Answer:
Enzymes are very efficient catalysts for biochemical reactions. They speed up reactions by providing an alternative reaction pathway of lower activation energy. Like all catalysts, enzymes take part in the reaction - that is how they provide an alternative reaction pathway.
Explanation:
Answer: D). Most rocks are a mixture of minerals
Rocks are the natural substances these are the aggregate of one or more number of minerals. These minerals are responsible for chemical and physical nature of rocks. These are responsible for type of particles, texture of particles and overall rock structure. Example of rock having mineral aggregate is granite which is a combination of minerals like quartz, biotite and feldspar.
Converting the temperature to Kelvin,
because Boyle's law is (Pressure 1) (Volume 1) = (Pressure 2) (Volume 2) and there's no need for temperature.
Soil particles vary greatly in size, and soil scientists classify soil particles into sand, silt, and clay. Starting with the finest, clay particles are smaller than 0.002 mm in diameter. Some clay particles are so small that ordinary microscopes do not show them. Silt particles are from 0.002 to 0.05 mm in diameter.
