Arteries carry oxygenated blood away from the heart and typically have ________________ blood pressure. Veins carry deoxygenated
KatRina [158]
The correct answer is high, low.

Arteries are part of the circulatory system and are responsible for carrying blood away from the heart and around the body. The arterial blood is oxygenated and this process ensures that every tissue around the body will receive oxygen and nutrients through this blood flow.

Veins are also part of the circulatory system and are responsible for carrying the deoxygenated blood from the tissues back to the heart.

Venous pressure is much lower than the arterial pressure. More specifically, venous pressure ranges from 5 to 8 mmHg, while arterial pressure ranges from 15 to 30 mmHg.

Setler79 [48]

The correct order of steps in a gram staining procedure is:

(4) the specimen is treated with a stain called crystal violet.

(1) iodine is added as a fixative or mordant.

(3) the specimen is flushed with alcohol to dehydrate peptidoglycans and trap the stain.

(2) the specimen is treated with a stain such as safranin or fuchsin (a pink stain)

Gram staining is a common staining technique which helps to classify the bacteria into two categories: Gram positive and Gram negative. Gram positive bacteria appear violet in color and Gram negative bacteria appear to be pink. This color difference appears due to the difference in the bacterial cell walls.
