In this cross the trait of long tail fins is associated with the “Y” chromosome of the male.
Thus the alleles of the male are represented by XY” where X chromosome has no trait of long tails find
And the allels of the female are represented by XX, as they do not have long tail fins.
When these two are crossed , the following punnet square is produced
X Y”
X X X X Y”
X X X X Y”
The XX is the female while the XY” is the male offspring.

There doesn't seem to be a maximum number. Ultra high molecular weight polyethylene has around 500 thousand carbons that are linked together.
Answer:
True
Explanation:
The scala vestibuli contain perilymph in which there is a domination of Na+ ion which is K+ in endolymph. endolymph has domination of K+ because they have very large potential as compared to perilymph this is also called endocochlear potential . there is a potential difference of about 150 mV across the stereocillary membranes that drive cations through mechanotransduction channels
