Q:

Blood group compatibility for marriage?

Answer

Matching blood group before marriage is important. This is to prevent Rh incompatibility. Rh incompatibility can lead to erythroblastosis fetalis (Hemolytic disease of the newborn-HDN). Fetal RBC gets destroyed & newborn may get severe anaemia, jaundice. This jaundice is more severe than Physiological jaundice ( which is the most common and will usually resolve on its own).


 


In very severe form, a fetus may die due to heart failure. This is mediated by the antigen-antibodies reaction. Transfer of maternal antibodies across the placenta occurs. This happens when Rh +ve man marries Rh-ve lady.


  


So Rh +ve man should try to avoid marrying Rh-ve lady.


 


Matching blood groups for marriage ::


Boy : A = Girl : A & AB 


Boy : B = Girl : B & AB 


Boy : O = Girl : O, A, B & AB 


Boy : AB = Girl : AB 


Boy : Rh+ve = Girl : Rh+ve 


Boy : Rh-ve = Girl : Rh+ve & Rh-ve.


  


Blood groups that do not match for marriage ::


Boy : A = Girl : O & B 


Boy : B = Girl : O & A 


Boy : AB = Girl : O, A & B 


Boy : Rh+ve = Girl : Rh-ve.

Read the passage carefully and choose the best answer to each question out of the four alternatives and click the button corresponding to it.


Dyslexia is a perceptual disorder often occurring in persons of normal, or even above average intelligence. The reader is unable to perceive correctly what is on a page. Letters and numbers often appear reversed: "b" seems to be "d","quite" is "quiet" and "from" is "form". The reader tends to leave out letters or words or insert words or letters that are not there. Vowel and consonant sounds may be confused. Many dyslexics are left­handed or able to write with either hand. They often confuse left and right. Learning to speak may also be delayed beyond infancy. The condition seems to be inherited. It may persist into adulthood. However, with early recognition and specialized approaches to teaching reading, most dyslexics can learn to read.

Some researchers believe that latent dyslexia may be aggravated by the way reading is taught. The modern whole­word, or look­and­say, method seems to be more of a hindrance to learning for dyslexics than it is for ordinary pupils. The phonetic method of teaching students to learn letters and sound them out appears to achieve better reading results. The problem of words that cannot be sounded out ­ such as rough, laugh or through ­ is not solved by phonetics. These words must simply be memorized. However, for children with dyslexia the problem can be compounded by the failure of parents or teachers to recognize the condition. This can easily lead to emotional problems for dyslexic children, who cannot understand their failure to keep up with their classmates.


Dyslexia may ___________

A) be noticed during infancy B) last till childhood
C) persist into adulthood D) end when one goes to school
