Select all the correct answers. Two students are debating whether the water cycle is a biogeochemical cycle. Which two of the following statements serve as
evidence that the water cycle is a biogeochemical cycle?
New water is constantly being produced and added to the cycle.
Water interacts with living organisms but not geological features.
Water returns to its original state after completing the cycle.
Water changes form and phase throughout the process of the water cycle.
When water is contaminated, it cannot be reused.
Anything help!!!

B, C, E.

Explanation: I took the test and verifed with the test results.

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.
