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.

Answer:
Female egg cells grow in the ovary.
Explanation:
If we talk about female reproductive system in animals or particularly humans, ovaries are basically the sites where female egg cells are produced. These egg cells are also termed as oocytes or ova. After the production, they are transferred to fallopian tubes where the sperm is also reached and ultimately fertilization occurs. Once the egg gets fertilized, it moves towards another site called uterus. The walls of the uterus get thicker and thicker due to production of specific hormones and help in supporting the baby. You can see attached image for better understanding.
<em>Note: </em><em>The female egg cells grow in ovary but here we specifically focussed on human females. The option is true for all animals.</em>

This happens through the food chain. Herbivores eat the plants and carnivores eat the herbivores. If plants did not use photosynthesis,they would die from lack of energy and the other organisms would suffer as well.
