The phosphorous cycle is referred to as a local cycle because it involves an element with no mechanism for long distance transfer.
Phosphorous cannot be found in the air in the gaseous state because it is usually a liquid at standard temperature and pressure and is thus limited in being recycled through water, soil and sediments. However very small particles in the air may contain phosphorous or its compounds.
The phosphorous cycle is the slowest one of the sedimentary cycles.
Answer:
Option B and C
Explanation:
When a population is said to be in Hardy Weinberg’s Equilibrium, it is assumed to obey the following assumptions –
a) There is random mating among the organism
b) The mating should not be selective and in order to achieve so the population size must be infinite
c) There should be no loss or gain of allele thereby assuring that there is no selection, mutation, migration etc.
d) Also there must be no crossing among organism belonging to different generation
With all such assumptions, the allele frequencies will remain either constant thereby producing infertile recessive homozygous species or fertile heterozyous species.
Hence, option B and C are correct

The same general processes occur in meiosis and mitosis
Although the operation of natural selection requires that genotypes differ in fitness, for some geneticists it seems easier to understand natural selection than fitness. Partly this reflects the fact that the word “fitness” has been used to mean subtly different things. Here I distinguish among these meanings (e.g., individual versus absolute versus relative fitness) and explain how evolutionary geneticists use fitness to predict changes in the genetic composition
