Answer:
C. right side of the head and neck and right upper arm
Explanation:
The arch of aorta is a continuation of ascending aorta and terminates at the intervertebral disc of fourth and fifth thoracic vertebrae. The superior part of the arch of aorta branches off into three major arteries. The first branch of arch of aorta is the largest branch and is known as the brachiocephalic trunk.
The brachiocephalic trunk divides and forms the subclavian artery and right common carotid artery. Right common carotid artery supplied blood to the right side of the head and neck while the right subclavian artery delivers blood to the right upper limb.
Hence, any blood clot in the first branch of arch of aorta, that is the brachiocephalic trunk would affect the blood supply to the right side of the head and neck and right upper arm.
Parallel circuits are circuits when placed in a parallel
position. Meaning that for each device, they have their own branch. The voltage
that is received in the circuit is equal to the individual devices. The total
current is equal to the current of each device. The resistance is the reciprocal
of the resistances of each device combined.
Given:
Device 1 = 12 ohms
Device 2 = 4 ohms
Voltage total = 40V
Required:
Current at 12 ohms
Solution:
40V = V1 =V2
Since V =IR
I1 = V1/R1
I1 = (40V)/(12 ohms)

One example: The improvement in science and technology over the years has decreased the infant mortality rate. Since more babies live, we have a higher population.
Also, with increases in science and technology, there are many diseases that were once considered fatal that are now easily treated. This has also led to a higher population.
