Which of the following statements best describes the carbon atoms present in grass-eating cows?
Temka [501]

Answer:

d. The carbon atoms came from carbon dioxide and were incorporated into sugars through photosynthesis in the grass.

Explanation:

Grass eating cows are heterotrophs and can not synthesize the organic sugars by themselves. They derive it from grasses they eat.  

Grasses are the autotrophs that can fix atmospheric carbon dioxide into glucose in the presence of sunlight by the process of photosynthesis. The extra glucose formed during photosynthesis is stored in the cells of grasses in the form of starch and becomes a source of carbon for herbivores such as cows.

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>
