Nucleic acids are composed of nucleotides. These nucleotides are in themselves made by nucleosides (purines and pyrimidines) bound to one, two, or three phosphate groups. Thus, the answer is D.
According to the image above, I believe the answer would be D. Water Quality!
Hope this helps you out!
Thanks! :)
I think its D living space speaking how islands are small and that have fruit,water,and sunlight because their just the characteristics of a island.
So your answer is D living space
When blood is drawn from a blood vessel in your arm, it is dark red. This color indicates that the blood was taken from the vein.
Why was my blood so dark when drawn?
Hemoglobin, a protein found in blood cells that enables the delivery of oxygen throughout the body, contains iron, which gives human blood its red color. However, the amount of oxygen in the blood affects the hue. Blood that contains a lot of oxygen will appear bright red. If blood is drawn from an artery that transports blood from the lungs to the rest of the body, this is typical.
Deoxygenated blood is contained in the veins, which carry blood back to the lungs from the body. Based on the light wavelengths they reflect, chemicals appear to our eyes in specific colors. As blue-green light is absorbed by hemoglobin attached to oxygen, red-orange light is reflected into our eyes, giving the appearance of redness. Because of this, when oxygen attaches to iron in the blood, the color turns brilliant cherry red. Blood is a deeper shade of red when it is not coupled to oxygen.

Biopsychologists who study the physiological correlates of psychological processes by recording physiological signals from the surface of the human body are often referred to as<u> psychophysiologists</u>.
In the field of psychology, psychophysiology or biopsychology can be described as the study of psychology that focuses on the physiological bases for psychological responses.
Physiological signals such as the heart rate, the muscular activity of the skeletal muscles, skin conductivity etc are recorded and their relation to a certain psychological response from a person is studied under psychophysiology by the psychophysiologists.
The combination of these two aspects i.e psychology and physiology shows that certain emotional or mental Reponses occur due to abnormalities in some physiological signal.
