If lactic acid builds up in the body more quickly than it can be removed, acidity levels in bodily fluids — such as blood — spike. lactic acid buildup occurs when there's not enough oxygen in the muscles to break down glucose and glycogen.
Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
That is true.
These are the three types:
Igneous- form when magma cools down and hardens.
Metamorphic- form under earth's surface after particles undergo intense heat and pressure.
Sedimentary- forms when different layers of sediment accumulate on top of each other and harden creating a solid piece.
