All the different habitats in our world make up biodiversity ecosystem diversity genetic diversity species diversity

The correct answer is biodiversity.

Explanation:

Biodiversity is defined as the system which refers to the variety of life present on Earth. It measures the variation at genetic, ecosystem and species level.

Ecosystem diversity is defined as the system which deals with the variation in ecosystem with geological location and its impact on human lifestyle and environment.

Genetic diversity is defined as the diversity which happens within the species. It is basically the total number of characteristics of genes which can makeup a genetic specie.

Species diversity is defined as diversity which tells us the total number of different species existing in a given community.

Hence, the correct answer is biodiversity.

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.
