Water resources include water contained in oceans and seas. select the best answer from the choices provided t f

FALSE

Explanation:

The water resource is usually referred to those water that is used for various purposes such as agriculture, drinking, industrial purpose and many others. This water is generally known as the freshwater which includes the rivers, streams, lakes, ponds, glaciers, ice and the groundwater. This forms only about 2.5 to 3% of the total water content present on earth. It is the most important resource because all living organism require fresh water for their survival.

The majority of the earth's water is present in the ocean which is almost entirely saline. This saline water is not useful for the living organisms because of their high salt content.

Thus, water resources do not include ocean and seawater. So the above-given statement is False.

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

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.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
