Answer:
In biology, cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells.
The three tenets to the cell theory are as described below: All living organisms are composed of one or more cells. The cell is the basic unit of structure and organization in organisms. Cells arise from pre-existing cells.
Explanation:
In biology, cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all organisms and also the basic unit of reproduction. With continual improvements made to microscopes over time, magnification technology advanced enough to discover cells in the 17th century. This discovery is largely attributed to Robert Hooke, and began the scientific study of cells, also known as cell biology. Over a century later, many debates about cells began amongst scientists. Most of these debates involved the nature of cellular regeneration, and the idea of cells as a fundamental unit of life. Cell theory was eventually formulated in 1839.
The membrane also plays a vital function in preventing things from getting in or leaving the cell, and the second major function is that it is a factor in cell communication and cell recognition.
The correct answer is:
nucleic acids
Explanation:
Nucleic acids are biopolymers, or humble biomolecules, necessary for all known methods of life. They are formed of nucleotides, which are monomers comprised of three components: a 5-carbon sugar, a phosphate group, and a nitrogenous base..Nucleic acids are the basic unit of heritage, they develop all the genetic element of living things.This genetic information defines how individual cells and entire organisms grow and function
