Stretch marks are the result of tears in the integumentary layer that contains fibrous connective tissue, elastin, and collagen. what is this region of the integumentary system called? (a) subcutaneous layer (b) langerhan layer (c) epidermis (d) hypodermis (e) dermis

E; Dermis

Explanation:

Skin and its underlying tissue can be affected by excessive pressure. Stretch mark results when the dermis is stretched beyond its limits of elasticity, as the skin stretches to accommodate the excess pressure. Stretch marks usually accompany rapid weight gain during puberty and pregnancy.

The correct answer is; e. anaerobic threshold  

Explanation:

The Anaerobic Threshold (also called Lactate Threshold) is a period during exercise in which there is increased buildup of lactic acid levels within the muscles. This mechanism usually occurs when exercising with increased intensity during which anaerobic energy is highly produced than aerobic processes. This physiological mechanism causes an increase in the acidity of the muscle cells and influences the blood PH along with other metabolites in the body.
