According to the National Institute of Health, ventricular tachycardia is a fast, regular beating of the ventricles that may last for only a few seconds or for much longer. A few beats of ventricular tachycardia often doesn't cause problems. However, episodes that last for more than a few seconds can be dangerous. Ventricular tachycardia can turn into other, more serious arrhythmias, such as ventricular fibrillation.

Based on the passage above, how will prolonged ventricular tachycardia affect blood pressure?

It will increase blood pressure because the ventricles are contracting with more force.
It will increase blood pressure because the ventricles are filling with more blood between beats.
It will decrease blood pressure because there is a longer rest period beats of the ventricles.
It will decrease blood pressure because the ventricles are filling with less blood between beats.

I know it will decrease. The venticles are filling with less blood between beats most likely since the heart is beating faster. (I hope this helps!)

Explanation:

the cost of mining is extremely low compared to the money earned from mining, creating income to improve the environment.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
