Antibiotic resistance occurs naturally and it is use as medicines as well as misuse of antibiotics in humans ans animals is accelerating the process.
Nowadays infections are growing such as gonorrhea, tuberculosis, pneumonia, etc all are becoming hard to treat or fight with them because of less effective antibiotics.Inappropriate uses of antibiotics spread antibiotic resistance bacteria.
Excessive use of antibiotics or use for wrong reasons can cause bacteria to became resistant and multiply rapidly in human body or environment. When bacteria develop the ability to survive exposure of antibiotics that are design to kill them or stop their growth. Young children, cancer patient and over age people at great risk.

Answer:
The presence of freckles in a individual, or predisposition to have them, is a trait that is inherited with an autosomal dominant pattern, and is not related to sex-linked inheritance.
Explanation:
Freckles are accumulations of melanin in the skin, which form small reddish or light brown spots, predominantly in white-skinned people.
<u>
The melanocortin receptor gene</u> undergoes a change that gives rise to a variant - which is phenotypically expressed in the presence of freckles - whose inheritance has been determined to be autosomal dominant.
<u>Under no circumstances is the transmission of the gene that determines the presence of freckles linked to sex</u>, because is an autosomal trait, as is hair, eye or skin color.

The correct answer is: B) recognition of the prokaryotic promoter by RNA polymerase
The similarities between prokaryotic and eukaryotic transcription are that DNA is template used for the mRNA synthesis and that this is process is facilitated by the enzyme RNA polymerase.
One of the difference between this process in eukaryotes and in prokaryotes is the promoter region: eukaryotes contain TATA box and CAT box, while prokaryotes don’t (they have Pribnow box that is similar to the TATA box). Promoter region in prokaryotes is always upstream to the start site, while in eukaryotes it can be downstream.
