The body of each organism is organized in a certain manner. which of the following shows the organization of the body from the simplest level of the most complex level?

As the options for the question are not given, let's answer the question generally.

Explanation:

The organization of a body from the simplest level to most complex level is as follows:

Cells: Cells can be defined as the basic unit of life.

Tissues: Group of cells which work together to perform  task are known as tissue.

Organ: group of tissues work together to form an organ.

Organ system: Different organs work together to form an organ system.

Organism: The organ systems work together to make up a whole organism.

genetics is the study of how dna works, the methodologies defining the new recent technologies allow scientist to have a panoramic view of the entire dna landscape, especially how genomes interact with their environment, including off course, factors outside their organisms.

thus is very possible the existence of both scenarios, where populations of isolated individuals have different genetic traits, and share traits related to genetic mutation, due rats can easily travel overseas using human transport channels. so scientists could get a vast number of data, including human interaction, evolution of rodents, health development, spread of infections, development of new organisms, how genomes evolve in different environments and so on.
