membrane bound organelles in a cell actually contain DNA of their own so they don't have to actually rely on the rest of what the cell is doing in a similar manner, just because your breathing doesn't mean that your kidneys are working at the same time each one is actually independent of its own actions
Tissues and organ systems.
here is the full chart:
cell --> tissue --> organ --> organ system --> organism
(think: group of [insert former here])
e.g. tissue=group of same cells

Answer:
the external oblique.
Explanation:
<u>the external oblique</u> covers the ventral, abdominal region in rats.
The disorder where the grandfather and the grandchild are affected is related with the X chromosome and is called Sex linked or X linked disorder.
<h3><u>Explanation:</u></h3>
All the sex linked disorders are recessive in character i.e the normal allele is dominant over the mutated allele. In females, there are 2 X chromosomes, so the mutated allele is only expressed when there are both the mutated alleles, else its masked by the dominant normal allele. But in males, there's only one X chromosome, so if a mutated allele is present, it's readily expressed.
If the Grandfather is diseased, then he must have that mutated allele in X chromosome. Through reproduction, its received by the mother, but she is normal because the other allele received from grandmother was normal. But mother has one of the X chromosomes with mutated allele, which is received by the grandson who again becomes diseased.
So the disorder must be X linked disorder
