What is the influence of temperature on a chemical change?
Answer:
Increasing the temperature will cause chemical changes to occur faster. Decreasing the temperature, causes the particles to lose energy which causes them to move around less and slower. The less they move, the less collisions occur, and the less reactions occur between the chemicals = slower reaction rate.

Mammals use their lungs to provide oxygen for themselves from the air. Fish spend a majority of their time in the water, and instead, developed gills. What is the function of gills? *
a-Gills break down water into hydrogen and oxygen so the fish can use the oxygen.
b-Gills allow the fish to breathe oxygen in the water and the air.
c-Gills allow the fish to use the oxygen that is dissolved in the water.
d-Gills allow the fish to use the oxygen in the air, but use it more slowly so they can live in water.
The Barber's have a circular flowerbed in their front yard. The want to put fertilizer on ha
Answer:
C
Explanation:
a fish cant breath outside water
Mammals use their lungs to provide oxygen from the air, while fish spend time in the water; instead, fish developed gills because gills allow the fish to use the oxygen that is dissolved in the water, which is option c.
What is the significance of the gills in animals?Gills are important for fish and other aquatic animals as they are the primary respiratory organ in aquatic animals, helping them obtain oxygen from water and release carbon dioxide into the surrounding water. Gills in fish and other aquatic animals help them breathe underwater and maintain vital metabolic processes.
Hence, mammals use their lungs to provide oxygen from the air, while fish spend time in the water; instead, fish developed gills because gills allow the fish to use the oxygen that is dissolved in the water, which is option c.
