weqwewe [10]

Answer:

It allows them to save energy

Explanation:

Hibernation is a behavioral adaptation that involves physiological changes to survive during wither months. These physiological changes can include a decrease in body temperature, respiratory/heart rate and metabolism. The main purpose for which animals enter hibernation is to conserve energy, thereby surviving adverse climatic conditions and/or periods when food is scarce. Some examples of true hibernators (i.e., animals that enter into a state of minimal activity) include bats, hedgehogs, allies, squirrels, marmots, etc.

Identify which layer of the integumentary system each of the following is most likely to be found and provide a one phrase descr
Zielflug [23.3K]

Answer:

The integumentary system comprises the skin, nails, hair and exocrine glands. The average persons skin weighs a approximately 9Kilograms and spans about  20 square feet.

Phagocytic cells: These are found in the dermis or hypodermis. The skin layer that lies directly beneath the epidermis and above the subcutaneous layer is the <em>dermis</em>. It is made up of fibrous and flexible tissue and is the thickest layer of the skin. It thus gives the skin power and flexibility.

Phagocytic cells are cells within the skin that are designed for detecting, engulfing, and destroying pathogens (such as bacteria and other harmful organisms) and apoptotic cells. Apoptotic cells are cells in the human body that have spent their lifespan and are ready for replacement.

Keratinocytes: This is the most common type of cell in the human skin. It is mostly found on the Epidermis and comprises about 95% of the same.

The Epidermis is the most visible part of the skin. It is the part of the skin which the eyes can see. Its function is mostly protective. It receives all nutrition from the dermis because it does not contain any blood vessels.

Arrector Pili Muscle: Beneath the skin, there are tiny muscles that are attached to the base of a hair follicle at one end and to dermal tissue on the other end. These are known as the Arrector Pili.

Papillae: The dermal papillae comprise a little amount of the dermis. They project out of the epidermis. They aren't always immediately visible on the surface of the skin but tend to be quite obvious when examined under a microscope.

Melanocytes: These are neural crest-derived melanin-producing cells. They are mostly found in the lower layer of the skin's epidermis (also known as the stratum basale), the middle layer of the eye (uvea), the inner ear, the vaginal epithelium, the meninges, the bones, and the core. A black pigment mainly responsible for skin color is melanin.

Paccinian corpuscles: can always be seen in the deep part of the dermis of both glabrous and hairy skin. Structurally, they are very much like the  Meissner's corpuscles.

Paccinian corpuscles can be found in the Periosteum of the bone, capsules of the joints, pancreas, other internal organs, breast, and genitalia.
