A procedure which uses a catheter with an electrode in its tip to destroy the cells from which abnormal cardiac rhythms are originating is called Ablation.
Ablation therapy is used to treat some rhythm abnormalities. While cryo or freezing ablations have been used to address a number of rhythm issues, the bulk of ablations are performed using radiofrequency energy and catheter heating.
invasive intracardiac testing is necessary even though radiofrequency ablation is frequently safe and effective. The tissue is heated to a temperature of 45–100 °C using radiofrequency energy and an alternating current of 370–50 kHz. The catheter-induced lesion has dimensions of 5–6 mm in diameter and 2–3 mm in depth. To treat certain rhythm issues, like VT , a catheter with a larger tip, also known as an "irrigated tip," is used to make deeper and larger lesions.

The correct answers are:
1. hominoids;
The hominoids are a group of primates which is consisted of large species of monkeys. They are one of the most developed animals on the planet, intelligence wise. The great apes are the closest relatives to the modern humans, and the group of the hominids as a whole.
2. hominids;
Intelligence wise are the most developed group of animals on the planet. They originated from the great apes, but evolved in a totally different manner where they became bipedal, and also developed an extra bone in the thumb, and that enabled them to develop even more, and over time to become the most dominant species on the planet. In this group we have the likes of Australopithecus, Homo habilis, Homo erectus, Homo florensis, Homo sapiens etc.
Answer:
It is a single stranded DNA since adenine percentage is not equal to that of thymine and the percentage of guanine is not equal to cytosine.
Explanation:
According to Chargaff rule, the amount of adenine in a double-stranded DNA is always equal to that of thymine. This is due to the fact that adenine pairs with thymine in a double-stranded DNA. Likewise, the amount of guanine is always equal to that of cytosine in a double-stranded DNA.
The percentage of four types of bases in the genome of the virus does not follow the Chargaff rule and hence, it is a single-stranded DNA.
