Diastole is the ________ phase of the cardiac cycle.

STatiana [176]

Diastole is the relaxation phase of the cardiac cycle. It is the normal rhythmic dilation of the heart's valves. During this time, the valves start to gather blood inside of their chambers. There are two types of diastole that occur in the heart, and they are:

1. Ventricular diastole - this is the period where the ventricles are filling and relaxing.
2. Atrial diastole - the period in which the atria are relaxing.

This is a continuous cycle that occurs in the heart the moment a person is conceived until the person meets his/her death.

Drupady [299]

Answer:

The new drug will not be effective against the treatment of cancer.

Explanation:

The drug will not be effective against the cancer treatment because the drug will inhibit the dimerization of receptor tyrosine kinase (RTK) but as the Ras has undergone mutation due to replacement of one amino acid, it will be constitutively expressed and the drug is not effective in stopping the Ras functioning.

Thus, Gefitinib cannot work against the cancerous cell as it is not potent to stop the functioning of mutant Ras protein.
