<span>Catalysts increase the rate of reaction without being used up. They do this by lowering the activation energy needed. With a catalyst, more collisions result in a reaction, so the rate of reaction increases. Different reactions need different catalysts.</span>
Dead organic matter from the plants in the form of litter and root exudate (including acids, sugars, polysaccharides and ectoenzymes) and dead roots are processed by living organisms in the soils.
<span>For example, earthworms may substantially improve soil condition in newly formed soils, such as in post mining sites. In the same time, earthworms can also cause severe negative impacts by bringing invasive exotic species to the ecosystem.</span>
Plants<span>, </span>animals<span> and micro-organisms (fungi and bacteria) all affect </span>soil formation<span> by producing or contributing to humus production. The amount of humus in a </span>soil<span> is a result of how much </span>plant material has been incorporated into it.

The type of solution researchers should use to cause blood cells to lyse (burst) would be a hypoosmotic solution. It is a solution which has lesser solute concentration in relation with another solution. For instance, a cell of a fish from fresh water would be hypoosmotic to salt water.

The reason w<span>hy you would expect such diseases to produce widely varying symptoms because </span><span>connective tissues and collagen inside it are found everywhere in the body! so almost all of body organs are involved in these disorders.</span>
