Answer:
6 in total; 3 viable and 3 non-viable
Explanation:
Robertsonian translocation is one of the types of structural alteration in chromosomes, in other words, a rearrangement between chromosomes, which can occur between five pairs of acrocentric chromosomes (chromosomes with the centromere close to the end of one of the "arms"): 13, 14, 15, 21 and 22.
An individual who has Robertson's translocation between chromosomes 14 and 21 generally has only 45 chromosomes. 
In addition, a carrier of this type of translocation can theoretically produce 6 types of gametes, however 3 of them are not viable.
As for the three remaining gametes: One is normal, and among the other two, one is balanced and the last is unbalanced.
So, theoretically, when combining a normal gamete, the probability of a child with down syndrome being born through these conditions is 1/3 (considering that the probability of producing a certain type of gamete is equal for the three types).

b. Angiosperm
Explanation:
Acorn is the fruit of oak tree. It is a nut and bears only one seed.
Since the scientist finds that the fruit produced on the tree is a nut then it is obviously an angiosperm because:
The only groups of seeded plant are Gymnosperms and Angiosperms.
Gymnosperms produce cones and have naked seed.
The seed produced within a fruit is a characteristic of angiosperm.
