Jasmine is healthy girl who is playing outside. Her internal body temperature rises to 38°C, which is above normal.
lisov135 [29]

Answer:

Jasmine's body responds with a mechanism of heat loss, such as sweating and evaporation, to reduce her internal body temperature and recover homeostasis.

Explanation:

The human is a homeotherm organism, with a constant body temperature that is between 36.5 and 37 °C. To maintain thermal homeostasis uses several mechanisms.

In the case of Jasmine, the raise of the body temperature, with the exercise, to 38°C stimulates sweat production and its body surface becomes moist. With the evaporation of sweat, body temperature normalizes, since this process involves heat loss.

Also, a voluntary mechanism to lower the temperature is to remove the clothes and remain in a cool environment.

Describe how the integumentary system responds to differences in sunlight
Mama L [17]

The integumentary system (skin) reacts different on different sun intensity (different length exposure to sun).

For example, moderate exposure to the sunlight contributes to the production of melanin and vitamin D by the body. On the other hand, high exposure to sunlight can have negative health effects such as sunburn, which is an inflammatory response to DNA damage caused by UV radiation.

What are three environmental factors that can influence plant phenotypes
sergij07 [2.7K]

The genotype describes the complete set of genes inherited by an individual, and the phenotype describes all aspects of the individual's morphology, physiology, behavior, and ecological relations. Light, water, temperature, soil structure are the environmental factors which influence the plant phenotype most. The growth is a very sensitive phenotypic trait that quickly responds to any sub-optimal environment. However, many more physiological responses occur that turn out in phenotypes that can be measured with non-invasive technology.
