Cross-sectional studies are used to analyze a population's illness burden or health requirements, and they are especially effective in informing health resource planning and allocation. A cross-sectional survey can be used to measure the burden of a certain disease in a defined population.

Cross-sectional studies capture a single point in time, gathering data from a research group at a particular point. This is often done with a single survey, questionnaire, or observation.

lesya [120]

<u>Answer: </u>

The principle of federalism refers to the distribution of power between the central and the state government.

<u> Explanation:</u>

The principle of federalism is a mode of a political organization or a basic principle in any country that unites the different states of the country to the central government and at the same time allows the different sates to maintain their individuality and integrity.

It is a 'division of power' among the central government and the other states of the country.

By distributing the powers among the states or by spreading the powers equally into the state governments, the ones who frame the constitution primarily build a 'stronger and a functional country government' while preserving the 'existing states' and the concept of 'local state government'.
