TEKS B 10A The pygmy sperm whale, Kogia breviceps, has a fluid-filled sac within the lower portion of its intestine. When threatened, the pygmy whale ejects a dark brown liquid from the fluid-filled sac and simultaneously dives in an attempt to avoid predators. Scientists are not sure I the cloud of up to 3 gallons of feces discourages or confuses the predators, Which two systems alert the pygmy whale to danger and help produce the brown liquid it accumulates and uses as a defense?​

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
