  3. 4 chambered stomach

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
The digestive system of cow is made up of oesophagus, 4-chambered stomach and small and large intestine. The food is passed through oesophagus from mouth to the stomach. The cow has 4-chambered stomach that digest and process the food and then pass it on the small and large intestine for absorption.
So the correct answer is 'All of the above'.

  3. Dysteleology

  4. Tricology
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
A- Food combining (also known as trophology) is a term for a nutritional approach that advocates specific ingestion and combinations of foods as central to good health and weight loss.
B- Teratology is the medical discipline that focuses on birth defects and congenital abnormalities. Most teratological professionals provide consultative services to pregnant women, or engage in complex research. 
C- Absence of purpose in nature especially as manifested in rudimentary or nonfunctional structures.
D- Trichology is the branch of dermatology concerned with the health of hair and scalp. Trichology helps in diagnosis of the causes of hair fall, hair breakage, hair thinning, miniaturization of hairs, diseases of the scalp and treat the diseases.
So, the correct option is 'Trophology'.

  1. <p>Female Anopheles</p>

  2. <p>Female Aedes</p>

  3. Male Anopheles

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Dengue fever is a mosquito-borne tropical disease caused by the dengue virus. Dengue is spread by several species of a mosquito of the female Aedes type, principally Aedes aegypti. Symptoms include high fever, headache, vomiting, muscle and joint pains, characteristic skin rash, bleeding, low levels of blood platelets and blood plasma leakage. So, the correct answer is 'Female Aedes'.

Aedes spreads 

  1. Malaria

  2. Dengue

  3. Sleeping sickness

  4. Kala-azar
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • Dengue fever is a mosquito-borne tropical disease caused by the dengue virus. Dengue is spread by several species of a mosquito of the  Aedes Type, principally A.aegypti.
  • Symptoms typically begin three to fourteen days after infection.[2] This may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin rash
  • Arbovirus is an informal name used to refer to any viruses that are transmitted by arthropod vectors. As dengue is transmitted by an arthropod vector(mosquito) its causative organism is called arbovirus. Hence Aedes spreads Dengue'.
  • So,the correct answer is 'Dengue'.

An antibiotic yielding fungus amongst the following is

  1. Cladonia

  2. Parmelia

  3. Penicillium

  4. Aspergillus
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Penicillin sometimes abbreviated PCN or pen is a group of antibiotics derived from Penicillium fungi. Penicillin antibiotics were among the first drugs to be effective against many previously serious diseases, such as bacterial infections caused by staphylococci and streptococci. Penicillins are still widely used today, though misuse has now made many types of bacteria resistant.

Thus, the correct answer is option C.

Tourniquet test is for the diagnosis of 

  1. Diphtheria

  2. Break bone fever

  3. AIDS

  4. Hepatitis A
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Tourniquet test determines the capillary fragility. It is a clinical diagnostic method to determine a patient's haemorrhagic tendency. It assesses fragility of capillary walls and is used to identify thrombocytopenia (reduced platelet count). This test is used for the diagnosis of dengue fever, also called as breakbone fever.
Therefore, the correct answer is option B.

Which of the following is an incorrect match?

  1. Disease - Pulmonary, Causative organism - Bacterium, Mode of transmission - Airborne and droplet infection

  2. Disease - Gonorrhoea, Causative organism - Bacterium, Mode of transmission - Through sexual contact

  3. Disease - Dengue, Causative organism - Virus, Mode of transmission - Through vector Culex mosquito

  4. Disease - Ringworm, Causative organism - Fungus, Mode of transmission - From clothes of infected person
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Dengue is transmitted by the bite of a mosquito infected with one of the four dengue viruses. It is a febrile illness that affects infants, young children and adults with symptoms appearing 3-14 days after the infective bite.
Dengue is not transmitted directly from person-to-person and symptoms range from mild fever, to incapacitating high fever, with severe headache, pain behind the eyes, muscle and joint pain, and rash. There is no vaccine or any specific medicine to treat dengue. People who have dengue fever should rest, drink plenty of fluids and reduce the fever using paracetamol or see a doctor. Dengue is transmitted by several species of mosquito within the genus Aedes, principally A. aegypti.
Severe dengue (also known as dengue hemorrhagic fever) is characterized by fever, abdominal pain, persistent vomiting, bleeding and breathing difficulty and is a potentially lethal complication, affecting mainly children. Early clinical diagnosis and careful clinical management by trained physicians and nurses increase survival of patients.

Which of the following diseases is caused by a virus?

  1. Typhoid

  2. Cholera

  3. Influenza

  4. Diphtheria
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Common viral diseases include: chickenpox, flu, influenza, herpes, human immunodeficiency virus (HIV/AIDS), human papilloma virus (HPV), mumps, measles and rubella. Bacteria cause disease by secreting or excreting toxins (as in botulism), by producing toxins internally, which are released when the bacteria disintegrate (as in typhoid), or by inducing sensitivity to their antigenic properties (as in tuberculosis). Other serious bacterial diseases include cholera, diphtheria, bacterial meningitis and syphilis.

The disease not transmitted by house-fly is 

  1. Dysentery

  2. Cholera

  3. Enteric fever

  4. Dengue fever
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

House flies are strongly suspected of transmitting at least 65 diseases to humans, including typhoid fever, dysentery, cholera, poliomyelitis, anthrax, tularemia, leprosy and tuberculosis. Flies regurgitate and excrete wherever they come to rest and thereby mechanically transmit disease organisms. Dengue is transmitted by mosquito.
