Which choice ranks the elements hydrogen, carbon, nitrogen, and oxygen in order of decreasing dry mass in human cells a. o→c→h→nb. c→n→o→hc. o→h→c→nd. c→o→h→n

The order of decreasing dry mass in human cells is C→O→H→N

Explanation:

Dry mass of the element in human cells means the mass of elements which have lost all the water.

Human cells consist of many chemical elements. Some of them are: Carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P), calcium (Ca), sulfur (S), potassium (K), sodium (Na), chlorine (Cl), magnesium (Mg) and many more.

Most abundant element found in the human cells is carbon.

The composition of the dry mass of the elements in human cells are:

Carbon = 47 %

Oxygen = 30 %

Hydrogen = 9 %

Nitrogen = 8 %

Phosphorus = 3 %

Sulfur + Potassium + Calcium + Sodium + Chlorine + Magnesium = 2 %

Other elements = 1 %

The decreasing order of dry mass of elements in human cells is:

Hence, the order of decreasing dry mass in human cells is C→O→H→N

i don't know. the other person does though.

measuring physical properties lab reportinstructions: in the physical properties lab, you will test the physical properties of different building materials in order to pick the appropriate materials for a new home in tiny world. record your observations and test measurements in the lab report below. youwill submit your completed report.name and title: lyric lawton, mr.herbert, 10/13/17, physical properties lab. objective(s): i need to parvus build his house out of the right material, so he will stay cool in the mountains.hypothesis: if we use wood to build the roof of the house, then the temperature inside the house will remain cooler.if we use clay brick to build the walls and floors of the house, then the temperature inside the house will remain cooler.if we use aluminium to bring electricity into the home, then it will allow electricity to flow into the home at a faster rate.if we use iron to construct the latches on the windows and doors, then the magnetism will keep the latches secure.
