Sometimes, two atoms of the same element have different numbers of neutrons. What is this known as? Valence electrons Orbits Rad
2 answers:
Answer:
Isotopes
Explanation:
<em>Atoms of the same element sometimes have different forms just as we have plants of the same species having different varieties. These atoms usually have the same number of protons in their nuclei but different number of neutrons. They are referred to as isotopes. </em>
A good example of atoms of the same element having different number of neutrons is and
. Both atoms have 6 protons but while the latter has 6 neutrons, the former has 8 neutrons.
Valence electrons, orbits and radiation do not come close as atoms of the same elements with different neutrons.
The correct answer is Isotopes.

Answer:
In humans, blood group is determined by three alleles ,
, and
.
and
are co-dominant whereas
is recessive to other two.
Thus, if a person with blood group O produces offspring with blood group B then the other parent must contain allele.
The genotype of other person can be ,
, or
.
There is only one condition in which the person can have offspring with blood group O that is, when the other parent is .
In this condition, the probability of an offspring to have blood group O is 50%.
In other conditions, the probability of an offspring to have blood O is 0%.
