about twenty however there is a great amount of variance in this as certain organisms use some that others do not. At most twenty-six.

Living organisms are made up of cells, which are the basic structural and functional unit of life. The number of cells in a living organism can vary greatly depending on the organism's size and complexity, ranging from trillions in humans to just a single cell in some microorganisms. Each cell contains various elements such as carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur, which are essential for the organism's survival and functioning.
Most elements are required by some living things, somewhere - there's worms on the sea-bed that synthesise their nutrients from minerals venting from the sea floor, archaea that consume arsenic for respiration, all kinds of weird things like that. In terms of humans, we're talking carbon, hydrogen, oxygen, calcium, phosphorous, magnesium, sodium, iron, at the least - and there may be a few I've missed off that list.

Viruses are considered non-living because they are not cells. They do not exhibit some characteristics of life such as reproduction and growth.
Living things are made up of different elements such as carbon, hydrogen, oxygen, and nitrogen. The number of atoms in living organisms can vary greatly depending on the size and complexity of the organism. However, it is estimated that there are trillions of atoms in a single cell.
Living organisms have characteristics such as growth, reproduction, metabolism, response to stimuli, and adaptation to the environment. Non-living things lack these characteristics and do not exhibit processes such as growth or reproduction.
The number of genes it has.
The bacterium Mycoplasma genitalium has one of the smallest genomes of any known free-living organism, with around 525 genes. It is thought to have the smallest number of cells required for a functional, self-replicating organism.
There is no such number, depending on the organism the number of chromosomes varies from 1 to about 30,000,000!
DNA provides the information necessary to take a number of lifeless chemicals and turn them into a living system.
DNA provides the information necessary to take a number of lifeless chemicals and turn them into a living system.
Living things primarily consist of a few main elements (carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur), while the periodic table contains over 100 elements. The main elements found in living things make up the bulk of their composition, with other elements present in smaller quantities or roles.
The reproductive cells of an organism each contribute half of the required genetic material to create the offspring. This means that each reproductive cell has 1n, while the organism has 2n chromosomes.
yes although the number of cells in an organism may vary depending on whether it is a unicellular or multicellular organism.

Anywhere from one to billions. Every organism is different, and most of the time it's impossible to know the exact number of cells. Also, the number of cells is not constant at all times for most organisms.
