Answer:
Sweat glands help keep endotherms cool. When an endotherm gets hot, the sweat evaporates and cools the animal's skin. Fur and feathers are another adaptation to regulate body temperature. These specialized skin coverings help the animals stay warm.
Answer:
mediates morphological changes in response to red and far-red light
Explanation:
Phytochrome is a blue-green protein pigment that participates in plant physiology in response to periodic light phenomena, responsible for numerous developmental processes. This substance, in two possible forms: phytochrome R (inactive) and F (active), is dissolved in the hyaloplasma of plant cells, capturing specific wavelengths from sunlight.
Depending on the time of day, ie the daily light, these two types of phytochrome can convert to each other, according to the wavelength absorption that comprises the frequency of the red color (long or short).
Thus, during the day, plants capture the red wavelength (660nm), transforming the phytochrome R and F, as well as the far-red wavelength (760nm), to a smaller extent, inverting the phytochrome F to R.
As the variation in daily light decreases (late afternoon), plants begin to capture the far-red wavelength more intensely, concentrating more phytochrome R than F. This inactivation action remains in the dark (during night). Therefore, the perception of this oscillation induces the vegetables to organic behaviors combined with the photoperiod.

Answer:
The triceps muscle extends when the biceps muscle is contracted.
Explanation:
The biceps and triceps muscles,work together in creating functional movement. These movements contribute to the ability to perform day to day tasks.
These muscles function in flexing and extending the arm. <em>Biceps for flexion</em> and<em> triceps for extension</em>. Both muscles work in an antagonistic fashion such that, the one doing the major motion is called the <em>primary mover</em> while the other muscle, is the <em>antagonist</em>. These muscles work in opposite direction, aiding the movement of the arm in both directions.
When biceps are contracted, the triceps are extended. Their antagonistic nature is beneficial because both muscles set the motion patterns at particular points. If we only had biceps extension of the elbow will be impossible and any movement that requires extension would not have been possible and vice versa.
