The study of which structure was instrumental in the formulation of the modern cell theory?
plant cell
animal cell
cell membrane
dna molecule

The cell is the fundamental unit of structure and function in all living organisms. -The modern version of the Cell Theory includes the ideas that: Energy flow occurs within cells. Heredity information (DNA) is passed on from cell to cell.

The correct answer is DNA molecule.

Explanation:

On the basis of cell theory, all the living things are made up of one or more cells. All the living cells originate from the pre-existing cells by differentiation. The cell is the basic unit of composition and function in all the living species.  

On the basis of the new version of the Cell theory, the flow of energy takes place from cell to cell, all the cells exhibit identical chemical structure, and heredity information (DNA) is passed from one cell to another. Thus, the study of the DNA molecule was instrumental in the development of modern cell theory.  

correct answer: biotic and abiotic limitations

carrying capacity is defined as the total number of an organism who can be supported in a given area within the natural resources limit and without harming or degrading the natural, economic or the cultural environment present for the future generations.

carrying capacity is determined by the limiting factors, which are known to affect the natural resources available. it may include water, nutrients, minerals, space, light etc.

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression
