The expected result of this poison on secondary active transport is that the poison will prevents the conformational changes which are necessary for the pump to perform its function, thus preventing it from been able to carry out transportation of ions in and out of the cell.
Answer:
The correct answer will be option A.
Explanation:
The electrical impulses are generated in the sino-atrial node or SA node, a mass of cells which generates impulse in the upper atrium.
This electrical impulse transmits from the sino-atrial node to the atrio-ventricular node in the lower portion of the upper atrium through the internodal pathway- the pathway composed of atrial cells.
Once the impulse reaches the AV node, it is transferred to the ventricular portion of the heart through Bundle of His presence in the ventricular septum. This bundle of his divides into left and right ventricles through bundle branches and stimulates both the ventricles.
Thus, option-A is the correct answer.
Answer:
Option E, C tactile (CT) afferent
Explanation:
Whenever a slow moving gentle touch experienced, the response is due to the nerve fibers called C-Tactile afferents (CTs).
C-Tactile afferents (CTs) are unmyelinated mechanoreceptors of low threshold and low conduction velocities.
In humans, CT neurons are found in hairy skin.
The pleasant feeling observed during a slow gentle touch is due to the interaction of
CT neurons project to the insular cortex in the brain
Hence, option E is correct
The amswer would be B beaucause the excretory system could ger rid of soild and waste
