a scientist is examining the role of an element found in fatd and cabohydrates of living things this element makes up 65% of human body mass which statement describes the element he is studying?

The question is incomplete as the group of choices are not provided however the correct group of choices are given as follows:

He is studying oxygen, which can also be found in proteins.

He is studying oxygen, which is the most abundant element in the atmosphere.

He is studying nitrogen, which can also be found in proteins.

He is studying nitrogen, which is the most abundant element in the atmosphere.

The correct answer is - He is studying oxygen, which can also be found in proteins.

Explanation:

Human body is comprises of various type of molecules and elements such as fats, protein, carbohydrates and many other elements. Carbohydrates and fatty acids are are made up of 3 major elements carbon, hydrogen and oxygen.

Oxygen is an essential element with 65% of all elements found in human body it shows great affinity with proteins. Oxygen binds with hemoglobin then transferred to the through out the body.  The oxygen is also one of the elements found in proteins with other elements like nitrogen, hydrogen and carbon.

Thus, the correct answer is - He is studying oxygen, which can also be found in proteins.

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
