Skin is a barrier that serves as one of the body's first lines of defense against harmful microbes. Specialized immune cells within skin tissue help to fight invading organisms. Past work by an NIH research team showed that commensals can help the body's immune cells fight disease-causing microbes.
Hope this helps you!

Breeding horses. People want prized racehorses to mate with their females so they can maybe have fast prize winning horses as well. People also use artificial selection in choosing fast horses to make fast colts that can later on race. So they want the best qualities in the colts so they mate the best horses.
Hope this helps :)
Answer:
the cooler air is H, and the hotter air is L
Explanation: Since the cooler air is less dense it has lower pressure, which is why it sinks. the hotter air becomes less dense because the molecules are faster and spread out hence it has less pressure and rises
Answer:2.)One start codon and one stop codon are used for its synthesis.
3.)The piece of genetic code used for its production contains 11 codons.
Explanation: A codon is a nucleotide sequence on the mRNA that is made up of three nucleotides molecules. A codon is a nucleotide sequence that codes for a specific amino acid. Every amino acid is coded for by at least one codon. Some amino acids are coded for by more than one codon.
During protein synthesis, every protein is synthesized using one start codon and one stop codon. A start codon signals the beginning of translation while the stop codon signals the end of translation. The start codon codes for methionine while the stop codon codes for no amino acid. Therefore, a protein whose genetic sequence has 11 codons is synthesized using a piece of genetic code containing 11 codons.
Amino acids are the monomers of proteins :)
