Kathy has found she must consume 2000 cal a day to reach her health goals and she has been following this carefully, but leave me she had been feeling exhausted and dizzy. a workout machine alerted her that she is exercising and losing up to 600 cal a day. kathy did not factor this into her nutrition plan strategy should use to improve her habits a) stop exercising all together to balance the calories. b) dieting all together to balance the calories. c) change nothing until her body adjusts on its own d) we calculate the calories she needs to consume

Kathy should recalculate the calories ... as well as all of the other categories of essential nutrition ... that she should consume on a regular, daily basis. And You should reconsider the effectiveness of reviewing, proofing, and editing what you write, before posting it and expecting others to understand it and respond to it.

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.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
