Epidemic describes infections in a region whereas pandemic describes infections across countries/continents
What is the “Distal Convoluted Tubule”?
Answer:
The processing power of the mammalian brain is derived from the tremendous interconnectivity of its neurons. An individual neuron can have several thousand synaptic connections. While these associations yield computational power, it is the modification of these synapses that gives rise to the brain's capacity to learn, remember and even recover function after injury. Inter-connectivity and plasticity come at the price of increased complexity as small groups of synapses are strengthened and weakened independently of one another (Fig. 1). When one considers that new protein synthesis is required for the long-term maintenance of these changes, the delivery of new proteins to the synapses where they are needed poses an interesting problem (Fig. 1). Traditionally, it has been thought that the new proteins are synthesized in the cell body of the neuron and then shipped to where they are needed. Delivering proteins from the cell body to the modified synapses, but not the unmodified ones, is a difficult task. Recent studies suggest a simpler solution: dendrites themselves are capable of synthesizing proteins. Thus, proteins could be produced locally, at or near the synapses where they are needed. This is an elegant way to achieve the synapse specific delivery of newly synthesized proteins.

Answer: Venous bleeding
Explanation:
The external bleeding can be define as the bleeding in which the blood leaves the body due to external injury. The internal bleeding is the bleeding which occurs inside the body that may occur due to internal injury. There are about three types of external bleeding named as capillary, venous and arterial.
Capillary bleeding is most common and results from damage of tiny capillaries. Arterial bleeding is one of the serious type. The blood will spurt out from damage artery. It involves large amount of blood loss.
Venous bleeding occurs when a vein is subjected to cut, blood will steadily flow. If a deep vein is cut then the bleeding cannot be controlled and it can be fatal.
