Answer:
The probability of the study result being subject to bias while interpreting -------- it's a YES
Explanation:
Probability of Leukemia
A. Among traced group
= 4/1,870 persons.
B. Among self-reported group
= 4/443 person.
We can deduce
A higher rate of occurrence in self-reported group which could be causesd by fear of leukemia occurrence or suspicion of their previous exposure at atomic sites
A condition in which the force of the blood against the artery walls is too high.
Usually hypertension is defined as blood pressure above 140/90, and is considered severe if the pressure is above 180/120.

Please find the detailed explanation of this statement below
Explanation:
Firstly, a repressed gene is a gene whose expression has been inhibited or repressed. The lac operon in E.coli bacteria is a regulatory unit containing structural genes, a single promoter and operator regions. The promoter is the region where the transcription enzyme (RNA polymerase) binds to in order to transcribe the genes in the lac operon. The structural genes in the lac operon can only be expressed in the presence of lactose sugar.
However, in the absence of lactose, LAC REPRESSOR, which is a transcription factor (protein), prevents the binding of RNA polymerase to the PROMOTER region by binding to the OPERATOR region of the lac operon. This inhibits the expression of the lactose genes in the operon.
Note that, the structural genes in the lac operon (lacZ, lacY, lacA) code for proteins that help break down lactose sugar for energy in the E.coli bacteria. Therefore, a bacteria cell with a repressed lac operon will be unable to degrade lactose sugar.
The worm feeds via a "pumping" action in which it first uptakes the fluid surrounding it. Then, it expels the fluid while trapping any bacteria within it. The bacteria are then digested for energy and nutrients.
