Answer:
The upper region of the body veins carries blood that has no oxygen to the heart through superior vena cava and the lower part of the blood with no oxygen will transfer to the heart with the help of superior vena cava.
In Right hand:
At first, blood in the palmar region or distal end of the arm deoxygenated blood from this side will go to the following manner -
right ulnar vein - to the right Axillary vein - to the right subclavian vein - Right internal jugular vein - right brachiocephalic vein and finally it reaches the superior vena cava of the heart.
The same pathway will take place on the left side of the upper region of the body.
Answer:
The correct answer is option e, that is, unpaired loop.
Explanation:
For base pairing to take place, the duplicated or the deleted region will not possess any kind of complementary region. Thus, it produces an unpaired loop. The formation of the inversion loop takes place at the time of paracentric and pericentric inversion. A high-level packaging composition produced by chromatin is known as a solenoid. A bead on string structure produced by enveloping DNA around the core of histone proteins is termed a nucleosome.

as acidophilic bacteria survive without oxygen in acids ...so !!!
