When succulent xerophytes (hot desert plants) are exposed to high temperatures, their leaves develop sunken stomata. The rate of transpiration is lowered by sunken stomata, which guarantee less water loss. Take a look at the picture below:

One kind of carotenoid pigment is xanthophyll. Fruits and vegetables get their yellow, orange, and red hues from pigments called carotenoids. Xanthophyll is not a nitrogenous waste because it does not contain nitrogen.

One kind of tissue made up of flat, scale-like cells is called squamous epithelium. It lines the body’s cavities and blood vessels and forms the epidermis, the skin’s outermost layer. The outermost layer of a frog’s skin may slough or shed after being submerged in water for a while. To get rid of old or damaged skin, the squamous epithelium sheds during this process.

Urine with alkaptonuria, an inherited disorder, turns black when it comes into contact with air.

The body needs to cool down in hot weather, which is accomplished by increasing blood flow to the skin, which causes more heat to be released from the blood, and increasing the production of sweat, which cools the body when it evaporates. For this reason, options A and C are incorrect. Options A and B are incorrect because dilating the vessels increases their diameter, which in turn allows more blood to flow. Option D is the one with the right combination.

The process by which the body keeps a steady internal environment in spite of changes in the external environment is known as homeostasis. It involves a number of physiological processes that control variables like blood glucose levels, pH, temperature, and more, guaranteeing ideal circumstances for the healthy operation of cells and tissues.
