Answer: Option B

Explanation:

If a statement is given which states that an object is 3000 light years away then it states that the object that we can see now by our eyes must have arrived 3000 years before to reach our eyes.

Light years is generally used to measure the distance between the earth and heavenly bodies. It takes light years for any object's light to reach the earth.

It is generally used for very long distances that cannot be converted into kilometers or meters.

What advantage is there in having the special sensory organs confined to the head region?

Dmitriy789 [7]

The answer to this question would be: rapid impulse transmission.

By having organ near the head, the brain can process the information faster because the length of the nerve that carries the impulse from organ would be much shorter. The nerve also at lower risk of damage since it was shorter.
But it makes the head very important and damage to the head can cause much more problem than any part of the body.

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
