Answer:
Relaxation of the dartos muscle.
Explanation:
Testes are present in scrotum outside the pelvic cavity to maintain the temperature about 2-3 degrees Celsius below the body temperature as required for sperm production. Dartos muscle is the layer of smooth muscle located in the superficial fascia. The contraction of dartos muscle serves to make the skin of the scrotum wrinkled and tight.
During hot weather, the dartos muscle relaxes and makes the surface of scrotum less wrinkled to increase the loss of the heat from its surface. The increased heat loss from the surface of scrotum due to relaxed dartos muscles keeps the testes protected from heat.

Hope this helps!!
Explanation:
Glaciers act as reservoirs of water that persist through summer. Continual melt from glaciers contributes water to the ecosystem throughout dry months, creating perennial stream habitat and a water source for plants and animals. The cold runoff from glaciers also affects downstream water temperatures.
Answer:
Temperate rain forests have <em>Cold winters and warm summers, and broad-leafed deciduous trees like oaks are dominant </em>(Option E)
Explanation:
Temperate forest biome characterizes for having deciduous trees such as oaks, maple, or olms, among other phanerophyte species. These plant species lose their leaves every year during the cold and dry autumns and winters, being these seasons the most limiting period over the year. Foliage resprout again during the warmer wet season when it rains more often, during spring and summer.
These forests are located between 30º and 60º latitude in both hemispheres. Precipitations might be over 1000mm.
Soils are very fertile and deep, due to the leaves´ loss that provides nutrients to the soil and protect it from erosion.
okay thank you I semi dont understand but hey :)
