Which is the negatively charged particle located outside the nucleus of an atom?
question 25 options:

electron

neutron

silicon

proton

electron

Explanation: An atom is made up of three fundamental particles: electron, proton and neutron. Electrons have negative charges, protons have positive charges while neutrons have no charge. The number of electrons is equal to the number of protons thus making an atom electrically neutral. Protons and neutrons are located inside the nucleus of an atom while electrons are located outside the nucleus where they revolve round the nucleus in their orbits.

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
