Answer:
The correct answer is - false.
Explanation:
Penicillin-binding protein 2a or PBPs are protein produced by bacteria that binds with the β-lactam antibiotics such as penicillin. They play role in the cell wall synthesis of bacteria by producing peptidoglycan by catalyzing the reaction.
β-Lactam antibiotics bind with the PBPs and cause the disruption to peptidoglycan cross-linking in the biosynthesis of the cell wall and ultimately lysis of bacteria takes place and cell death.
Answer:
AT and GC are DNA base pairing

A)
<span><u>proteins</u>
</span><span>Cell membranes contain membrane proteins that allows all the interaction that occurs within the cell. It makes the cell membrane selectively permeable because of its characteristics as being fluid or its fluidity which means to say that they can move freely within the lipid bilayer. The membrane proteins can also be stored in the lipid bilayer together with the enzymes. It cannot be denied that membrane proteins have a lot of functions based on its type. They can be integral proteins, peripheral proteins and lipid bound proteins. </span>
The body's first line of defense is the mucous membranes
Answer:
Symbiosis and decomposers.
Explanation:
The ants feed on both plants and insects so we can say that ants are omnivorous. They make a symbiotic relationship of mutualism with fungi such as mold which helps the ants to breakdown the cellulose of plants whereas plants provide habitat to fungi. The bacteria feeds on the dead body of ants and release nutrients by performing the function of decomposition so bacteria acts as decomposer so in that way these four organisms interact with each other.
