1. What causes the autorhythmicity or action potentials of the nodal cells? a. A decrease in chloride permeability b. A gradual
Sveta_85 [38]

Answer:

The correct answer will be option-C

Explanation:

The rhythm of the heartbeat is controlled by the pacemaker of the heart called the sino-atrial node.

The SA node generates action potentials which trigger the contraction and relaxation of the atrium and ventricles. The membrane potential generation initiates by the depolarization of the cell membrane when the L type of Ca⁺² ions opens up and calcium ions enter the cell.

This depolarizes the cell until the potential threshold is reached which lies between the -40 and -30 mV.

Thus, Option-C is the correct answer.

Why are fungi fossils so rare?
Volgvan
The reason as to why fungi fossils seem so rare is that they are usually microscopic and often difficult or impossible to identify. Not much information on fungi fossils has been documented. This could be because fungi fruiting bodies consist of soft, fleshy and easily degradable tissues which due to their poor integrity do not keep or preserve as well as animal tissue. Even when available, it takes a trained eye to recognize fungal fossils. Not many people have the training and expertise to recognize the fossils.
