4 0

Answer:

are secreted from the glands of the endocrine system, they are specific in that each hormone causes a response in a specific target organ or group of cells, rather than on the body as a whole. Exocrine hormones are secreted via a duct into the blood and usually effect a distant organ or tissue.

Investigator Benton uses several methods to analyze hair samples found at the crime scene. He examines the physical features of
Diano4ka-milaya [45]

Answer:

Medulla.

By analyzing the DNA extracted from the hair follicle, the medullary index and the pattern of medulla in the hair samples obtained from a crime scene, an investigator can identify the owner.

Explanation:

The hair consists of follicle and shaft. The follicle is the part of the skin, where the hair grows and the hair shaft has three layers: an inner medulla,  a cortex, and an outer cuticle.

The morphology (physical characteristics) of hair provides a broad detail on the racial background of  an individual and an investigator can identify a  group of people who share similar  traits. But the hair without follicle cells attached to it, cannot  be used to identify a specific individual. If the follicle of a hair is present, then it can lead to individual identification by DNA analysis. Also the medulla of animals is larger than that in the humans. By comparing the medullary index (the ratio of the diameter of the medulla to the diameter of the entire  hair), it can be determined if the hair obtained from crime scene belongs to animals or humans. The macroscopic (length, color, and curliness) and  microscopic characteristics ( pattern of the medulla, pigmentation of  the cortex, and types of scales on the cuticle) of the hair samples are studied during a crime investigation. If the entire hair follicle (follicular tag) is present in the hair samples found at the crime scene, the blood and tissue attached to  the follicle is extracted and analyzed using DNA profiling. DNA analysis of the hair follicle provides  an identification with greater accuracy than the hair shaft.

Cross-sectional views of an artery and of a vein are shown here. identify each on the lines
murzikaleks [220]
I believe, for the artery, they have, an open, circular lumen an a thick media
Veins on the other hand, have somewhat collapsed lumen and a thinner media. Arteries are blood vessels that carry blood out of the heart to other parts of the body, all arteries carry oxygenated blood except the pulmonary artery which carries deoxygenated blood from the heart to the lungs. Veins carry blood from other body parts to the heart, all veins carry deoxygenated blood except the pulmonary vein which caries oxygenated blood from the lungs to the heart.
