Why is a parent usually a better match for transplanted tissue to a donor than a random individual of the same species?
s344n2d4d5 [400]

Answer: For decreased chances of rejection

Explanation:

The three higly polymorphic MHC 1 genes in human beings are HLA-A, HLA-B and HLA-C.

These determine the compatibility of the organ or tissue in the recipient's body each by the help of many alleles that segregates in a population.

There are very less chances that a random chosen donor will match the a recipient six allele genotype.

This is the reason parent  may be the best donor for organ transplantation or tissue transplantation.

Which equation satisfies the law of conservation of matter?
BartSMP [9]

Answer:

The correct answer is A. 3O₂ + 2Al → 2AlO₃

Law of conservation of mass states that mass can nether be created nor destroyed in a closed system or chemical reaction i.e. the total mass of the matter always remains the same throughout the chemical or physical change.

For example, in the given reaction 3O₂ + 2Al → 2AlO₃ the total mass of the reactants is equal to the total mass of the product.

Mass of oxygen = 16 x 3 = 48 AMU

Mass of aluminium = 2 x 27 = 54 AMU

Total molecular mass of the reactants = 102 AMU

Total molecular mass of the product = 2 x 27 + 6 x 8 = 102 AMU.

Hence, the total mass of the matter remains the same.
