James has a hemoglobin measurement of 16 g/100 ml blood. this is
a. within the normal range
b. above normal
c. abnormally low
d. normal only if james is an infant

A. Within the normal range.

Explanation:

Hemoglobin is a protein molecule found in the red blood cells. It's primary function is to carry oxygen from the lungs to the tissues and carry carbon dioxide out of the tissues.

For men, the normal range for hemoglobin in the blood is between 14 g/100ml and 18 g/100ml. A low hemoglobin count could be an indication of anemia, while a high count could be attributed to lifestyle choices.

answer; the above statement is (true);

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
