzymatic processes, each with a unique kinetic response for numerous substrates.

Two enzymes that aid the digestion of protein in the body are;

  • Pepsin; and
  • Trypsin.
