A sex-linked trait is a trait that is carried by the X chromosomes in females but it is not expressed(the phenotype). Females are only carriers because they have two copies of the X chromosome [one of them carries the trait and the other does not]. Males who inherit one copy of the X chromosome often get the trait (because the trait is in either one copy or the other of the X chromosome) and express it while their Y chromosome would became recessive. Thus, only males express sex-linked traits such as hemophilia or color blindness
The answer is Retroviruses integrate DNA randomly in the
genome. While retroviruses integrate their
DNA permanently in their host genome, hence
a good tool for gene therapy, its risk of inserting
DNA at an unintended
location on target genome can cause insertional
mutagenesis. This mutation can cause activation of oncogenes hence lead to tumor
growth.
Answer: C.) Aluminum

Hope this helps. :)
Answer:
Phase 3
Explanation:
Phase 3 of the systems development life cycle describes the desired features and operations of the system. The objective of the systems design phase is to transform all requirements into detailed specifications covering all aspects of the system. It should also assess and plan for security risks. Finally, approval to progress to the development phase must be granted to complete the systems design phase.
