Explanation:

Plankton avoid sinking by increasing their surface area and decreasing their density. Spines slow down sinking by adding surface area without increasing density. Defense against predation would be to sing below. Not the opposite.

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

kaheart [24]

I think the cause of the illness is Rota-virus. Its a contagious virus that can cause gastroenteritis(inflammation of the stomach and intestines|). Symptoms include severe watery diarrhea, vomiting, fever and abdominal pains. Infants and young children are most likely to get rota virus disease, they become severely dehydrated and can even die.
