The ring of fire is a circle that is covered with volcanos in its circumference. it erupts more that any other place because the more volcanos their are, the more these events will happen. another reason would be the tectonic plates. volcanos usually form on top of them. you must prepare for these events for your safety. their could be an earthquake any time, no mater where you are.
Recessive traits often seem to disappear because two recessive alleles are needed to produce the recessive phenotype. They can skip a generation and then reappear if an individual inherits two copies of the recessive gene. Mendel's experiments revealed that phenotypes could be hidden in one generation, only to reemerge in subsequent generations.
Recessive traits disappear because recessive alleles can hide out in heterozygotes, allowing them to persist in gene pools and natural selection can only see the phenotype, not the genotype. While harmful recessive alleles will be selected against and it's almost impossible for recessive alleles to completely disappear from a gene pool.

Red and blue. I hope this helped:)
Answer:
The options
A) "Efficient heart function requires that the ventricles do not retain any blood at the end of the cardiac cycle."
B) "Recall that the heart sounds that we listen to as part of our assessments are the sounds of the myocardium contracting."
C) "The diastolic phase is characterized by relaxation of ventricles and their filling with blood."
D) "Aortic pressure will exceed ventricular pressure during systole."
The CORRECT ANSWER IS C)
C) "The diastolic phase is characterized by relaxation of ventricles and their filling with blood."
Explanation:
Diastole is connected with ventricular filling and relaxation. Cardiac production is not 100% or in proximity to been 100% with every cardiac cycle, as the heart sounds are linked with valve closure. Ventricular pressure surpasses that of the aorta in the course of the systole.
