Cross Contamination ::

Cross Contamination is nothing but a contamination in a cross way i.e, when a bacteria on a kitchen tool transfers to food via direct contact. Two of the most common kitchen tools usually tend to be a knife or a cutting board. However, it is not just bacteria that gets carried from one place to another — it could also be a virus also.

Cross Contamination is prevented by the following tips ::

1. Use separate equipment

2. Clean and sanitize all work surfaces

3. Remind employees to wash their hands

4. Purchase prepared food

5. Implement a personal hygiene program.

Benign prostatic hyperplasia (BPH) also called benign prostatic hypertrophy (or) prostate gland enlargement is a noncancerous enlargement of the prostate gland that can lead to lower urinary tract symptoms (LUTS).

As the prostate gets larger, it starts to pinch the urethra. This causes symptoms that affect your urine flow, such as:

* Dribbling when you finish

* A hard time getting started

* A weak stream, or you pee in stops and starts.

The principle of dominance states that some alleles are dominant, while others are recessive.

Ribosomes comprise a complex macro molecular machine, found within all living cells, that serves as the site of biological protein synthesis. Ribosomes link amino acids together in the order specified by messenger RNA molecules.

Fluoride deficiency is a disorder which may cause increased dental caries due to a lack of fluoride in the diet. Dental caries or tooth decay is the breakdown of dental tissues by the acidic products released by the "bacterial fermentation of dietary carbohydrates”
