Some ethical standards are required to evaluate the morality of all human activities. Explain Biopiracy.

Imagine that all the exhaustible natural resources are exhausted by human activities. Do you think survival of living beings would be possible.? If yes, why?, If not, why not?

Global carbon is fixed in the biosphere through photosynthesis. (a) Explain any two ways by which carbon is returned to the atmosphere through natural processes, (b) List any two human activities that have influenced the carbon cycle in nature.

How have human activities caused desertification ? Explain.

Whenever the terms on the two sides of the equation are of different nature, then equations are known as Non standard form, some of them are in the form of an ordinary equation but can not be solved by standard procedures. Now standard problems require high degree of logic, they also require the use of graphs, inverse properties of functions, inequalities. On the basis of above information, answer the following questions: The number of real solutions of the equation sin(e^(x)) = 5^(x)+5^(-x) is
