Analytical observational studies

Observational (observational) researches are called

research types based on the observation and analysis of the diseases that occur in natural conditions and the

environment where they occur.

Cross Section Study 

Cross-sectional study is based on the principle of detecting diseases or infections at a certain time.

Longitudinal study

The study based on periodic observations in the

population, which is continued and examined in a certain time period, is generally called longitudinal work.

Case-control study

In case-control studies, workgroups are divided into sick and non-sick animals.

In these groups, the presence or frequency of a particular determinant is investigated.

Cohort study

The frequency of disease occurrence is examined in

groups that are exposed and not affected by a certain effect.

Model study

Disease development, spread and transmission related developments, that is, the dynamic structure of

diseases or disease control strategies can be studied using mathematical methods.

It is called studying, modeling or modeling, which obtains simulations that make natural developments in disease or disease control become mathematical equations.

Embedded in the thylakoid membranes (commonly called lamellae) are the photosynthetic pigments and the enzyme complexes that carry out the light reactions and ATP synthesis

In the light reactions, chlorophyll and other pigments of photosynthetic cells absorb light energy and conserve it as ATP and NADPH; simultaneously, O2 is evolved.. In the
