Answer:
True
Explanation:
Pacemaker cells, unlike other neurons in the body, can depolarized themselves (and therefore can fire action potentials) without the need of an external innervation of the autonomic nervous system.
Each class of pacemaker cells has its own intrinsic rate.
For example, sinoatrial node rate is 60-100 bpm (the normal heart frequency).
The atrioventricular node is also part of the electrical conduction system of the heart. When the sinoatrial node fails, atrioventricular node takes the lead (40-60 bpm).

The best answer for the nurse to give is "You will be sedated but not asleep." Persons who are undergoing cardiac catheterization will receive a sedative but are not put to sleep. Their cooperation is needed during the procedure.
<h3>What is cardiac catheterization?</h3>
- During a cardiac catheterization procedure, a thin, flexible tube (catheter) is directed into a blood vessel to the heart in order to identify or treat certain heart disorders, such as blocked arteries or irregular heartbeats.
- The most common reason for performing this operation is to learn more about the heart or its blood arteries.
- Additionally, it could be carried out to determine whether you require heart surgery or to treat specific heart diseases.
- Cardiovascular catheterization may be used by your doctor to identify or assess: Cardiomyopathy or congestive heart failure causes.
- It takes a week or less for full recovery. For 24 to 48 hours, keep the region dry where the catheter was implanted. The recuperation process is frequently quicker if the catheter was placed into your arm.

Answer:
Modern people are using the Earth for many things like farming, technology, art, and more.
Explanation:
Farming is a form of agriculture, people who farm can make money off of selling their crops, and they can also feed themselves.
Technology is a mix of mathematics, science, and the arts. Without technology, phones, laptops, cars, and other electronics would not exist right now. We need cars for transportation to get from Point A to Point B, and we use our phones and laptops for communication and entertainment.
Art is the form of human activities in creating visual, auditory or performing artifacts. Without art, life wouldn't be very pleasurable. People want to express themselves, and people want to see beauty. Art also helps historians tell about the past.
Hope this helped!
