Answer:
The correct answer is the neurotoxin known as tetanospasmin toxin.
Explanation:
Tetanus is a disease caused by a bacteria known as clostridium. The bacteria are found in soil, manure, dust, and saliva. It can enter the host body by a cut or rusted or dusty nail or burn. It causes muscle spasm or jaw locking or bone locking.
It releases the neurotoxin that is tetanospasmin toxin that inhibits the secretion of γ-aminobutyric acid (GABA) and results in a variety of symptoms associated with tetanus.
Thus, the correct answer is the neurotoxin known as tetanospasmin toxin.

Answer:
Transporters are the integral membrane proteins that serve to move the substances across the membrane.
Explanation:
Transporters are the membrane proteins that serve to move specific ions or molecules across the lipid bilayer. These are the integral membrane proteins. Transporters include carriers, channels, pumps, etc. Channels are the integral membrane proteins that serve to provide a pathway for transport of charged and/or polar substances that otherwise can not cross the non-polar core of the lipid bilayer.
Pumps are involved in the active transport of substances against the concentration gradient and use the energy of ATP hydrolysis. Some of the examples of transporters are voltage-gated ion channels, GLUT1 glucose transporter, F₀F₁ ATPase proton pump, etc.
Answer:
Fungi cause decay by releasing enzymes onto the dead animal or plant. These break down complex compounds into simple soluble ones that can be absorbed by decomposers. Organisms that feed on dead material in this way are called saprophytes.
