The right answer is B. peptidoglycans.

Peptidoglycan (or murine, or mucocomplex, or mucopeptide) is a component of the bacterial wall maintaining the shape of cells and providing mechanical protection against osmotic pressure. It forms a thin layer in Gram-negative bacteria and a thick layer in Gram-positive bacteria.

It consists of a carbohydrate moiety (= polysaccharide) and a peptide moiety. The polysaccharide is a glycosaminopeptide polymer wherein N-acetylglucosamine (NAG) and N-acetyl-muramic acid (NAM) are linked by beta (1-4) osidic bonds. This bond can be cut off by lysozyme. NAM is a specific compound of bacterial walls. Two polysaccharides are linked by peptide bridges at the level of the NAM, formed by different amino acids: D-alanine, L-alanine, glutamic acid, L-lysine, diaminopimelic acid (lysine analog). Amino acids D are specific for the bacterial wall, they are never found elsewhere.

san4es73 [151]

Answer:

In a population, a specific gene has two alleles, 'A' and 'a.' Individuals with

genotype 'aa' die in early childhood. Individuals with genotype 'Aa' have a

higher rate of surviving and reproducing than individuals with genotype 'AA.'

This phenomenon is called survival of the fittest, Darwins law which entails the fittest organisms survives while the ones that could not would go into extinction

Ethan has been eating salads without first washing the lettuce. He risks ingesting which type of bacteria?
vodka [1.7K]

Ethan has been eating salads without first washing the lettuce. He risks ingesting E-Coli and Salmonella bacteria.

  • You could inhale dangerous bacteria from the soil or pesticides used on the produce in the fields if you eat unwashed produce. Furthermore, it's possible that you'll consume bugs that were collected with the produce.
  • Animal-based foods like meat, poultry, eggs, dairy products, and shellfish are frequently the cause of food poisoning in humans.
  • Fruits, vegetables, and other raw foods, however, can potentially be polluted and sicken people if they aren't rinsed beforehand.
  • Fruits and vegetables that are the safest are cooked; those that are the next-safest are washed.
  • Prevent eating unwashed fresh food. Fresh produce has many health benefits, but eating raw fruits and vegetables occasionally puts you at risk for food poisoning from pathogens including Salmonella, E. coli, and Listeria.

seropon [69]

Answer:

This question is incomplete

Explanation:

This question is incomplete but the completed question can be found in the attachment below.

During protein synthesis, a sequence of three mRNA nucleotides (called codons) correspond to specific amino acids. From the question, the change in guanosine nucleotides will change the sequence as follow

DNA:   T--A--C--A--A--C--T--A--C--T--T--C--T--T--T--C--T--T--A--A--A

mRNA:             A--U--G|-U--U--G|-A--U--G|-A--A--G|-A--A--A|-G--A--A|-U--U--U

Amino Acids:       met --     leu   --   met   --  lys    --   lys    --    Glu   --  Phe

The new amino acid sequence is represented above from the new DNA sequence.
