Fungi do not make their own food. The answer is B.
Answer: The action of a neurotransmitter at the postsynaptic cell is terminated by the following: enzymatic degradation, diffusion or reuptake into the presynaptic cell by specific transporters.
Explanation: After a neurotransmitter has bound to its receptor on the postsynaptic membrane and triggered a biological response, in order to avoid over stimulation of the receptors, the neurotransmitter is either degraded by specific enzymes or taken back to the presynaptic cell into the synaptic vesicles by action of specific transporters. This mechanism is to maintain a balance (homeostasis).
These cells consume bacteria and other pathogens to protect the body from infection. The process begins when chemicals from a pathogen, or damaged tissue, attract a phagocyte. The phagocyte binds to the microbe, envelopes it, and then eats it.
Answer;
They fused into Pangaea
By the close of the paleozoic era all the continents fused into Pangaea.
Explanation;
Paleozoic era is the era of "ancient life".
During the early Paleozoic era, South America, Africa, Australia, Antarctica, India, and perhaps China comprised the vast southern continent of Gondwana.
At the beginning of this period, all continents joined together to form the supercontinent Pangaea, which was encircled by one ocean called Panthalassa.
I believe the answer would be the second option, B.
