Answer:
All of the following factors contribute to hospital-acquired infections EXCEPT d. None of the answers is correct.
Explanation:
<em>All of these factors may contribute to hospital-acquired infection.</em> Some bacteria metabolize disinfectants, gram-negative bacteria are often resistant to disinfectants, bacteria may be present in commercial products such as mouthwash and it is true that invasive procedures can provide a portal of entry for bacteria. Patients are at high risk.

Answer:
D (purple flower plant is dominant)
Explanation:
Gregor Mendel was regarded as the "Father of Genetics" because of his outstanding contribution to discovering the pattern of inheritance. In his experiments with purebreeding purple and white-flowered plants, he discovered that the F1 offsprings were all purple-flowered.
This observation made him to propose his LAW OF DOMINANCE, which states that one allele of a gene is capable of masking the expression of another in a heterozygous state. In this case of flower colour gene, the allele for purple color (P) is masking the gene of the white colour (p) in a combined state. Hence, purple allele is said to be DOMINANT over white allele.
He discovered that the white allele was being masked when he performed a dihybrid cross i.e. F1 self cross to derive a plant with white flowers.
