Oceans, Seas, and bodies of fresh water
Explanation:
The factors that affects the rate of chemical reactions are;
- Nature of reactants
- Concentration of reactants or pressure
- Temperature
- Presence of catalyst
- Sunlight
In our body, the nature of reactants is very important. A food substance in solid form undergoes slow digestive process because it has little surface area exposure for the action of digestive chemicals. Most solid food are usually chewed in the mouth before digesting them to increase their surface area.
The increasing order of food digestion is;
lumps to granules to powder and to liquids.
Science include hypothesis
Explanation:
The speed of sound depends on the elasticity and density of the medium through which it is traveling. In general, sound travels faster in liquids than in gases and faster in solids than in liquids. The greater the elasticity and the lower the density, the faster sound travels in a medium.
D. Certain genes are turned on and others are turned off; this action produces adult cells that are specialized
