Answer:
The correct answer is- B) Cell walls are made primarily of peptidoglycan
Explanation:
There is a difference between the cell wall of bacteria, archaea, and eukarya. The cell wall of bacteria is primarily made up of peptidoglycan which contains two sugar N-acetylglucosamine and N-acetylmuramic acid while archaea contain two N-acetyltalosaminuronic acid (NAT) in place of N-acetylmuramic acid which is called pseudo-peptidoglycan.
Eukaryotic cell wall is also different from archaeal and bacterial cell wall and animals in eukaryotes do not have a cell wall. Therefore cell wall made up primarily of peptidoglycan will allow you to classify the organism as belonging to Bacteria but not Archaea or Eukarya.
Answer:
antigen-MHC protein complexes
Explanation:
Helper T-cells recognise antigens that are complexed with MHC proteins and interact with target cells. Antibodies can be produced against a single antigen in a variety of ways. Toxic shock syndrome is a relatively mild condition that resembles other minor allergy responses. Antigen-presenting cells break down superantigens.

Yes I believe the answer is D it is th only logical one.
<span>The branch of
anatomy that focuses on body structures that are visible to the naked eye is
called gross anatomy. It is only concern with macroscopic details and therefore
do not need any aid of instrument. Gross anatomy is used to study dead bodies
that uses two approaches. The systemic approach, studied the different system
of the body while in regional approach, human body is studied in different regions. </span>
