<u>Answer:</u> The order of decreasing dry mass in human cells is C→O→H→N
<u>Explanation:</u>
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 need help to??????????? help me
Answer:
B
Explanation:
Chemoreception is a physiological process where an organism reacts to a chemical stimulus in their environment.
Pheremones are chemical substances that organisms release into their environments as a form of communication.
Pheremones bind to chemoreceptors which causes a response once the nervous system of the bee has analyzed and identified the chemical substance. The bee can then react with further communication.
Answer: Adult stem cells are undifferentiated cells, found throughout the body after development, that multiply by cell division to replenish dying cells and regenerate damaged tissues. Also known as somatic stem cells, they can be found in juvenile, adult animals, and humans, unlike embryonic stem cells.
