Answer:
Proton and neutron.
Explanation:
The atoms consists of three sub atomic particles - proton electron, and neutron. The proton and neutron are present inside the nucleus and electrons revolve around the nucleus.
The number of proton is equal to the number of electron in the neutral stage of atom. The atomic mass of an element can be calculated by the sum of number of neutrons and the number of protons. Hence, the subatomic particle - proton and neutron contribute to the mass of hydrogen.
Thus, the correct answer is option (b) and (d).
Answer:
They could have all four type phenotype that are A, B, AB, and O
Explanation:
If the man has A blood group and the woman has B blood group then the genotype of man can be IAIA or IAi and the genotype of woman can be IBIB or IBi.
IA i
IB IAIB IBi
i IAi ii
So if the genotype of the parents are IAi and IBi then out of four offspring one could have AB blood group, second could have B blood group, third could have A blood group and fourth could have O blood group as shown in the cross above.
