Answer:
Nondisjunction during sperm arrangement and formation brought about her getting no sex-chromosome from her dad and an X chromosome from her mom, she is XO.
Explanation:
Nondisjunction during sperm arrangement and formation brought about her getting no sex-chromosome from her dad and an X chromosome from her mom; she is XO.
It is on the grounds that her mother happens to be a carrier of hemophilia and she transferred that mutant allele to her daughter and due to the fact that she did not get any sex-chromosome from her dad.
However, such mutant (X) communicates and expresses itself and she is hemophilic.
This (X) is not express in her mother because she possesses a recessive trait; as such it appears in the hom8zygous state.

<u>ANSWER:</u>
Cosmic background radiation is leftover thermal energy from the Big Bang best describes the origin and expansion of the universe.
<u>EXPLANATION:</u>
- The "Big Bang Theory" is used to describe how the universe has begun.
- The theory basically states that the "universe" began as a "single point" and then "expanded and stretched" and is expanding even today.
- When the universe began, it was "hot tiny particles" mixed with heat and light and as it "expanded" and took up "more space", it cooled down and formed atoms.
- The "best evidence of the big bang" is the radiation of cosmic background that was leftover when the first big bang explosion took place and began the universe.

Explanation:
Microtubules are polymers of tubulin and they are part of the cytoskeleton. The roles of the microtubules are to maintain the shape and structure of the cell, intracellular transport, they are structural part of the cilia an flagella, they are involved in cell division etc.
Tubulin that is the basic unit of microtubules is composed of two globular proteins, alpha and beta tubulin. Alpha and beta subunits spontaneously form dimers which then assemble into oligomers, then in chains (protofilaments); that can form a variety of intermediate structures such as single and double rings or spirals. Protofilaments that associate side-by-side form sheets of protofilaments which then curle to form a tube or cylinder (closing of microtubule). Continued growth of microtubules occurs by the direct addition of more dimers on + side.
