Which elements are common to all organisms? check all that apply.

1.sodium
2.oxygen
3.sulfur
4.hydrogen
5.iron
6.phosphorus

There exist chemical elements that are found in a greater quantity in the living organisms. They are:

- Oxygen: the most abundant element in living organisms. Humans is composed in a 65% of it.

- Carbon: the basis of all life on Earth. Living organisms are also refered to as carbon-based life forms.

- Hydrogen: the simplest element containing one proton and bonding easily with other elements.

- Nitrogen: composes around 80% of air on Earth. Very important in the plant life.

- Sulfur: component of cysteine and methionine, essential amino acids for living organisms.

- Phosphorus: used in the formation os phospholipids  a major component of cell membrane of living organisms.

well, paralell is parallel. i am providing links to .

hope this !

a series circuit is one with all the loads in a row. there is only one path for the electricity to flow. if this circuit was a string of light bulbs, and one blew out, the remaining bulbs would turn off.

unlike in series circuits, a charge in a parallel circuit encounters a single voltage drop during its path through the external circuit. the current through a given branch can be predicted using the ohm's law equation and the voltage drop across the resistor and the resistance of the resistor.

a parallel circuit has certain characteristics and basic rules: a parallel circuit has two or more paths for current to flow through. voltage is the same across each component of the parallel circuit.
