Answer:
Yes, I agree with the given statement.
Explanation:
Plants undergo the process of photosynthesis for the production of their food. In this process, they require the presence of sunlight, carbon dioxide, water, minerals, and chlorophyll. The process of photosynthesis is possible only during the day because sunlight is one of the major components. Carbon dioxide is taken in by the plant through the stomata from the environment. The oxygen is formed as a product of the process and is released in the environment. This process becomes impossible during the night because of the absence of sunlight. The entire process sums up to that the plants give out oxygen during the day and give out carbon dioxide during the night.
I think the answer is B because it happens slowly and through natural selection
The amiodarone belongs to <u>class III </u>of the Vaughn-Williams classification system of antidysrhythmic medications.
<h3>
What is antidysrhythmic medications?</h3>
Antiarrhythmic drugs comprise many different drug classes and have several different mechanisms of action. Furthermore, some classes and even some specific drugs within a class are effective with only certain types of arrhythmias. Therefore, attempts have been made to classify the different antiarrhythmic drugs so by mechanism. Although different classification schemes have been proposed, the first scheme (Vaughan-Williams) is still the one that most physicians use when speaking of antiarrhythmic drugs.
The following shows the Vaughan-Williams classification and the basic mechanism of action associated with each class.
- I - Reduce phase 0 slope and peak of action potential.
- IA - Moderate reduction in phase 0 slope; increase APD; increase ERP.
- IB - Small reduction in phase 0 slope; reduce APD; decrease ERP.
- IC - Pronounced reduction in phase 0 slope; no effect on APD or ERP.
- II - Block sympathetic activity; reduce rate and conduction.
- III - Delay repolarization (phase 3) and thereby increase action potential duration and effective refractory period.
- IV - Block L-type calcium-channels; most effective at SA and AV nodes; reduce rate and conduction.

Answer:
The slope between the red points is 2/4 (simplified it is 1/2). The slope between the green points is 4/8 (simplified it is 1/2). This shows that by taking ANY two points on the line, you will find the same slope.
