Answer:
By researching, I would think that the answer is D. Ice crystals melt as they fall through a warm layer of air and then refreeze into small ice pellets as they pass through a colder layer of air.
Explanation:
<em>During precipitation formation, if temperatures are at or below freezing, 0°C (32°F), at cloud level, water in the air freezes into ice crystals, and the crystals stick together to make snow. The snow starts to fall, and if the air column is freezing cold all the way down from the clouds to the ground, the precipitation stays frozen. It simply falls as snow.</em>
<em />
<em>Sometimes, however, a temperature inversion occurs. Normally, the temperature decreases with increasing altitude. A temperature inversion is when a layer of warm air intrudes between the ground and the clouds.</em>
<em />
<em>Under these conditions, when the falling snow reaches the layer of warm air, it melts. Then it hits the layer of cold air just above Earth’s surface and refreezes. This all happens very fast, and the result is tiny ice pellets called sleet.</em>
The correct option is C.
When a dog is afraid, its ears are usually pinned back to the head. A dog showing aggression will pulled its ear up and forward.
Other signs that a dog shows when it is afraid include: lowering of the head, wrinkling of the nose, curled lips that show many teeth, tucked tail, panting, etc.
Signs show by an aggressive dog include: head held high, curled lips only show the front teeth, tail is upright and stiff, no panting, etc.

That's just the alimentary track (minus the couple that come before esophagus such as mouth and pharynx) so if you need digestive glands and accessory organs let me know cause I know those too
Growth Hormone deficiency is a medical condition wherein the pituitary gland is not able to produce enough growth hormones also known as somatropins. This can be acquired either in childhood or adulthood. This condition is called hypopituitarism. Hope this is the answer that you are looking for.
Answer:
This structure has not been highly beneficial for the organism
Explanation:
Vestigial structures are cells, tissues, and/or organs that have no apparent function. Vestigial structures are retained during the course of the evolution, but often they are degenerate and/or atrophied (due to disuse). In general, these structures are homologous to anatomical structures that play a specific role in evolutionarily related species. Some examples of vestigial structures include, among others, the presence of the appendix in humans and wings in flightless birds.
