I had this question when I took a biology class cuz I chose to study a lot on paleontology :)
It’s that there’s fossils of animals in geological strata that are older than the Cambrian explosion.

The first answer is the correct one. Osmosis is only water and diffusion is everything else across a semi-permeable membrane.
Answer:
The correct answer is - B. Non-disjunction during sperm formation resulted in her receiving no sex chromosome from her father and an X chromosome from her mother; she is XO.
Explanation:
In this case, the mother was a carrier of hemophilia and she transfers that mutant allele to her daughter and as the daughter did not get any sex chromosome from her father.
Therefore, mutant X expresses itself and she is hemophilic.
This X did not express in case, of her mother due to fact that it is a recessive allele and only expresses when both genes is the same state.
Each time a cell divides into two daughter cells, its full genome is duplicated; for humans and other complex organisms, this duplication occurs in the nucleus. This minimizes the incidence of errors (mutations) that may greatly affect the resulting organism or its offspring. ...
