According to the equilibrium model of island biogeography
1. immigration rate increases with the number of species on
the island
2. small islands tend to have a greater rates of immigration
than large islands
3. Islands that are far from the mainland tend to have a
greater rates of extinction then similar islands that are close to
the mainland
4. Smart islands tend to have a greater rates of extinction
than larger islands
5. extinction rate decreases with increasing number...
Use the AD-AS model based on the misperception theory to analyze
the general equilibrium effects of an increase in consumer optimism
on output and the price level. Describe how the economy is affected
in the short run before prices adjust and describe its evolution
after prices adjust. Use a graph to illustrate your answer.
''Irrespective of the structure of the labour market, economic
theory predicts that the imposition of a minimum wage above the
otherwise prevailing wage unambiguously reduces employment”.
Discuss the validity of the above statement both on the basis of
economic theory and in light of the existing empirical evidence
The theory of behavioral or communication-style bias is based
on a number of underlying principles. List the
principles and give very detailed examples.
Why does the product of two numbers -having no common factors- that results in a perfect square, make them-the two numbers- perfect squares themselves?
15. The island of Flores was home to a small hominid named Homo
floresiensis. This species was smaller than most hominids and
isolated on the island. Describe how this species may have adapted
to life on the island and provide a reasonable hypothesis regarding
which known hominid they likely evolved from.

A species of finches on the Galapagos Island has a geometric
growth pattern. The island has 25 000 finches in the first year. In
the same year, there are 5000 births and 3500 deaths. What is the
geometric growth rate Calculate the population after 5 years A
population of walruses on an island in the South Pacific Ocean
shows continuous growth.
The carry capacity of the environment is 10 000 and r = 0.5.
What is the rate...
Genetic theory predicts that, in the second generation of a
cross of sweet pea plants, blossoms will be either red or white,
with each plant independently having a 70% chance of producing red
blossoms. Out of 20 plants selected at random from the second
generation of this cross, let X be the number that have red
blossoms. (a) What is the probability distribution of X? [3] (b)
Calculate: (i) the mean and standard deviation of X. [3] (ii) P( X...
Genetic theory predicts that, in the second generation of a
cross of sweet pea plants, flowers will be either red or white,
with each plant having a 25% chance of producing red flowers.
Flower colours of separate plants are independent. Let X be the
number of plants with red flowers out of 20 plants selected at
random from the second generation of this cross. (a) What is the
probability distribution of X? [3] (b) Calculate: (i) the mean and
