One of the ways that food can be preserved is by heavily salting it so that bacteria cannot live upon the food. What causes the

Marina CMI [18]

Answer:

Dehydration

Explanation:

What causes bacteria to die in an extremely salty environment is dehydration due to the loss of osmotic balance in their cells.

Water molecules would normally move from the region of high water potential or low solute concentration to the region of low water potential or high solute concentration through a biologically permeable membrane.

<em>An extremely salty environment would be hypertonic to the cells of bacteria and the cell walls of bacteria act as biologically permeable membranes. Hence, the bacteria cells lose water due to the osmotic movement of water from their cells to the surrounding salty environment. </em>

DNA is transcribed to messenger RNA (mRNA), and the mRNA is translated to proteins on the ribosomes. A sequence of three nucleot

Maru [420]

Answer:

start codon - AUG

in-sequence amino acid - AAA, UGC, AUC, CAC, GCA, ACU

stop codon - UAA, UAG, UGA

Explanation:

From the amino acid chart, the start codon is represented by the codon AUG which also code for the amino acid methionine. There are three stop codons including UAA, UAG, and UGA. The stop codons signal the end of the translation process of the mRNA. Every other codon within the mRNA chain codes for different amino acids except methionine.

Hence, using the attached amino acid chart:

start codon - AUG

in-sequence amino acid - AAA, UGC, AUC, CAC, GCA, ACU

stop codon - UAA, UAG, UGA
