Therefore, fungi are the correct answer in this context.
10.
Type of fungus that affects plants or grows on in animate objects but does not cause human infections in the salon setting
Correct Answer
B. Mildew
Explanation
Mildew is a type of fungus that affects plants or grows on inanimate objects but does not cause human infections in the salon setting. It is commonly found in damp and humid environments, such as bathrooms and basements. Unlike mold, which can cause health issues in humans, mildew is generally not harmful to people. It can, however, cause damage to surfaces and fabrics if left untreated. Therefore, it is important to address mildew growth and take necessary measures to prevent its spread in order to maintain a clean and healthy environment.
11.
Plant or animal organisms that derive nutrition from another organism
Correct Answer
B. Parasites
Explanation
Parasites are plant or animal organisms that derive nutrition from another organism. They depend on their host organism for survival and obtain nutrients from them, often causing harm or damage in the process. This relationship is usually detrimental to the host organism, as parasites benefit at their expense. Pathogens, streptococci, and fungi can all be types of parasites, depending on their specific characteristics and interactions with their host organisms.
12.
Skin disease caused by infestation of head lice
Correct Answer
B. Pediculosis capitis
Explanation
Pediculosis capitis is the correct answer because it refers to a skin disease caused by the infestation of head lice. Dandruff is a common scalp condition characterized by flaking and itching, but it is not caused by lice. Streptococci are bacteria that can cause various infections but are not related to head lice infestation. Scabies is a contagious skin condition caused by mites, not lice.
13.
Powerful tuberculocidal disinfectants
Correct Answer
A. pHenolics
Explanation
Phenolics are powerful tuberculocidal disinfectants. They are effective against tuberculosis-causing bacteria and have strong antimicrobial properties. Phenolics work by denaturing proteins and disrupting the cell walls of microorganisms, leading to their destruction. They are commonly used in healthcare settings and laboratories for disinfection purposes. Sodium hypochlorite, another option listed, is a strong disinfectant but is more commonly used as a general-purpose cleaner and bleach. Fungicidal properties are not specifically mentioned in the given options, and quaternary ammonium compounds are more commonly used as disinfectants against bacteria and viruses rather than tuberculosis.
14.
Spiral or corkscrew-shaped bacteria that can cause diseases such as syphilis and Lyme disease
Correct Answer
D. Spirilla
Explanation
Spirilla are spiral or corkscrew-shaped bacteria that can cause diseases such as syphilis and Lyme disease. This makes them the most suitable option among the given choices. Flagella are whip-like structures used for movement and are not specific to any particular shape of bacteria. Streptococci are spherical bacteria arranged in chains, while bacilli are rod-shaped bacteria. Therefore, neither of these options fit the description of spiral or corkscrew-shaped bacteria.
15.
Pus-forming bacteria that grow in cluster like bunches of grapes, can cause abscesses, pustules and boils
Correct Answer
C. StapHylococci
Explanation
Staphylococci are pus-forming bacteria that grow in cluster-like bunches of grapes. They can cause abscesses, pustules, and boils. Streptococci are bacteria that grow in chains and can cause various infections, but they do not typically form clusters like grapes. Spirilla are spiral-shaped bacteria that can cause diseases such as syphilis and Lyme disease, but they do not typically form clusters or cause abscesses. Cocci is a general term for spherical-shaped bacteria, but it does not specify the cluster-like growth pattern or the ability to cause abscesses. Therefore, staphylococci is the correct answer.
