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.  

endo:

regulates body hormones, aldosterone, vasopressin

neural:

signal, regulates body using electric signals, reflex

endo has to do with hormones; aldosterone and vasopressin are both hormones. i also had this question and got it right : d

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
