Answer:

um you don't have the answer to choose from so I looked up on the web and its says ( migrants are more prepared to take on low-paid low-skilled jobs - helps to reduce any labor shortages) I'm pretty sure this didn't help but I hope it did

MAVERICK [17]

Answer:

Run off of animal/plant waste

Explanation:

The run off of animal/plant waste occurs in 3 layers:

upper layer: the terrestrial chamber, the decomposition chamber, and the aquatic chamber.

The terrestrial layer represents the land habitat including plants and insects whereby waste are moved into the  

The decomposition layer much like a compost pile where it decomposes and then move into

The aquatic layer much like a mini freshwater habitat for aquatic plants and even small fish, it serves as food sources for them

During translation, nucleotide base triplets (codons) in mRNA are read in sequence in the 5’ → 3’ direction along the mRNA. Amin
Paladinen [302]

Answer:

The question is incomplete, it lacks the mRNA sequence. The sequence is as follows:

5′−AUGGCAAGAAAA−3′

The answer is Met-Ala-Arg-Lys

Explanation:

Gene expression in living organisms involves the process of transcription and translation. Transcription is the synthesis of a complementary strand of mRNA from a DNA template while translation involves using the transcibed mRNA as a template to synthesize amino acid sequence (proteins).

In the RIBOSOME, where the synthesis of protein occurs, the mRNA nuceleotide sequence is read in a group of three nucleotides called CODON. Each codon specifies a particular amino acid. The collection of all codons is the genetic code. Hence, for a specific mRNA sequence that reads 5′−AUGGCAAGAAAA−3′. The nucleotides will be read three at a time starting with AUG which is a codon that encodes METHIONINE.

Next, GCA is a codon that encodes ALANINE

Next, AGA is a codon that encodes ARGININE

Finally, AAA is a codon that encodes LYSINE.

Hence, the amino acid sequence using the above mRNA sequence, will read: Met-Ala-Arg-Lys
