C Correct answer
Explanation

Sexually transmitted infections are more common in 15-24 years age group. Gonorrhoea, syphilis, genital herpes, chlamydiasis, genital warts, trichomoniasis, hepatitis-B and AIDS are some of the common STDs. Haemophilia is sex-linked recessive disease, which show its transmission from unaffected carrier female to some of male progeny. Sickle cell anaemia is an autoimmune linked recessive trait in which both the partners are carrier for the gene

So, the correct answer is 'Chances of a five years old boy contracting a STD are very little',

E Correct answer
Explanation

Diseases or infections which are transmitted through sexual intercourse with infected persons are collectively called sexually transmitted diseases(STDs).

Examples- HIV leading AIDS, gonorrhoea, Syphilis, Chlamydiasis, Genital herpes, Genital warts, Hepatitis-B, Trichomonasis, Enterobiasis, Scabies, Candidiasis.
Myasthenia gravis is a chronic autoimmune neuromuscular disease that causes weakness in the skeletal muscles, which are responsible for breathing and moving parts of the body, including the arms and legs. In this condition, antibodies, which are proteins that normally attack foreign, harmful substances in the body, attack the neuromuscular junction.
So, the corrrect answer is 'Myasthenia gravis'.

A Correct answer
Explanation
In haemophilia, the blood does not clot as it should. Haemophilia is normally an inherited disorder. It happens because of a defect in one of the clotting factor genes on the X chromosome. Haemophilia tends to occur in males since the gene can be passed from mother to son. Males typically lack a second X chromosome so they are unable to make up for the defective gene. Most females have XX sex chromosomes while most males have XY sex chromosomes.
Haemophilia B, also known as "Christmas disease," occurs when a person lacks clotting factor IX.
So, the correct answer is 'Christmas disease'.

Assertion:  Males suffer from sex-linked disorders more often than females.

Reason: Sex-linked traits are mostly governed by recessive genes.

  1. If both the assertion and the reason are true and the reason is a correct explanation of the assertion

  2. If both the assertion and reason are true but the reason is not a correct explanation of the assertion

  3. If the assertion is true but the reason is false

  4. If both the assertion and reason are false

  5. If the assertion is false but reason is true
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Males have only one X chromosome, so any recessive sex-linked gene on that chromosome will be expressed. Females have two X chromosomes, so they must inherit two copies of the recessive gene to express the trait, making it much rarer for them.

Which one of the following groups includes all sexually transmitted disease?

  1. AIDS, Syphilis, Cholera

  2. HIV, Malaria, Trichomoniasis

  4. Hepatitis-B, Haemophilia, AIDS
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

All of the diseases like AIDS, Gonorrhoea, hepatitis- B, chlamydiosis, and syphilis are sexually transmitted diseases. While cholera, malaria, hemophilia are water-borne, parasitic and Mendelian disorders respectively.

So the correct option is 'Gonorrhoea, hepatitis- B, chlamydiasis'.

  2. Biological control method

  3. Bio accumulation method

  4. Bio magnification method
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

There are different forms of pest control methods for the elimination of the insects and pests. If a farmer introduces the organisms or pests which can act on the other harmful pests, known as the biological control method. This method involves the use of living organisms for the eradication of the insects in the farm which destroy the crops. The lizards feed on the insects and protect the crops. 

Thus, the correct answer is option B.

Hence, the correct answer is option C.

  2. It shows only tip growth

  3. It is composed of three non-cellular zones

  4. It shows radial cytoplasmic streaming
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The movement of pollen tube towards embryosac though style is chemotactic as it secrets pectinases and other hydrolytic enzymes to create a passage for its entry into style .
