How do cells get the proteins they need from foods?
cholesterol from food is bonded together through dehydration synthesis to produce protein chains.
cells synthesize proteins from glucose absorbed from food during digestion.
enzymes break down food proteins into smaller molecules that can be carried by blood.
cells use sunlight to produce proteins from foods, carbon dioxide, and water.

What is called the "building block" of life?

Explain how ancient whale fossils found in eqypt are believed to support the theory of evolution.

The graph below compares the rates of reaction of a burning candle and an exploding firework. comparing chemical reactions what can you conclude from the graph? the reaction that causes a firework to explode requires less energy to start, and occurs more rapidly than the reaction that causes a candle to burn. the reaction that causes a firework to explode requires less energy to start, and occurs less rapidly than the reaction that causes a candle to burn. the reaction that causes a firework to explode requires more energy to start, and occurs less rapidly than the reaction that causes a candle to burn. the reaction that causes a firework to explode requires more energy to start, and occurs more rapidly than the reaction that causes a candle to burn. mark this and return
