Data shows results of an experiment which was added to each peptide to culture the TRAP. Mutants of S. aureus and culture of the Agr. mutant of s. aureus.
Peptide 1 and three blocks Agr pathway
Peptide 2 blocks TRAP pathway
This is because the mutants are already blocked for one of the pathways.
Therefore it gives way to determine which pathway each peptide act on.
The best answer is C.
The outermost covering of plant cells is called the cell wall. It is made up cellulose, is rigid and can be seen under a light microscope. It is absent in animal cells.
The outermost covering in animal cells is the cell membrane. It is made up of lipids, proteins, and small amounts of carbohydrates. It is a thin and delicate structure that can only be seen under an electron microscope.
Plant cells have both cell wall and cell membrane
The answer is C) the sun. “The sun is the major source of energy for organisms and the ecosystems which they are part of” & “Light is the PRIMARY source of energy to almost all ecosystems”
