Explanation:
1. Barr body is a drumstick-like structure of dense, coiled chromatin that appears normally in female's buccal cells and neutrophils. It represents the inactive X-chromosome (Females have two X-chromosomes. Only one is active.)
2. Liver cells are somatic, not sex cells and are thus diploid.
Inbreeding i believe..... you can have same set of alleles if related
Answer:
Infrared images also show thermal, or heat, radiation. While a visible-light image from this vantage point would simply show the face of the planet as dimly lit by sunlight reflected off the rings, Saturn glows brightly in this view because of heat from Saturn's interior.
In a second version of the image, scientists "stretched" or exaggerated the contrast of the data, which brings out subtleties not initially visible.
When these small particles are lit from behind, they show up like fog in the headlights of an oncoming vehicle.
• The C ring also appears relatively bright here; not because it is made of dust, but because the material in it -- mostly dirty water ice -- is translucent. In fact, in the 18th and 19th centuries, it was known as the "crepe ring" because of its supposed similarity to crepe paper.
• The wide, middle ring known as the B ring -- one of the easiest to see from Earth through telescopes because it is densely packed with chunks of bright water ice -- looks dark in these images because it is so thick that it blocks almost all of the sunlight shining behind it.

hope i helped :)
A. Nucleotides; they are molecules that form basic structural units
Answer:
The correct answer will be option-E
Explanation:
Cyanide is a poisonous substance which is considered the inhibitor of the cellular respiration. The cyanide inhibits the process by inhibiting the complex IV which transfers the electrons to the oxygen thus, block the transfer of the electron.
The isotonic solution is the solution which contains an equal amount of solute to the cell, as a result, no osmotic gradient develops. This leads to the no movement of solute across the semipermeable membrane. When a cell is placed in the isotonic solution, the cell remains unaffected.
Thus, option-E is the correct answer.
