Answer:
Rotation is when an item or object (specifically the earth) rotates on it's axis.
Revolution is when an item (the earth) orbits or "revolves" around another one (the sun).
The rotation of the earth determines how long a day lasts while the revolution (or orbit) determines how long a year lasts (with all of the season).
Also you don't have to put the ones in the parentheses ()
Answer:
the second one - cells are only found in plants and animals
Explanation:
The similarity between the blood cells and stomach cells is ; Both help maintain homeostasis ( B )
The stomach cells helps in the storage of food ,enzyme secretion and digestion of food substance consumed. this way they help to maintain the acidity and water level in the body through the process of food digestion and enzyme/acid secretion.
The blood cells transports oxygen from the lungs to the tissues where they are needed and also taking back CO₂ from the tissues to the lungs. the blood cells also carries the necessary nutrients from the digested food to the various tissues. this way the blood cells help to maintain homeostasis in the body.
Hence we can conclude that the similarity between the blood cells and stomach cells is ; Both help maintain homeostasis

Answer:
All chemical elements that are needed by living things are recycled in ecosystems, including carbon, nitrogen, hydrogen, oxygen, phosphorus, and sulfur. Water is also recycled.
Of the many processes involved in the water cycle, the most important are evaporation, transpiration, condensation, precipitation, and runoff
Earth’s water is constantly in motion. Although the water on Earth is billions of years old, individual water molecules are always moving through the water cycle. The water cycle describes the continuous movement of water molecules on, above, and below Earth’s surface. Like other biogeochemical cycles, there is no beginning or end to the water cycle. It just keeps repeating. During the cycle, water occurs in its three different states: gas (water vapor), liquid (water), and solid (ice). Processes involved in changes of state in the water cycle include evaporation, sublimation, and transpiration.
