The man couldn’t have fathered the following child.
<u>Explanation:</u>
The blood grouping system in humans is called ABO blood grouping. The possible blood groups of humans are A,B,AB and O. ABO blood grouping is an example of co-dominance where both alleles of the ABO gene are expressed equally.
The ABO gene has 3 alleles. They are I^A,I^B and i. the alleles I^A,I^B are dominant over i. Person with the genotype I^A I^A and I^A i has the blood group A while a person having the genotype I^B I^B and I^B i has the blood group B. The person with the blood group will have the genotype I^A I^B.
Here the mother’s blood group is O which means her genotype is ii. The man’s blood group is AB which means his genotype is I^A I^B. The possible genotypes of the children are I^A i,I^A i,I^B i,I^B i with respective phenotypes A, A, B and B.
There is no possibility that the child can have the blood group O which means that the man could not have fathered the child.
The form of decomposition that is performed by decomposers is chemical decomposition. Details about decomposers can be found below.
<h3>What are decomposers?</h3>
Decomposers are any organism that feeds off decomposing organic material, especially such a bacterium or fungus.
Decomposers are a vital component of the ecosystem because they help in the recycling of nutrients or useful substances.
However, decomposers such as bacteria and fungi breakdown the constituent of decaying substances chemically by releasing degrading enzymes.

Sunburn (First-Degree Burns): A sunburn is skin damage from the sun's ultraviolet (UV) rays. Most sunburns cause mild pain and redness but affect only the outer layer of skin ( first-degree burn). The red skin might hurt when you touch it. These sunburns are mild and can usually be treated at home.
