What are three possible ways a new gene inserted into cells using gene therapy could improve a persons health? a-it could blocks mutated gene from working b-it could code for proteins that work the way they are supposed to c-it could stop cancer cells from growing d-it could change viruses so that they can not make people sick someone

A-it could blocks mutated gene from working

B-It could code for proteins that work the way they are supposed to

C-It could stop cancer cells from growing

Explanation: it said three. Hope this helps.

answer: the correct answer is 1.

explanation: there are various process in which a radioactive nuclei decays:

1) alpha decay: in this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. the mass number is reduced by 4 units.

2) electron capture: in this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. simply, a proton and an electron combines together to form a neutron. mass number does not change in this process.

3) gamma ray emission: it is a decay process in which an unstable nuclei gives excess energy by a spontaneous electromagnetic process. this decay releases . this process does not change the mass number.

4) positron emission: it is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. this is also known as -decay. in this the mass number remains same.

from the above information, we see that only alpha-decay is producing a change in the mass number of the nucleus.

when it gains or loses electrons
