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.

An engineer is building a new steel skyscraper in a area with a lot of Earthquakes, Compare two systems (fixed based system and

Leokris [45]

Answer:

<h2>Base isolated system</h2>

Explanation:

Fixed based system:-

A fixed-base building (built directly on the ground) will move with an earthquake’s motion and can sustain extensive damage as a result.

Base isolated system:-

A base isolation system is a method of seismic protection where the structure (superstructure) is separated from the base (foundation or substructure).

Hence,

A base isolated system is much more better in a area where there are a lot of earthquakes.

"cell structures is the permeability layer that lets only a selective number and type of molecules into the cell?"

Montano1993 [528]

Answer: Cell membrane

Explanation:

The cell membrane has the ability to transfer the molecules from the exterior of the cell to the interior of the cell.

The cell membrane is semi permeable which means only selected molecules will pass through the cell membrane.

The molecules and substances that are synthesized inside the cell needs to be transported from inside to outside via cell membrane.
