The answer is spread/dispersal of the parasite. They
increase the probability of infection of the definitive host. The intermediate
host can either be present or absent in the parasitic life cycle. They are
considered an ecological than a
physiological phenomenon for the transmission of the parasite.
Answer:
The postsynaptic cell has many synapses with many presynaptic neurons
Explanation:
Spatial summation is a process of producing an action potential in a neuron with input from multiple presynaptic nerve cells. This process determines whether an action potential will be triggered upon reaching threshold from multiple synapses with presynaptic neurons. Summation of all inputs determines if an action potential will b generated.
B is the answer because it the ER helps with protein transport.
Atlantic Cod is a marine fish. The fish has less salt in its internal body while the salt concentration in the sea water in which the Cod lives is high. Thus through the process of osmosis ( a process in which an element moves across a permeable membrane from regions of high concentration to the regions of low concentration) the salt moves from the ocean into the fish body. In such scenario the metabolism of the fish body gets disturbed, and there is an urgent need to remove the excess salt with the help of Kidney (through extremely concentrated urine) by going against the concentration gradient in order to maintain the homeostasis.
