1.
A disease caused by the physician (veterinarian)
Explanation
Iatrogenic refers to a disease or condition that is caused by medical treatment or intervention. In this case, the term "iatrogenic" suggests that the disease is caused by the actions or treatment provided by a physician, specifically a veterinarian. This could imply that the disease is a result of a mistake, error, or unintended consequence of the veterinarian's actions, rather than being naturally occurring or caused by other factors.
2.
Within an artificial environment
Explanation
The term "in vitro" refers to experiments or processes that are conducted outside of a living organism, usually in a controlled laboratory setting. In this context, "within an artificial environment" is synonymous with "in vitro." Therefore, the correct answer is "in vitro."
3.
A fingal skin infection
Explanation
Dermatophytosis is a fungal infection of the skin, hair, or nails caused by dermatophytes. These fungi thrive on dead tissues such as skin, hair, and nails, leading to various symptoms like itching, redness, and scaling. Fingal skin infection is a common term used to describe dermatophytosis specifically affecting the skin of the fingers. Therefore, dermatophytosis is the correct answer for this question.
4.
Two living organisms of different species living together.
Explanation
Symbiosis refers to a mutually beneficial relationship between two different species living together. In this type of interaction, both organisms rely on each other for survival and receive some form of benefit. This can include sharing resources, protection, or even assistance in reproduction. Symbiosis can take various forms, such as mutualism (both species benefit), commensalism (one species benefits while the other is unaffected), or parasitism (one species benefits at the expense of the other). Therefore, the concept of symbiosis accurately describes the relationship between two living organisms of different species living together.
5.
Drugs used to eliminate helminth parasites (e.g. roundworms) from a host
Explanation
Anthelmintics are drugs specifically designed to eliminate helminth parasites, such as roundworms, from a host. These parasites can cause various diseases and health issues in humans and animals. Anthelmintics work by either paralyzing or killing the parasites, allowing them to be expelled from the body. They are an essential tool in the treatment and prevention of helminth infections, helping to improve the health and well-being of individuals and animals affected by these parasites.
6.
The use of a patch applied to the skin to deliver a drug through an intact cutaneous surface to the systemic circulation.
Explanation
Transdermal application refers to the use of a patch applied to the skin to deliver a drug through an intact cutaneous surface to the systemic circulation. This method allows for the drug to be absorbed directly into the bloodstream, bypassing the digestive system. It is a convenient and non-invasive way of drug administration, providing a controlled and continuous release of the medication over a prolonged period of time. Transdermal patches are commonly used for delivering medications such as hormonal contraceptives, pain relievers, and nicotine replacement therapy.
7.
A disease or syndrome characterized by inadequate amounts of corticosteroid hormones.
Explanation
Addison's Disease is a medical condition that occurs when the body does not produce enough corticosteroid hormones. This can lead to various symptoms such as fatigue, weight loss, low blood pressure, and darkening of the skin. The disease is caused by damage to the adrenal glands, which are responsible for producing these hormones. Treatment for Addison's Disease typically involves lifelong hormone replacement therapy to manage the symptoms and prevent complications.
8.
Within the living body
Explanation
"In Vivo" refers to experiments or studies conducted within a living organism, such as animals or humans. This term is used to describe research that involves observing and analyzing biological processes or the effects of substances within a living body. It is commonly used in contrast to "In Vitro," which refers to experiments conducted outside of a living organism, typically in a laboratory setting.
9.
An agent with the capability to KILL bacteria.
Explanation
Bactericidal refers to an agent or substance that has the ability to kill bacteria. This term is used to describe the action of certain antibiotics or disinfectants that are specifically designed to eliminate bacteria. Unlike bacteriostatic agents which only inhibit the growth and reproduction of bacteria, bactericidal agents actually destroy the bacteria, leading to their death. Therefore, the term "bactericidal" accurately describes an agent with the capability to kill bacteria.
10.
An agent that INHIBITS the growth or reproduction of bacteria. (doesn't kill them, just interferes with lifecycle)
Explanation
Bacteriostatic refers to an agent that inhibits the growth or reproduction of bacteria without killing them. This means that the agent interferes with the lifecycle of bacteria, preventing their multiplication and spread. Unlike bactericidal agents that directly kill bacteria, bacteriostatic agents only temporarily halt bacterial growth, allowing the body's immune system to eventually eliminate the bacteria. Bacteriostatic agents are commonly used in medical treatments to control bacterial infections and prevent the further spread of bacteria in the body.

Larvae of several fly species
12.
Enzymes that reduce the effectiveness of certain antibiotics;
beta-lactamase I is penicillinase; beta-lactamase II is cephalosporinase
Explanation
Beta-lactamase is an enzyme that reduces the effectiveness of certain antibiotics. It is specifically responsible for breaking down the beta-lactam ring structure found in these antibiotics, rendering them ineffective against bacteria. There are different types of beta-lactamases, such as beta-lactamase I (penicillinase) and beta-lactamase II (cephalosporinase), which are named based on their ability to break down specific types of antibiotics.
13.
Loss of feeling or sensation in a large area (region) of the body after injection of an anesthetic agent into the spinal canal or around peripheral nerves
Explanation
Regional anesthesia refers to the loss of feeling or sensation in a large area of the body after the administration of an anesthetic agent into the spinal canal or around peripheral nerves. This technique is commonly used during surgeries or medical procedures to numb a specific region of the body, allowing for pain relief and immobilization. Regional anesthesia can be achieved through various methods, such as epidural anesthesia, spinal anesthesia, or peripheral nerve blocks. By blocking the transmission of nerve signals, regional anesthesia helps in minimizing pain and discomfort for patients undergoing surgical interventions.
14.
A disease or syndrome characterized by an overabundance of corticosteroid hormones
Explanation
Cushing's Disease is a medical condition characterized by the excessive production of corticosteroid hormones in the body. This can occur due to various reasons, such as the presence of a tumor in the pituitary gland or the prolonged use of corticosteroid medications. The overabundance of these hormones can lead to a range of symptoms, including weight gain, high blood pressure, muscle weakness, and mood changes. Treatment options for Cushing's Disease may include surgery, radiation therapy, or medications to lower the production of corticosteroids.
15.
An agent produced by a microorganism or semisythetically that has the ability to ihibit the growth of or kill micoorganisms
Explanation
An antibiotic is a substance produced by a microorganism or created through a semi-synthetic process that can inhibit the growth of or kill microorganisms. It is an agent that is specifically designed to target and eliminate bacteria, fungi, or other harmful microorganisms. Antibiotics work by interfering with the essential processes or structures of these microorganisms, preventing their growth or causing their death. They are commonly used in medicine to treat bacterial infections and have played a crucial role in saving countless lives since their discovery.
