Answer:

(a) (i) Define the term "Green Revolution" as used during the period 1945 to 1985.

  • The use of modern agricultural techniques became widespread around many regions in the world. This led to higher yields through the use of fertilizers, pesticides, genetically modified seeds and mechanical machinery.  

(ii) Explain the principal agricultural practices/technologies associated with the green revolution.

  • extensive use of fertilizers, pesticides, genetically modified seeds and mechanical machinery.  

(iii) Name TWO regions, in different parts of the world, where the green revolution has had a significant impact on crop yields.

  • In North America, Mexican food production increased and they stopped importing food. Although currently that has reversed, and it is importing even more food than before.
  • In Brazil, agricultural production increased dramatically. Both total farmed area and yields have continued to increase in the past years becoming a threat to the amazon basin.

(b) Identify and discuss TWO social, political, or cultural conditions necessary for the success of the agricultural practices/technologies of the green revolution.

  • Emigration from rural areas to urban areas which resulted in a rapid expansion of urban centers. Since less labor was needed in farms, many people left rural areas due to lack of jobs.
  • People started accepting genetically modified crops, which were not well accepted at first. A lot of money was invested in research and development of new seeds, fertilizers and pesticides.

(c) Identify and discuss TWO significant economic or ecological factors that may limit the long-term success of the agricultural practices/technologies of the green revolution.

  • Many new agricultural techniques have resulted in a decrease of soil fertility. In many places crops cannot grow unless a lot of fertilizer is used.
  • Countries were the green revolution was originally successful, like Mexico (where it started), have reduced the total area dedicated to crops. As the yields increased, the price of food started to decrease and many small farms could not keep operating.

Every decision you make in a computer program involves evaluating one or more _____ expression(s).
fenix001 [56]

Answer:

Boolean expression.

Explanation:

Boolean algebra provides the operations and the rules for working with the set {0, 1}. In computer science, a Boolean expression is an expression in a programing language that produces a Boolean value when evaluated i.e. one of true or false.

Each Boolean expression represents a Boolean function. The values of this function are obtained by substituting 0 and 1 for the variables in the expression.

Are used mostly with while loops, and conditional statements and can be contrasted with arithmetic expressions which are expressions that evaluated to a number.

These expressions are made up of the three logical operators (AND, OR, NOT), the relational operator (> >= < = = <>) and functions that return true or false.

A. Calculate the net present value of the following project for discount rates of 0, 50, and 100%:
kherson [118]

Answer:

Net present value when discount rate is 0% = $15,750

Net present value when discount rate is 50% = $4,250

Net present value when discount rate is 100% = $0

IRR =100%

Explanation:

The net present value is the present value of after tax cash flows from a project.

The IRR is the discount rate that equates the after tax cash flows from an investment to the amount invested.

The net present value can be calculated using a financial calculator

Cash flow in year 0 = $-6,750

Cash flow for year one = $+4,500

Cash flow in year two = +18,000

Net present value when discount rate is 0% = $15,750

Net present value when discount rate is 50% = $4,250

Net present value when discount rate is 100% = $0

IRR =100%

Contact [7]

Answer:

Option B is correct because the first thing is we can not register it as trademark because the requirement to register trademark is:

  • It must be in use And
  • Must be distinctive.

In this case the word bicycle is not distinctive. The word distinctive in law means that the item must be different from something else either in nature or type.

Option A is incorrect as the word bicycle is not distinctive, so it can not be registered. And if it can not be registered then it can not be protected against trademark infringement.

Option C is also incorrect as this word does not meets the requirements of trademark registration.

Option D is also incorrect because certification mark are logos of products to make the quality or nature of product clear.

Crazy boy [7]

Answer:

D) purchasing euro call options.

If Lazer purchased euro call options it would be basically buying the right to purchase euros at a specified currency exchange rate. This way Lazer would know what is the maximum amount it will have to pay for the euros it needs to cover its debts. The call option give the buyer the right to purchase the euros but not the obligation, so if the euro depreciates, then Lazer can simply decide to not use the call option.
