Plants and animals share a very long history of intimate relationships and have evolved in response to each other’s influence. Briefly describe three actual relationships or interactions between plants and non-human animals. One should be mutually beneficial to both species, one should benefit the plant at the expense of the animal, and one should benefit the animal at the expense of the plant. Be sure to include details of the relationship, including the names of the organisms and specific benefits or expenses involved.

b)  Two firms merge together, only if the transaction cost must be reduced.

c)  Specic human capital is a barrier of vertical integration.

d)  The benefit of coordination gives rise to vertical integration.

e)  Consumer surplus decreases after two rms merge with each other.

• Consider this week's reading by Kotler, where he states that "... needs are not created by advertising, but are a basic part of human make-up" (1983, p.8)
• Do you agree with Kotler? Why or why not?

You are required to think deeply about these questions, and form an opinion whether you either agree or disagree with Kotler. We don't mind whether you agree or disagree, it's all about how you justify your position.

Calculate the molarity of each of the following solutions:
