This is the correct sequence of events of the cardiac cycle.

Answers

Given what we know we can confirm that the correct sequence of events for the cardiac cycle is atrial systole, ventricular systole, atrial diastole and  ventricular diastole.

What is the cardiac cycle?

The cardiac cycle is what we define as the cycle in which the heart beats. This cycle begins with the systole of both the atria and the ventricles, in which they contract, first the atria, then the ventricle. This is to pump blood into the next part of the circulatory tract. This is followed by the diastole of each cavity, in which they fill with blood once more.

Therefore, we can confirm that the correct sequence of events for the cardiac cycle is atrial systole, ventricular systole, atrial diastole, and ventricular diastole.

The correct sequence of events of the cardiac cycle is :

Ventricular filling --->  isovolumetric contraction ---> ventricular ejection --> isovolumetric relaxation

Meaning of cardiac cycle

Cardiac cycle is a measure of the heart performance start form a single beat to the beginning of the next heartbeat. it occurs in four phases which starts with the Ventricular filling phase and ends with the isovolumetric relaxation.

Hence we can conclude that the correct sequence of events of cardiac cycle is as listed above.

Reproduction

Heredity

Variation in fitness of organisms.

Due to these reasons, natural selection can leads to speciation.

As the individual are living in cold environment, they need to adapt the change in environment. So, individuals with thicker fur had a survival advantage in the cold environment, allowing these individuals to reproduce more often and create more offsprings.

Thus, option C is correct.

Proteins of smaller molecular size may be reabsorbed from the glomerular filtrate by the specific transport process of endocytosis.

What do you mean by Glomerular filtrate?

The Glomerular filtrate may be defined as the liquid in the lumen of the Bowman's capsule of the nephron that has been purified from the capillaries of the glomerulus.  

The small molecular size proteins may be absorbed from the glomerular filtrate by receptor-mediated endocytosis. Then moved into the endosomes, and finally to the lysosomes for the degradation.

What are linked genes?

Linked genes have to do with inheritance. Linked genes are those that are very likely to be inherited together, though not a guarantee, due to their position in the chromosome being very close to one another. This also means that these genes do not separate during meiosis.
