Answer:
Fraction-of-occurrences of 115In isotope 
Explanation:
As we know  weight of 113 In  isotope is equal to the sum of product of fraction-of-occurrences of two constituents isotopes and their atomic weight
  ------(1)
 ------(1)
As we know sum of fraction-of-occurrences of two constituents isotopes is equal to one. 
 ---------(2)
---------(2)
Substituting the given values in equation 1, we get 

Substituting this value in equation 2 we get -

Answer:
The correct answer is option d, that is, endocytosis. 
Explanation:
A procedure in which a component gains entry within the cell without getting passed through the cell membrane is termed as endocytosis. In this process, the cell captivates the substances from the external of the cell by engulfing and combining them with its plasma membrane.  
The process is further differentiated into three distinct kinds. These are phagocytosis, pinocytosis, and receptor-mediated endocytosis.  
 
        
             
        
        
        
Answer:
A.
Explanation:
Patient 1 has Type A blood because agglutination occurs due to reaction with anti-B. We know that A blood group has antigen A and it is anti-B means that they attack on B type of blood cells while on the other hand, B blood group has antigen B and it is anti-A means that they will attack on the A type blood cells upon mixing. So according to the chart, there is nothing happens by reaction of the blood with anti-A whereas agglutination occur by reaction with anti-B so we can say that the patient has type A blood.
