True, individuals with familial Down Syndrome are trisomic and have 47 chromosomes. This occurs when there's an extra copy of chromosome 21 as a result of a parent carrying a rearranged chromosome, or translocation.
True. Individuals with familial Down Syndrome are indeed trisomic, which means they have an extra copy of a certain chromosome. In the case of Down Syndrome, there's an extra copy of chromosome 21, resulting in a total of 47 chromosomes instead of the usual 46. People inherit this condition through familial Down Syndrome when one parent carries a rearranged chromosome, referred to as a translocation. In this type of Down syndrome, there are three copies (i.e., trisomic) of chromosome 21.

Answer:
Alpha particles are usually produced by alpha decay which consisted of two protons and two neutrons.
They are identical to the nucleus of helium-4.
The alpha particle is represented as α or α²⁺. In addition, as it is identical to nucleus of helium, it is also represented as He²⁺.
As it only posses two protons and two neutrons but no electrons, the overall charge of alpha particle is +2.
The mass number of an element refers to the total number of neutrons and protons in the nucleus. Hence, the mass number of alpha particle would be 4
