Answer 1

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.

# Hydrogen # Lithium (rare)

# Boron # Carbon # Nitrogen # Oxygen # Florine # Sodium # Magnesium # Silicon (rare)

# Phosphorus # Sulfur # Chlorine

# Potassium # Calcium # Chromium (rare) # Manganese

# Iron # Copper # Zinc # Arsenic (rare) # Selenium (rare) # Bromine # Iodine # Strontium (rare) # Molybdenum

Answer 2

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.

Answer 3

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.
