Show answer
Correct Option: A
Explanation:
Gout is a form of arthritis and also known as gouty arthritis. It is characterized by severe pain in joints. There is deposition of crystals of uric acid in the joints due to which inflammation, swelling and severe pain occurs in joints. This occurs when high levels of uric acid are there in blood. Uric acid is formed from the breakdown of purines. Hence, gout is a physical disease not a mental.
So, the correct answer is 'Gout'.

  1. Kalaazar

  2. Measles

  3. Meningitis

  4. Sickle cell anaemia

Show answer
Correct Option: D
Explanation:

A congenital disease, also known as a birth defect is a condition present at birth regardless of its cause. Birth defects may result in disabilities that may be physical, intellectual, or developmental. Sickle cell anaemia is a blood disorder which is typically inherited from person's parents.  It results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. This leads to a rigid, sickle-like shape RBC. Kala-azar, measles and meningitis are the diseases caused by pathogens.

So, the correct answer is 'Sickle cell anaemia'.

Which one of the following is a genetic disease?

  1. Scurvy

  2. Leukemia

  3. Goitre

  4. Haemophilia

Show answer
Correct Option: D
Explanation:
In Haemophilia, the blood fails to clot when exposed to air and even a small skin injury results in continuous bleeding and can lead to death from loss of blood.
Haemophilia is a well-known disorder which is a sex-linked recessive condition. The recessive X-linked gene for haemophilia shows characteristic Criss cross inheritance. A single recessive gene in man results in haemophilia whereas a woman needs two sets of genes for the same.
Hence, the correct answer is 'Haemophilia'

Correct Option: C
Explanation:
  • Psychosis is used to describe conditions that affect the mind, where there has been some loss of contact with reality. During a period of psychosis, a person’s thoughts and perceptions are disturbed and the individual may have difficulty understanding what is real and what is not.  
  • Symptoms of psychosis include delusions (false beliefs) and hallucinations (seeing or hearing things that others do not see or hear). Other symptoms include incoherent or nonsense speech, and behavior that is inappropriate for the situation. 
  • A person in a psychotic episode may also experience depression, anxiety, sleep problems, social withdrawal, lack of motivation, and difficulty functioning overall.
So, the correct option is 'Psychosis'

When children play bare footed in pools of dirty water and flood water, they may suffer from diseases like

  1. Leptospirosis and bilharzia

  2. Malaria, amoebic dysentery and leptospirosis

  3. Bilharzia, infective hepatitis and diarrhoea

  4. Guinea worm infection, elephantiasis and amoebic dysentery

Show answer
Correct Option: A
Explanation:
Leptospira is a genus of Spirochaete. It usually spreads from rodents to man. They are excreted in urine. Transmission to man may follow direct contact with urine, blood or tissue from an infected animal or exposure to a contaminated environment. Therefore, the epidemic may result from exposure to flood water contaminated by urine from infected animals. The spirochaete may enter through skin abrasions or even through intact mucus membranes of the mouth, oropharynx or oesophagus on swallowing.
Bilharziasis is the older name of Schistosomiasis. Portal of entry into man is through the skin when wading or swimming in water infested with cercariae larvae
So, the correct answer is 'Leptospirosis and bilharzia'

  1. Haemophilia A

  2. Haemophilia B

  3. Colour blindness

  4. Sickle cell anaemia

Show answer
Correct Option: A
Explanation:

Haemophilia A is a genetic deficiency in clotting factor VIII which causes increased bleeding and usually affects males. It is the X-linked recessive trait. 

Therefore, the correct answer is option A.

John, a male hemophiliac, marries Jane, a normal woman, and together they have four children, two boys (Mark and Mike) and two girls (Molly and Mary). None of the children display the symptoms of hemophilia. Mark, Mike, Molly, and Mary all marry normal individuals and have children. None of Mark's or Mike's children, male or female, display symptoms of hemophilia, but the sons of Molly and Mary all display symptoms of hemophilia while the daughters of Molly and Mary do not. Which of the following individuals are heterozygous for hemophilia?

zoology why do we fall ill health introduction to health health and its maintenance

  1. John, Mark, and Mike

  2. Mark, Mike, Molly, and Mary

  3. John and Jane

  4. Molly and Mary

  5. Mark and Mike

Show answer
Correct Option: D
Explanation:

Hemophilia is sex linked recessive disorder. Gene responsible for it present on X chromosome and only expresses in dominant state. Out of four children of john (hemophiliac male) and Jane (normal woman), both the girls Molly and Mary become heterozygous for hemophilia as they got hemophiliac X chromosome from father only, which they pass on to their children resulting sons with hemophilia expressed and daughters are either normal heterozygous for hemophilia. The boys Mark and Mike are normal as they don't get hemophiliac X chromosome from father and when they married with normal individuals, all their children would be normal. Thus, the correct answer is ' Molly and Mary.'

 A male hemophiliac, marries a normal woman, and they have four normal children, two boys (Mark and Mike) and two girls (Molly and Mary). Mark, Mike, Molly, and Mary all marry normal individuals and have children. The children (male and female) of Mark's or Mike's children were normal but the sons of Molly and Mary all display symptoms of hemophilia while their daughters do not.
Which of the following statement best explains the reason that Mark, Mike, Molly, and Mary do not display symptoms of hemophilia, even though their father, John, is a hemophiliac?

zoology why do we fall ill health introduction to health health and its maintenance

  1. Hemophilia is an X-linked disorder, and John can pass on only his Y chromosome.

  2. Hemophilia is an X-linked disorder and even though Molly and Mary received a hemophiliac X chromosome from father, mother gave them a normal X chromosome.

  3. Hemophilia is a Y-linked disorder and therefore cannot be displayed in females.

  4. Hemophilia is a Y-linked disorder and Mark and Mike must have received an X chromosome from John.

  5. Hemophilia is an X-linked disorder, and even though Mark and Mike received a hemophiliac X chromosome from John, Jane gave them a normal X chromosome.

Show answer
Correct Option: B
Explanation:
Out of this family, the only members that express this condition are males. This is a tip-off for X-linked disorders, which are more common in males because they have only a single X chromosome.
John’s genotype is X$^h$Y. He passed his Y chromosome to Mark and Mike; they also received a normal X from Jane, thus they do not have hemophilia, nor can they pass it on to their kids. Molly and Mary received X$^h$ from John but also received a normal X from Jane, thus they are carriers of hemophilia but do not display its symptoms.

Therefore, the correct answer is option B.
