Answer;
-COOH
Explanation;
The carboxyl group includes both a keto oxygen and a hydroxyl group; Carboxyl groups are weak acids, dissociating partially to release hydrogen ions. The carboxyl group (symbolized as COOH) has both a carbonyl and a hydroxyl group attached to the same carbon atom, resulting in new properties.

When an ophthalmologist uses an ophthalmoscope to look into your eye he sees the following view of the retina
In the center of the retina is the optic nerve, a circular to oval white area measuring about 2 x 1.5 mm across. From the center of the optic nerve radiates the major blood vessels of the retina. Approximately 17 degrees (4.5-5 mm), or two and half disc diameters to the left of the disc, can be seen the slightly oval-shaped, blood vessel-free reddish spot, the fovea, which is at the center of the area known as the macula by ophthalmologists.
Answer:
Cubic centimeters is the correct unit for measuring the volume of a solid. By contrast, liters are the correct units for measuring the volume of a liquid. For substances such as water, with a specific gravity of 1, each cubic centimeter of the liquid is equal to 1 milliliter of the liquid.
Explanation:water from the combined volume of the water and the solid. 6. The result is the volume of just the irregular shaped solid. The volume of just the water is 50 mL. After the small rock is placed in the cylinder the volume rises to 70mL. Subtract the 50 mL of water from the combined volume of 70 mL. The rock has a volume of 20 mL.
It is unlikely your vitamin needs are significantly increased above the Dietary Reference Intakes (DRI) and a vitamin supplement may not be necessary, but a dietary assessment may reveal vitamin deficiencies is the best message for the athlete.
