Antibiotics are medicines that help stop infections caused by bacteria. They do this by killing the bacteria or by keeping them from copying themselves or reproducing.
Antibiotics are used to treat or prevent some types of bacterial infections. They are not effective against viral infections, such as the common cold or flu. Antibiotics should only be prescribed to treat health problems: that are not serious but are unlikely to clear up without antibiotics – such as acne.

Explanation:
The microsystem is one of the component of ecological system theory. The microsystem describes the system, which is close proximity to the person.

Answer:
The correct answer is - XTXt
Explanation:
In the question, it is given that in cats the coat color is an X-linked trait that shows incomplete dominance if present in heterozygous condition.
The allele for yellow allele = XT (it is dominant allele)
The allele for black coat = Xt (it is recessive allele)
The amle cat can not show the heterozygous condition or tortoise coat as they have only one X chromosome so they will be either yellow coat cats or black coat cats.
In female cats the tortoise coat will show when the both allele present together: XTXt due to their incomplete dominance.
