Which of the following causes yellowing of the skin?
Jaundice is a condition in which the skin, whites of the eyes and mucous membranes turn yellow because of a high level of bilirubin, a yellow-orange bile pigment. Jaundice has many causes, including hepatitis, gallstones and tumors. In adults, jaundice usually doesn’t need to be treated.

What is the protein that reduces water loss at the skin surface is?
stratum basale. E) stratum granulosum. Answer: B. 15) The protein that reduces water loss at the skin surface is. A) eleidin.
What does a yellow patch of skin mean?
Yellow skin is most commonly caused by a condition called jaundice, which occurs when there is a high level of bilirubin in the blood. Bilirubin is a yellowish compound that is formed when old or damaged red blood cells break down.
What is the main cause of jaundice?
Jaundice is caused by too much bilirubin in the blood. This is known as hyperbilirubinaemia. Bilirubin is a yellow substance produced when red blood cells, which carry oxygen around the body, are broken down. The bilirubin travels in the bloodstream to the liver.
What is the fibrous protein that gives skin form and strength?
Collagen
These two structures are composed of flexible protein fibers, and they make up 70 percent of the dermis. Collagen (KAHL-uh-jen) is a fibrous protein that gives the skin form and strength.
Which protein is waterproof and skin?
keratin
The epidermal cells are: – 1 – the keratinocytes: compose most of the epidermis. They produce a protein: the keratin that helps waterproof the skin and that protects the skin and the underlying tissues from heat, microbes, abrasion and chemicals.
Which layer of the skin prevents water loss?
The stratum corneum prevents the entry of most foreign substances as well as the loss of fluid from the body. This layer, just beneath the stratum corneum, contains living keratinocytes (squamous cells), which mature and form the stratum corneum.
